Mechanistic narrative

Synthesis pass · prose summary of the discoveries below

THOC5 is a subunit of the mammalian THO/TREX complex that acts as a selective mRNA export adaptor coupling co-transcriptional 3'-end processing to nuclear export of a defined subset of transcripts rather than bulk mRNA (PMID:19165146, PMID:21525145). It binds directly to a distinct, non-overlapping surface on the Ntf2-like middle domain of the Tap export receptor—allowing simultaneous Tap engagement by THOC5 and the Aly adaptor—and exhibits intrinsic RNA-binding activity within stable THO mRNPs (PMID:19165146). Through direct interaction with the cleavage/polyadenylation machinery, THOC5 governs poly(A) site choice: it loads CFIm68 co-transcriptionally to favor distal polyadenylation sites and recruits CPSF100 to the 3'UTRs of target genes, so that loss of THOC5 yields chromatin-retained transcripts, shortened 3'UTRs, and failed export (PMID:23685434, PMID:25274738). THOC5 is recruited to chromatin near sites of high RNA polymerase II density and, via interaction with CDK12 and THOC6, modulates polymerase II elongation rate and CDK12 recruitment to R-loops, mechanistically linking it to transcription as well as processing (PMID:36590164). The factor is selectively required for export of inducible and immediate-early transcripts—including heat-shock, M-CSF, Wnt, and serum-responsive genes (Hsp70, Ets1, Sox9, Ascl2, Myc, and immediate-early genes)—with over 90% of serum-induced immediate-early genes failing induction upon THOC5 loss (PMID:21525145, PMID:24157873, PMID:24267292, PMID:25274738). THOC5 activity is gated by signaling-dependent phosphorylation: PKC phosphorylates serines 5/6 adjacent to its NLS to drive nuclear-to-cytoplasmic translocation (PMID:15221008), Src-family and leukemogenic tyrosine kinases phosphorylate Y225 to control mRNA-binding and chemokinesis (PMID:23032722, PMID:26919114), and the ATM-p53 pathway suppresses its mRNA-binding after DNA damage (PMID:21937706). Consistent with its role in inducible gene expression, conditional deletion in mice causes rapid apoptosis of hematopoietic progenitors and disrupts intestinal epithelial homeostasis, and its activity is co-opted in leukemia and breast cancer stem-like states (PMID:20051105, PMID:24267292, PMID:34708581).

