RPS6KA4

Ribosomal protein S6 kinase alpha-4 is an is_associated_with::enzyme that in humans is encoded by the RPS6KA4 is_associated_with::gene.

Function
This gene encodes a member of the RSK (is_associated_with::ribosomal S6 kinase) family of is_associated_with::serine/threonine kinases. This kinase contains 2 non-identical kinase catalytic domains and is_associated_with::phosphorylates various substrates, including is_associated_with::CREB1 and is_associated_with::c-Fos. Alternate transcriptional splice variants of this gene have been observed but have not been thoroughly characterized.

Interactions
RPS6KA4 has been shown to interact with is_associated_with::MAPK14.
