Prkar2b Gene Summary [Rat]
Enables cAMP binding activity; cAMP-dependent protein kinase regulator activity; and protein domain specific binding activity. Involved in regulation of protein kinase activity and response to antipsychotic drug. Located in dendrite; neuronal cell body; and perinuclear region of cytoplasm. Part of cAMP-dependent protein kinase complex. Orthologous to human PRKAR2B (protein kinase cAMP-dependent type II regulatory subunit beta). [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 Prkar2b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
