Predicted to enable cAMP-dependent protein kinase inhibitor activity and protein kinase A catalytic subunit binding activity. Predicted to be involved in negative regulation of cAMP-dependent protein kinase activity. Predicted to act upstream of or within negative regulation of nitrogen compound metabolic process; negative regulation of protein import into nucleus; and regulation of G2/M transition of mitotic cell cycle. Predicted to be active in cytoplasm and nucleus. Orthologous to human PKIA (cAMP-dependent protein kinase inhibitor alpha). [provided by Alliance of Genome Resources, Apr 2022]