2009 THOC5 binds to a distinct, non-overlapping surface on the middle (Ntf2-like) domain of the Tap export receptor, allowing simultaneous binding of both THOC5 and the adaptor protein Aly to Tap-p15. THOC5 exhibits in vitro RNA-binding activity and associates with HSP70 mRNPs in vivo as a component of the stable THO complex. Nuclear export of HSP70 mRNA specifically requires both THOC5 and Aly, but THOC5 is not required for bulk mRNA export. Co-immunoprecipitation, in vitro binding assays (GST pulldown), RNA-binding assays, in vivo mRNA export assays with knockdown The EMBO journal High 19165146
1999 THOC5/FMIP (MW ~78 kDa) binds transiently via its N-terminal 144 residues to the cytoplasmic domain of activated (ligand-stimulated) c-Fms tyrosine kinase receptor. Binding is followed by rapid tyrosine phosphorylation of FMIP within the binding domain, which drastically reduces its association with Fms. No binding was observed with the cytoplasmic domains of c-Kit, TrkA, c-Met, or the insulin receptor. Co-immunoprecipitation, GST-Fms fusion protein pulldown, deletion mutagenesis Oncogene High 10597251
2004 THOC5/FMIP is phosphorylated by protein kinase C (PKC) on serines 5 and 6, adjacent to its nuclear localization signal (NLS). This NLS is essential for predominantly nuclear localization. PKC-mediated phosphorylation on S5/S6 causes translocation of THOC5 from nucleus to cytosol. Phosphomimetic mutations (SS5,6EE) promoted cytoplasmic localization and enhanced M-CSF-mediated survival/differentiation, while non-phosphorylatable mutant (SS5,6AA) remained nuclear even in the presence of activated PKCα. Site-directed mutagenesis (phosphomimetic and non-phosphorylatable mutants), subcellular fractionation/localization imaging, functional differentiation assay Oncogene High 15221008
2008 THOC7 lacks a typical nuclear localization signal (NLS) and resides mainly in the cytoplasm on its own, but directly binds to the N-terminal portion (residues 1-199) of THOC5/FMIP via THOC7 residues 50-137. This interaction is required for THOC5-dependent nuclear transport of THOC7: in the presence of THOC5, THOC7 is transported into the nucleus; a THOC7 mutant lacking the FMIP-binding site fails to co-localize with FMIP. Co-immunoprecipitation, deletion mutagenesis, subcellular localization imaging (co-transfection/co-localization) FEBS letters High 19059247
2006 THOC5/FMIP overexpression in C2C12 cells prevents adipocyte differentiation and promotes granulocyte/muscle phenotype, while FMIP knockdown promotes adipocyte lineage commitment and impairs muscle differentiation. Mechanistically, FMIP-overexpressing cells lack polyadenylated C/EBPα mRNA but retain C/EBPα pre-mRNA (detected by Northern blot and RT-PCR), implicating FMIP in RNA processing/export of C/EBPα. THOC1 co-precipitates with FMIP, placing it in the THO complex in this context. Ectopic expression and siRNA knockdown, Northern blot, RT-PCR, co-immunoprecipitation Oncogene Medium 16909111
2010 Conditional knockout of THOC5 in mice leads to rapid apoptosis of hematopoietic progenitor cells (committed myeloid progenitors and long-term reconstituting cells) within days, demonstrating THOC5 is essential for hematopoietic primitive cell survival in vivo. Mechanistically, THOC5 depletion causes down-regulation of its direct interacting partner THOC1, potentially disrupting THO complex function. Interferon-inducible conditional knockout mouse, bone marrow transplantation rescue, flow cytometry, histology BMC biology High 20051105
2011 THOC5 is required for export of a specific subset (~10 identified) of mRNAs (including HoxB3, CBX2); these mRNAs are spliced but not exported to the cytoplasm in THOC5-depleted MEF cells and co-purify with THOC5. Hsp70 mRNA export is specifically dependent on THOC5 under heat shock (42°C) but not under normal conditions (37°C), indicating THOC5 is required for stress-induced mRNA export rather than basal export. Conditional knockout (Cre-lox MEF cells), transcriptome analysis of cytoplasmic RNA, RNA co-immunoprecipitation (RIP) RNA (New York, N.Y.) High 21525145
2013 THOC5 physically interacts with CFIm68 (large subunit of mammalian cleavage factor I involved in polyadenylation site choice). Most likely via direct Thoc5–CFIm68 interaction. THOC5 depletion selectively attenuates expression of mRNAs polyadenylated at distal polyadenylation sites (phenocopying CFIm68 depletion) and globally reduces CFIm68 association with the 5' regions of genes (by ChIP-seq), indicating THOC5 controls polyadenylation site choice by co-transcriptional loading of CFIm68. Co-immunoprecipitation (antibodies against different TREX components), microarray, ChIP-seq, siRNA knockdown Nucleic acids research High 23685434
2013 THOC5 is localized in nuclear speckles and translocates from nucleus to cytoplasm during M-CSF-induced macrophage differentiation. THOC5 is required for processing/export of a subset of M-CSF-inducible mRNAs (including Ets1); depletion causes accumulation of unspliced Ets1 mRNA in the nucleus. THOC5 is recruited to chromatin at the Ets1 gene locus and binds both unspliced and spliced Ets1 transcripts. Immunofluorescence/subcellular localization, tamoxifen-inducible conditional KO, transcriptome analysis, chromatin immunoprecipitation (ChIP), RNA immunoprecipitation (RIP) Cell death & disease High 24157873
2013 THOC5 is required for processing and export of a subset of Wnt target mRNAs (Sox9 and Ascl2, but not Fn1) in intestinal epithelium; these mRNAs co-purify with THOC5 by RIP. THOC5 is also required for expression of the Toll-like receptor-inducible gene COX2/Ptgs2, whose transcript is a THOC5 target mRNA. THOC5 deficiency disrupts gut epithelial differentiation and self-renewal, causing bacterial translocation and sepsis in mice. Tamoxifen-inducible conditional knockout mouse, RNA co-immunoprecipitation (RIP), transcriptome analysis, histopathology BMC cell biology High 24267292
2014 THOC5 forms a complex with polyadenylation-specific factor 100 (CPSF100) upon serum stimulation. THOC5 is required for recruitment of CPSF100 to the 3'UTR of THOC5 target genes (including Id1, Id3, Wnt11, Myc, Smad7). Without THOC5, a subset of IEG transcripts fail to be released from chromatin or are released with shortened 3'UTRs and impaired nuclear export. Over 90% of immediate-early genes fail to be induced by serum in THOC5-depleted cells. Interactome analysis (THOC5 as bait/MS), chromatin association assays, transcriptome analysis, serum stimulation experiments with siRNA knockdown Nucleic acids research High 25274738
2011 ATM kinase pathway regulates THOC5 mRNA-binding activity in response to DNA damage. DNA damage decreases cytoplasmic levels of THOC5-dependent mRNAs and impairs THOC5/mRNA complex formation. The C-terminal domain of THOC5 (not phosphorylation at S307/312/314 in the PEST domain) is required for this regulatory response. ATM kinase inhibitor (KU55933) or siRNA against ATM or p53 restores THOC5-dependent mRNA export after DNA damage, indicating the ATM-p53 pathway suppresses THOC5 mRNA-binding ability. Site-directed mutagenesis (S307/312/314A and C-terminal deletion mutants), RNA immunoprecipitation (RIP), ATM kinase inhibitor treatment, siRNA knockdown of ATM and p53 RNA (New York, N.Y.) High 21937706
2012 THOC5 phosphorylation on tyrosine 225 is mediated by Src PTK and reversed by CD45 protein tyrosine phosphatase, and is elevated in CML stem cells. This Y225 phosphorylation specifically governs THOC5 mRNA-binding activity (site-directed mutagenesis of Y225 modulates motile response to CXCL12). CXCL12 chemokine stimulation also induces THOC5 Y225 phosphorylation. THOC5 Y225 phosphorylation is sensitive to frontline CML drugs (imatinib). Site-directed mutagenesis (Y225), mass spectrometry (phosphorylation site identification), in vitro kinase/phosphatase assays, RNA-binding assay, chemokinesis assay, primary CML patient cells Leukemia High 23032722
2008 TEL/PDGFRB leukemogenic tyrosine kinase increases THOC5 expression and phosphorylation; elevated THOC5 expression increases PIP3 (phosphatidylinositol 3,4,5-trisphosphate) levels and decreases apoptosis. Mass spectrometry identified the TEL/PDGFRB phosphorylation site on THOC5, which is also a target for multiple other leukemogenic tyrosine kinases. Mass spectrometry (phosphosite identification), PIP3 measurement, apoptosis assay, ectopic expression British journal of haematology Medium 18373705
2008 THOC5 forms a complex with the transcription factor C/EBPβ (detected by co-immunoprecipitation). Ectopic THOC5 expression mimics M-CSF-stimulated monocytic maturation and enhances protein expression of C/EBPβ, C/EBPα, PU.1, and GAB2. THOC5-induced increases in PtdInsP3 are required for elevated C/EBPβ, as PI3K inhibition abrogates this effect. Co-immunoprecipitation, ectopic expression, PI3K inhibition, PtdInsP3 measurement Cellular signalling Medium 19015024
2021 THOC2 promotes stem-like properties and radioresistance of triple-negative breast cancer cells in a THOC5-dependent manner by facilitating nuclear export of SOX2 and NANOG mRNA transcripts. Silencing THOC5 decreases SOX2 and NANOG protein expression and depletes stem-like properties. siRNA knockdown of THOC2 and THOC5, xenograft tumor assays, protein expression analysis Advanced science Medium 34708581
2022 THOC5 depletion results in altered 3' cleavage of >50% of mRNAs and decreases RNA polymerase II elongation rates in vivo. THOC5 is recruited to chromatin preferentially near high-density polymerase II sites. In slow polymerase II cells, chromatin-associated THOC5 interacts with CDK12 (a transcription elongation modulator), RNA helicases DDX5, DDX17, and THOC6. The CDK12-THOC5 interaction promotes CDK12 recruitment to R-loops in a THOC6-dependent manner.

