Ribosomes (the organelles that catalyze protein synthesis) consist of a small 40S subunit and a large 60S subunit. Jointly these subunits are composed of 4 RNA species and approximately 80 structurally distinct proteins. RPS10 which is is located in the cytoplasm and a part of the S10E family of ribosomal proteins, is a ribosomal protein that is a component of the 40S subunit. Variable expression of this gene in colorectal cancers compared to adjacent normal tissues has been observed, although no correlation between the level of expression and the severity of the disease has been found.
Post-translational: Methylated by PRMT5. Methylation is necessary for its interaction with NPS1, its localization in the granular component (GC) region of the nucleolus, for the proper assembly of ribosomes, protein synthesis and optimal cell proliferation. Monoubiquitinated by ZNF598 when a ribosome has stalled during translation of poly(A) sequences, leading to preclude synthesis of a long poly-lysine tail and initiate the ribosome quality control (RQC) pathway to degrade the potentially detrimental aberrant nascent polypeptide (PubMed:28065601, PubMed:28132843, PubMed:28685749, PubMed:32011234, PubMed:36302773). Deubiquitinated by OTUD3 and USP21, antagonizing ZNF598 activity (PubMed:32011234). Deubiquitinated by OTUD1, antagonizing ZNF598 activity and stimulating formation of polysomes: deubiquitination by OTUD1 promotes stability and translation of a subset mRNAs with a high abundance of rare codons can limit the translation rate (PubMed:36445135). Deubiquitinated by USP10 (PubMed:31981475).
