RPS6KA3
Enzyme found in humans
From Wikipedia, the free encyclopedia
protein S6 kinase, 90kDa, polypeptide 3, also s RPS6KA3, is an enzyme that in humans is encoded by the RPS6KA3 gene.[5][6]

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.[5]
Clinical significance
Mutations in this gene have been associated with Coffin–Lowry syndrome (CLS).[7]
