PRKAB1 encodes the human gene, Protein kinase, AMP-activated, beta 1 non-catalytic subunit. It may also be known as: 5'-AMP-activated protein kinase subunit beta-1; AMPKb; AMPK subunit beta-1; AMPK beta 1; HAMPKb. The encoded protein has an amino acid length of 270 and a mass of 30.4 kDa. Other isoforms may exist. PRKAB1 is a member of the 5'-AMP-activated protein kinase beta subunit family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
