Prkar2a Gene Summary [Rat]
Enables several functions, including beta-2 adrenergic receptor binding activity; cAMP binding activity; and cAMP-dependent protein kinase regulator activity. Involved in regulation of protein kinase activity. Located in T-tubule and perinuclear region of cytoplasm. Part of cAMP-dependent protein kinase complex. Human ortholog(s) of this gene implicated in congestive heart failure. Orthologous to human PRKAR2A (protein kinase cAMP-dependent type II regulatory subunit alpha).

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 Prkar2a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
