This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains 2 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. Mutations in this gene have been associated with Coffin-Lowry syndrome (CLS).
FUNCTION: SwissProt: P51812 # Serine/threonine kinase that may play a role in mediating the growth-factor and stress induced activation of the transcription factor CREB. COFACTOR: Magnesium (By similarity). SIZE: 740 amino acids; 83736 Da SUBUNIT: Forms a complex with either ERK1 or ERK2 in quiescent cells. Transiently dissociates following mitogenic stimulation (By similarity). TISSUE SPECIFICITY: Expressed in many tissues, highest levels in skeletal muscle. PTM: Autophosphorylated on Ser-386, as part of the activation process (By similarity). & Ser-227 phosphorylation promotes Ser-386 phosphorylation and leads to basal activation. Full activation by growth factors requires additional phosphorylation on Ser-369 (By similarity). DISEASE: SwissProt: P51812 # Defects in RPS6KA3 are the cause of Coffin-Lowry syndrome (CLS) [MIM:303600]; an X-linked dominant disorder characterized by severe mental retardation with facial and digital dysmorphisms, and progressive skeletal deformations. SIMILARITY: SwissProt: P51812 ## Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. S6 kinase subfamily. & Contains 1 AGC-kinase C-terminal domain. & Contains 2 protein kinase domains.
