The protein encoded by this gene is a member of the cAMP-dependent protein kinase (PKA) inhibitor family. This protein was demonstrated to interact with and inhibit the activities of both C alpha and C beta catalytic subunits of the PKA. Alternatively spliced transcript variants encoding the same protein have been reported.
cAMP-dependent protein kinase inhibitor alpha; cAMP-dependent protein kinase inhibitor, muscle/brain isoform; PKI-alpha; PRKACN1; protein kinase inhibitor, alpha