2024 The cancer-associated SF3B1 K700E mutation attenuates SF3B1 interaction with THOC5, reduces THOC5 binding to a subset of mRNAs, and inhibits nuclear export of those mRNAs. Overexpression of THOC5 restores nuclear export of these mRNAs in SF3B1 K700E cells. Other cancer-associated SF3B1 mutations similarly inhibit mRNA nuclear export via this mechanism.

2022 THOC5 shuttles between nucleus and cytoplasm in an M-CSF signaling-dependent manner in osteoclast precursors. THOC5 binds to FICD (a proteolytic cleavage product of c-FMS receptor) and facilitates nuclear translocation of FICD. THOC5 knockdown suppresses osteoclast differentiation partly by reducing RANKL-induced FOS and NFATc1 expression. siRNA knockdown, co-immunoprecipitation (THOC5-FICD interaction), subcellular fractionation/localization, osteoclast differentiation assay European journal of cell biology Medium 35688054
2016 MPL W515L mutant receptor induces phosphorylation of THOC5 on tyrosine 225, which mediates dysregulation of MYC mRNA expression (RNA transport) and increased chemokinesis. This was demonstrated by site-directed mutagenesis showing that THOC5 Y225 phosphorylation is required for MPL W515L-mediated effects on chemokinesis and MYC expression.
