Mechanistic narrative

Synthesis pass · prose summary of the discoveries below

CDC25C is a dual-specificity phosphatase that drives the G2/M transition by activating the cdc2(Cdk1)-cyclin B kinase, and its own phosphatase activity is in turn amplified through a positive feedback loop in which active cdc2-cyclin B phosphorylates CDC25C on multiple sites to increase its activity 2-3-fold and trigger premature mitotic entry (PMID:8428594, PMID:8119945). This autoamplification is held in check during interphase by PP2A, which keeps CDC25C dephosphorylated and inactive; the conformation-specific PP2A:B56δ holoenzyme, acting on trans pSer/Thr-Pro motifs generated by Pin1-catalyzed prolyl isomerization, restrains CDC25C and Cdk1 activity until mitotic exit (PMID:8389619, PMID:11090625, PMID:18056802). CDC25C activity and localization are governed by an extensive phosphorylation network: inhibitory phosphorylation of Ser216 by Chk1, Chk2, C-TAK1, and CaMKII creates a 14-3-3 binding site that enforces cytoplasmic retention by blocking nuclear import, working together with an intrinsic N-terminal nuclear export signal (PMID:9278512, PMID:9543386, PMID:11313932, PMID:14517314, PMID:12386164, PMID:10864927), while activating phosphorylation by Plk1/PLK on Ser198, by Plk3 on Ser191, and by ERK/MAPK on Thr48 overcomes nuclear exclusion and stimulates phosphatase activity at mitotic entry (PMID:11897663, PMID:11202906, PMID:14968113, PMID:17382881). This network couples CDC25C to checkpoint and stress signaling: DNA-damage and replication checkpoints converge on Ser216 phosphorylation and 14-3-3 sequestration to enforce G2 arrest (PMID:9278512, PMID:10681541), stress kinases such as JNK inactivate CDC25C, and oxidative stress drives an intramolecular disulfide bond that triggers degradation (PMID:11925443, PMID:12742231, PMID:20220133). CDC25C levels are further controlled by p53, which represses its transcription both by direct promoter binding and through the p21-dependent DREAM/CDE-CHR pathway, and by Mdm2, which promotes ubiquitin-independent proteasomal degradation, together enforcing G2/M arrest (PMID:15574328, PMID:28806397, PMID:26595675). Beyond mitotic control, CDC25C dephosphorylates the activation-loop Thr838 of ASK1 to suppress apoptosis during interphase, and a centrosomal pool co-localizes with cyclin B1 to locally amplify Cdk1 activation (PMID:25633196, PMID:18604163). Genetic ablation in mice shows CDC25C is dispensable for normal cell cycles, indicating functional redundancy with CDC25A/B (PMID:11359894, PMID:15767688).

1997 CDC25C is phosphorylated on serine-216 throughout interphase (but not mitosis), and this phosphorylation mediates binding to 14-3-3 proteins. A S216A mutation abrogated 14-3-3 binding and allowed cells to escape G2 checkpoint arrest induced by unreplicated DNA or radiation. Chk1 phosphorylates CDC25C on serine-216 in vitro, establishing the checkpoint kinase–CDC25C–14-3-3 axis.

1993 CDC25C phosphatase activity is directly activated by phosphorylation by the cdc2-cyclin B kinase in mitotic HeLa extracts and in vitro. Phosphorylation of CDC25C is required for activation of cdc2-cyclin B and entry into M-phase, establishing a positive feedback (autocatalytic) loop at the onset of mitosis. In vitro kinase/phosphatase assay, Xenopus egg extract activation assay, oocyte maturation assay, thiophosphorylation experiments The EMBO journal High 8428594
1993 PP2A (type-2A phosphatase) maintains CDC25C in a dephosphorylated, low-activity state during interphase in Xenopus egg extracts. Inhibition of PP2A by okadaic acid prevents CDC25C dephosphorylation and prematurely activates cdc2-cyclin B, while addition of PP2A catalytic subunit blocks kinase activation. This places PP2A as a negative regulator upstream of CDC25C in a positive feedback loop.

