Ribosomal protein S6 kinase alpha-1 is an enzyme that in humans is encoded by the RPS6KA1 gene.^[1]

This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains 2 nonidentical 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. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.^[2]

[edit] Interactions

RPS6KA1 has been shown to interact with YWHAB,^[3] MAPK1,^[4]^[5]^[6] IκBα,^[7] TOB1^[8] and TSC2.^[9]^[10]
