PRKAA is an alias for the gene, Protein kinase, AMP-activated, alpha 2 catalytic subunit, in humans. Other names include: 5'-AMP-activated protein kinase catalytic subunit alpha-2; AMPK subunit alpha-2; AMPK; AMPK2; AMPKa2. The encoded protein is an enzyme with an amino acid length of 552 and a mass of 62.3 kDa. PRKAA is a member of the Protein kinase superfamily, CAMK Ser/Thr protein kinase family, SNF1 subfamily. This gene shares homology with other species, including: Frog.
