Summary: Predicted to enable several functions, including beta-2 adrenergic receptor binding activity; cAMP binding activity; and enzyme binding activity. Involved in modulation of chemical synaptic transmission. Located in cytoplasm. Part of cAMP-dependent protein kinase complex. Is active in glutamatergic synapse. Is expressed in several structures, including alimentary system; brain; eye; genitourinary system; and leg. Human ortholog(s) of this gene implicated in congestive heart failure. Orthologous to human PRKAR2A (protein kinase cAMP-dependent type II regulatory subunit alpha). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
