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.
