RPS6KA3
Ribosomal protein S6 kinase, 90kDa, polypeptide 3, also known as RPS6KA3, is an enzyme that in humans is encoded by the RPS6KA3 gene.Function
This gene encodes a member of the RSK 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 signalling pathway. The activity of this protein has been implicated in controlling cell growth and differentiation.Clinical significance
Mutations in this gene have been associated with Coffin–Lowry syndrome.Interactions
RPS6KA3 has been shown to interact with CREB-binding protein, MAPK1 and PEA15.
