Pkia Gene Summary [Rat]
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/PKA signal transduction. Predicted to act upstream of or within negative regulation of macromolecule 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, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Pkia often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
