Cyclic AMP-Dependent Protein Kinase RIalpha Subunit (Protein Kinase A, RIalpha Subunit)
A type I 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 RIBETA SUBUNIT.
