cAMP Protein Kinase RIIbeta

A type II cAMP-Dependent Protein Kinase regulatory subunit that plays a Role in confering Cyclic AMP activation of Protein Kinase Activity. It has a lower affinity for cAMP than the Cyclic-AMP-Dependent Protein Kinase RIIalpha Subunit. Binding of this subunit by A Kinase Anchor Proteins may play a Role in the cellular localization of type II Protein Kinase A.
