RPS6KA5

Ribosomal protein S6 kinase alpha-5 is an enzyme that in humans is encoded by the "RPS6KA5" gene. This kinase, together with RPS6KA4, are thought to mediate the phosphorylation of histone H3, linked to the expression of immediate early genes. 
Interactions.
RPS6KA5 has been shown to interact with CREB1.
