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

Function

[edit]

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

[edit]

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

Interactions

[edit]

RPS6KA3 has been shown to interact with CREB-binding protein,[8] MAPK1[9][10] and PEA15.[11]
