PRKAA1 encodes the human gene, Protein kinase, AMP-activated, alpha 1 catalytic subunit. It may also be known as: 5'-AMP-activated protein kinase catalytic subunit alpha-1; Tau-protein kinase PRKAA1; AMPK subunit alpha-1; AMPK, alpha, 1; AMPKa1. The encoded protein is an enzyme with an amino acid length of 559 and a mass of 64.0 kDa. PRKAA1 is a member of the Protein kinase superfamily, CAMK Ser/Thr protein kinase family, SNF1 subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
