Synthesis pass · prose summary of the discoveries below

RPLP1 is an acidic phosphoprotein of the 60S ribosomal subunit stalk that functions in translation elongation and selective translational regulation. It assembles specifically into the large ribosomal subunit via its conserved C-terminal domain shared with P0 and P2, forming a stalk complex analogous to bacterial L7/L12–L10 that coordinates elongation factor interactions (PMID:3323886, PMID:23636399). RPLP1 relieves ribosome pausing at mRNA sequences encoding multi-pass transmembrane domains, facilitating co-translational folding and protein stability, and is particularly critical for flavivirus polyprotein translation (PMID:32890404, PMID:27974556). Genetic ablation in mice does not impair global protein synthesis but selectively alters translation of cell cycle, stress-response, and protein-folding transcripts, causing CNS-specific progenitor cell death and perinatal lethality, while overexpression drives E2F1/cyclin E–dependent proliferation and cooperates with oncogenic Ras in cellular transformation (PMID:24959908, PMID:19233166).

1987 Human acidic ribosomal phosphoprotein P1 (RPLP1) was identified and its cDNA cloned. RPLP1 shares a nearly identical carboxy-terminal 17-amino-acid sequence (KEESEESD(D/E)DMGFGLFD-COOH) with P0 and P2, explaining their immunological cross-reactivity. In vitro synthesized RPLP1 assembled specifically into 60S but not 40S ribosomes and formed a complex analogous to bacterial L7/L12 and L10, indicating RPLP1 is part of the large ribosomal subunit stalk. cDNA cloning, in vitro transcription/translation, immunoprecipitation, ribosome assembly assay Molecular and cellular biology High 3323886
1995 Mammalian ribosomal protein RPLP1 (P1) was structurally characterized as an acidic phosphoprotein homologous to bacterial L7/L12; it is located in the 60S ribosomal subunit stalk and its mRNA carries a terminal oligopyrimidine (TOP) tract characteristic of ribosomal protein mRNAs, linking translational regulation to ribosome biogenesis. Amino acid sequencing, sequence comparison, structural analysis of ribosomal proteins Biochemistry and cell biology Medium 8722009
2007 The RPLP1 gene and protein are highly conserved across mammals (human, mouse, rat, bovine, porcine, and giant panda), with >88% amino acid sequence identity. The protein contains Casein kinase II phosphorylation sites and N-myristoylation sites. Recombinant His-tagged RPLP1 was expressed in E. coli as an ~18 kDa polypeptide consistent with the predicted molecular weight. RT-PCR cDNA cloning, sequence analysis, prokaryotic overexpression International journal of biological sciences Low 18071584
2009 Overexpression of Rplp1 in primary mouse embryonic fibroblasts (MEFs) bypassed replicative senescence, produced a two-fold increase in E2F1 promoter activity, and upregulated cyclin E. Co-expression of Rplp1 with mutant Ras (RasVal12) caused oncogenic transformation of NIH3T3 cells as demonstrated by soft-agar colony formation, establishing Rplp1 as a driver—not merely a consequence—of cell proliferation. Retroviral cDNA library screen, promoter-reporter assay, soft-agar transformation assay, western blot, MEF immortalization assay Experimental cell research Medium 19233166
2013 Cryo-EM structures of the human and Drosophila 80S ribosomes revealed the architectural position of ribosomal stalk proteins including RPLP1 within the large subunit, showing their co-evolution with metazoan-specific ribosomal RNA and their role in forming the stalk structure that coordinates translation elongation factor interactions. High-resolution cryo-electron microscopy, atomic model building Nature High 23636399
2014 Germline disruption of Rplp1 in mice caused body size reduction, male infertility, and high rates of early postnatal death, while CNS-specific deletion (Rplp1CNSΔ) resulted in perinatal lethality and brain atrophy with reduced neocortex, midbrain, and ganglionic eminence. Rplp1 knockout neocortex exhibited progenitor cell proliferation arrest and apoptosis with dysregulation of cyclin A, cyclin E, p21CIP1, p27KIP1, and p53. Deletion in primary MEFs caused proliferation arrest and premature senescence. Importantly, Rplp1 deletion did not alter global protein synthesis but changed expression of specific protein subsets involved in protein folding, unfolded protein response, and cell death, indicating a 'translational fine-tuning' role. Conditional and germline mouse knockout, immunohistochemistry, flow cytometry, western blot, 2D-DIGE proteomics, histology PloS one High 24959908
2015 Near-atomic resolution cryo-EM structure of the human 80S ribosome (average 3.6 Å, best 2.9 Å) was determined, providing atomic-level detail of the ribosomal stalk where RPLP1 resides, including visualization of rRNA entities, amino acid side chains, tRNA binding sites, and subunit interface remodeling during ribosomal rotation. Single-particle cryo-electron microscopy, atomic model building Nature High 25901680
2017 RPLP1 and RPLP2 (RPLP1/2) were identified as essential host factors for dengue virus (DENV), yellow fever virus (YFV), and Zika virus (ZIKV) infection. Knockdown of RPLP1/2 strongly reduced early DENV protein accumulation and reduced DENV structural proteins expressed from an exogenous transgene, indicating a requirement specifically at the translation step. While RPLP1/2 depletion caused only modest and cell-line-specific effects on global protein synthesis (increased in A549, decreased in HuH-7), it strongly impaired viral translation elongation through the viral open reading frame, consistent with their known role in orchestrating translation elongation via the ribosomal stalk. Genome-scale RNAi screen, siRNA knockdown, metabolic labeling, viral infection assay in two human cell lines and Aedes aegypti mosquitoes, transgene expression assay Journal of virology High 27974556
2020 RPLP1/2 relieve ribosome pausing within the dengue virus envelope protein coding sequence, specifically at sequences encoding the N-terminus of the envelope protein immediately downstream of two adjacent transmembrane domains (TMDs). Ribosome profiling of RPLP1/2-depleted cells showed increased ribosome pausing at this region and disproportionate effects on mRNAs encoding multiple TMDs, implying a general role for RPLP1/2 in facilitating elongation through multi-pass transmembrane protein-coding sequences, likely by improving co-translational folding efficiency and subsequent protein stability. siRNA knockdown, ribosome profiling (Ribo-seq), protein stability assays, bioinformatic analysis of TMD-containing mRNAs Nucleic acids research High 32890404
2020 CNN3 (calponin 3) promotes cervical cancer cell viability and motility partly through upregulation of RPLP1 mRNA expression, as demonstrated by RNA sequencing identifying RPLP1 as a downstream target of CNN3, and rescue experiments showing that RPLP1 overexpression partially reverses the phenotypes inhibited by CNN3 silencing, placing RPLP1 downstream of CNN3 in a pro-tumorigenic pathway. siRNA knockdown, RNA-seq, qRT-PCR, proliferation/migration/invasion assays, xenograft mouse model, rescue overexpression experiments Scientific reports Medium 32051425
