RPS6
Description
The RPS6 (ribosomal protein S6) is a protein-coding gene located on chromosome 9.
Ribosomal protein S6 (rpS6 or eS6) is a component of the 40S ribosomal subunit and is therefore involved in translation. Mouse model studies have shown that phosphorylation of eS6 is involved in the regulation of cell size, cell proliferation, and glucose homeostasis. Studies show that the p70 ribosomal protein S6 kinases (S6K1 and S6K2) and p90 ribosomal protein S6 kinases (RSK) both phosphorylate eS6 and that S6K1 and S6K2 predominate this function. Pathways leading to the induction of human eS6 phosphorylation have been found to enhance IL-8 protein synthesis. This mechanism is dependent on A/U-rich proximal sequences (APS) found in the 3'UTR of IL-8 immediately after the stop codon.
Component of the 40S small ribosomal subunit (PubMed:8706699, PubMed:23636399). Plays an important role in controlling cell growth and proliferation through the selective translation of particular classes of mRNA (PubMed:17220279). Part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit. During the assembly of the SSU processome in the nucleolus, many ribosome biogenesis factors, an RNA chaperone and ribosomal proteins associate with the nascent pre-rRNA and work in concert to generate RNA folding, modifications, rearrangements and cleavage as well as targeted degradation of pre-ribosomal RNA by the RNA exosome (PubMed:34516797).
RPS6 is also known as S6, eS6.
