NCIt definition : Ribosomal protein S6 kinase beta-2 (482 aa, 53 kDa) is encoded by the human RPS6KB2
gene. This protein is involved in serine/threonine protein phosphorylation.;
NCIt note : Ribosomal Protein S6 Kinase Beta 2 specifically phosphorylates 40S ribosomal protein
S6, the major eukaryotic ribosome substrate of many kinases. S6 phosphorylation is
stimulated by growth factors and mitogens; dephosphorylation occurs at growth arrest.
S6 may control cell growth and proliferation through the selective translation of
specific of mRNA classes.;
