Ribosomal protein S6 kinase, 90kDa, polypeptide 3, also known as RPS6KA3, is an enzyme that in humans is encoded by the RPS6KA3 gene.[1][2]

Function

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.[1]

Clinical significance

Mutations in this gene have been associated with Coffin-Lowry syndrome (CLS).[3]

Interactions

RPS6KA3 has been shown to interact with CREB-binding protein,[4] MAPK1[5][6] and PEA15.[7]
