RPS6KA3
| View/Edit Human | View/Edit Mouse |
Ribosomal protein S6 kinase, 90kDa, polypeptide 3, also known as RPS6KA3, is an enzyme that in humans is encoded by the RPS6KA3 gene.[3][4]
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.[3]
Clinical significance
Mutations in this gene have been associated with Coffin–Lowry syndrome (CLS).[5]
Interactions
RPS6KA3 has been shown to interact with CREB-binding protein,[6] MAPK1[7][8] and PEA15.[9]
