p39 Polyclonal Antibody

Cyclin dependent kinase 5 regulatory subunit 2 encoded by CDK5R2 is a neuron-specific activator of CDK5 kinase. It associates with CDK5 to form an active kinase. Cyclin dependent kinase 5 regulatory subunit 2 and neuron-specific CDK5 activator CDK5R1/p39NCK5A both share limited similarity to cyclins, and thus may define a distinct family of cyclin-dependent kinase activating proteins.
