RPS6KA2(ribosomal protein S6 kinase A2) encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains two non-identical kinase catalytic domains and phosphorylates various substrates, including members of the mitogen-activated kinase (MAPK) signalling pathway. The activity of this protein has been implicated in controlling cell growth and differentiation. Alternative splice variants, encoding different isoforms, have been characterized.蛋白别名为:RPS6KA2 MAPKAPK1C RSK3;基因ID为:6196;蛋白质ID:Q15349
