Cyclin Dependent Kinase 16 (CDK16)

CDK16 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.

The 3 PCTAIRE kinases are 65% identical to one another (80% within the catalytic domain). PCTAIRE1 is ubiquitously expressed with the highest levels detected in the brain and testis. Human PCTAIRE cDNAs do not complement yeast cdc28 mutants and show other differences, suggesting that PCTAIRE kinases have different cellular functions from those described for CDC2.
