Ribosomal protein S6 kinase alpha-2 is an enzyme that in humans is encoded by the RPS6KA2 gene.^[5]^[6]

This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine and 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. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.^[6]

Interactions

RPS6KA2 has been shown to interact with MAPK3^[7]^[8] and MAPK1.^[7]^[8]
