cAMP Protein Kinase RIIalpha

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 higher affinity for cAMP than that of the Cyclic-AMP-Dependent Protein Kinase RIIbeta Subunit. Binding of this subunit by A Kinase Anchor Proteins may play a Role in the cellular localization of type II Protein Kinase A.