1994 cdc2-cyclin B phosphorylates CDC25C on five specific sites in vitro and in vivo at the G2-M transition. Phosphorylation by cdc2-cyclin B increases CDC25C phosphatase activity 2–3-fold. Only phosphorylated CDC25C (not unphosphorylated) effectively induces premature prophase when microinjected into living fibroblasts, demonstrating that multisite phosphorylation by cdc2-cyclin B drives the autoamplification loop.

1998 C-TAK1 (Cdc25C-associated protein kinase 1) phosphorylates CDC25C on serine-216 in vitro and in vivo. C-TAK1 physically interacts with CDC25C (co-immunoprecipitation in COS-7 cells). Co-production of C-TAK1 and CDC25C in bacteria results in stoichiometric S216 phosphorylation and facilitates 14-3-3 binding in vitro. In vitro kinase assay, co-immunoprecipitation, bacterial co-expression, 14-3-3 binding assay Cell growth & differentiation High 9543386
1999 CDC25C is retained in the cytoplasm during interphase in human cells. A 58-amino-acid region (aa 201–258) containing the 14-3-3 binding site is required for cytoplasmic localization. Mutations disrupting 14-3-3 binding cause pancellular redistribution and increased ability to induce premature chromosome condensation. Gamma irradiation or leptomycin B did not alter cytoplasmic localization, suggesting 14-3-3 binding (not NES) is the dominant mechanism for cytoplasmic retention during interphase. Monoclonal antibody immunofluorescence, deletion/point mutagenesis, premature chromosome condensation assay, leptomycin B treatment Molecular and cellular biology High 10330186
2000 14-3-3 binding regulates intracellular trafficking of CDC25C. CDC25C is actively exported from the nucleus via an intrinsic NES in its amino terminus. A 14-3-3-binding mutant of CDC25C is partially nuclear, and its nuclear accumulation is enhanced by leptomycin B. Loss of both NES function and 14-3-3 binding is required for complete nuclear accumulation. 14-3-3 binding negatively regulates nuclear import rather than promoting nuclear export.

2000 Human PLK directly phosphorylates CDC25C in vitro (using endogenous PLK immunoprecipitated from G2/M-arrested Jurkat cells and recombinant PLK). Phosphorylation of CDC25C by PLK activates its phosphatase activity, as assessed by dephosphorylation of cdc2-cyclin B.

2002 Hydrogen peroxide induces an intramolecular disulfide bond between the active-site cysteine (C377) and C330 in CDC25C in vitro, promoting its degradation in vivo. A double C330/C377 mutant that cannot form this disulfide is more stable, resistant to oxidative stress-induced degradation, and shows reduced 14-3-3 binding in vitro and in vivo. Chk1 phosphorylation site mutation did not prevent H2O2-induced degradation, indicating a Chk1-independent mechanism.

2004 Plk3 phosphorylates CDC25C primarily on S191 (and to a lesser extent S198) in vitro; both sites are within the nuclear exclusion motif. The S191D phosphomimetic mutant accumulates in the nucleus, whereas S191A facilitates nuclear exclusion. Plk3 overexpression promotes CDC25C nuclear accumulation and decreased Cdc2 Y15 phosphorylation; kinase-dead Plk3 fails to do so.

2007 ERK2/p42 MAPK is a major Cdc25C-phosphorylating kinase in M-phase-arrested Xenopus egg extracts. In Xenopus oocytes, p42 MAPK interacts with hypophosphorylated Cdc25C before meiotic induction and phosphorylates Cdc25C at T48, T138, and S205, increasing its phosphatase activity. In mammalian cells, ERK1/2 interacts with Cdc25C in interphase and phosphorylates Cdc25C at T48 in mitosis; ERK inhibition partially inhibits T48 phosphorylation, Cdc25C activation, and mitotic entry.

2002 Chk2 monomers and dimers both phosphorylate Cdc25C in vitro. Chk2 from unstressed cells is largely monomeric, inactive, and unphosphorylated at Thr-68. After DNA damage, active Chk2 exists as stable Thr-68-phosphorylated dimers as well as Thr-68-unphosphorylated monomers/dimers, all capable of phosphorylating Cdc25C.

