PCTK1

Serine/threonine-protein kinase PCTAIRE-1 is an enzyme that in humans is encoded by the "PCTK1" gene.
Function.
The protein encoded by this gene belongs to the cdc2/cdkx subfamily of the ser/thr family of protein kinases. It may play a role in signal transduction cascades in terminally differentiated cells. This gene is thought to escape X inactivation. Two transcript variants encoding the same protein have been found for this gene.
Interactions.
PCTK1 has been shown to interact with CDK5R1.
