PRKAR2A encodes the human gene, Protein kinase, cAMP-dependent, regulatory subunit type II alpha. It may also be known as: cAMP-dependent protein kinase type II-alpha regulatory subunit; PKR2; protein kinase, cAMP-dependent, regulatory, type II, alpha. The encoded protein has an amino acid length of 404 and a mass of 45.5 kDa. PRKAR2A is a member of the CAMP-dependent kinase regulatory chain family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