2004 Pim-1 kinase directly binds and phosphorylates the N-terminal region of CDC25C, enhancing its phosphatase activity. Pim-1 also phosphorylates and inhibits C-TAK1 (which normally phosphorylates and inactivates CDC25C), thus indirectly activating CDC25C through two mechanisms.

2002 Arsenite induces CDC25C degradation via the ubiquitin-proteasome pathway. Mutation of the KEN box within residues 151–157 of CDC25C, or competition with a KEN-box peptide, partially inhibits arsenite-induced CDC25C ubiquitination.

2007 PP2A:B56δ dephosphorylates CDC25C both during interphase and at mitosis. Loss of PP2A:B56δ (stable knockdown or mouse KO) results in prolonged CDC25C hyperphosphorylation/activation and persistent Cdk1 activation, causing delayed mitotic exit. This is compensated by transcriptional upregulation of Wee1 kinase.

2001 Cdc25C knockout mice are viable, fertile, and display no obvious abnormalities. MEFs lacking Cdc25C show normal cdc2 phosphorylation, normal timing of mitotic entry, and normal DNA damage responses. This demonstrates Cdc25C is dispensable for embryonic and adult cell cycles in mice, suggesting functional redundancy with Cdc25A and/or Cdc25B.

2007 LZTS1/Fez1 interacts with Cdk1 and Cdc25C during mitosis. In Lzts1−/− MEFs, Cdc25C degradation is increased during M phase, resulting in decreased Cdk1 activity, accelerated mitotic progression, resistance to taxol/nocodazole-induced M-phase arrest, and improper chromosome segregation.

2012 Telomere damage (via TRF2 or POT1 depletion) activates ATR/ATM, which phosphorylate CHK1/CHK2, leading to S216 phosphorylation of CDC25C, its nuclear export, and proteasomal degradation. This CDC25C degradation is required to sustain G2/M arrest from dysfunctional telomeres. Additionally, p53 transcriptionally downregulates CDC25C in this context.

2017 Mdm2 physically interacts with CDC25C and promotes its proteasomal degradation in a ubiquitin-independent manner, reducing CDC25C half-life. Either Mdm2 overexpression or CDC25C downregulation delays cell cycle progression through G2/M. This is a p53-independent pathway, providing a dual mechanism (p53-mediated transcriptional repression + Mdm2-mediated protein degradation) for p53/Mdm2 to enforce G2/M arrest.

2015 During interphase, CDC25C phosphatase dephosphorylates phospho-Thr-838 in the activation loop of ASK1, suppressing ASK1-mediated apoptosis. CDC25C knockdown increases ASK1 activity; CDC25C overexpression inhibits ASK1-mediated apoptosis. During mitotic arrest, hyperphosphorylated CDC25C has reduced affinity for ASK1, allowing increased ASK1 activity. This reveals a cell cycle-dependent role for CDC25C in suppressing apoptosis during interphase.

2008 A fraction of CDC25C localizes to centrosomes in a cell cycle-dependent manner from late S phase through mitosis. CDC25C co-localizes with Cyclin B1 at centrosomes in G2 and prophase, and both undergo dynamic exchange between centrosome and cytoplasm (FRAP). Centrosomal localization is mediated by the catalytic C-terminal domain but does not require catalytic activity. Phosphatase-dead and substrate-binding mutants of CDC25C accumulate at centrosomes with phospho-Y15-Cdk1 and behave as dominant negatives that impair mitotic entry.

2010 Cyclin E/CDK2 physically interacts with and phosphorylates CDC25C on Ser214, leading to premature CDC25C activation. Low molecular weight (LMW) cyclin E overexpression causes premature inactivation of CDC25C and PLK1, leading to faster mitotic exit. Downregulation of CDC25C inhibits LMW-E-mediated chromosome missegregation, anaphase bridges, and centrosome amplification.

2015 p53-dependent repression of CDC25C requires activation of p21 (CDKN1A), which causes replacement of the MMB (B-MYB-MuvB) complex by the DREAM complex at CDE/CHR elements in the CDC25C promoter. ChIP shows E2F4 and p130 (DREAM components) replace B-MYB upon p53 activation; mutations in CDE/CHR elements abolish p53-dependent repression.
