Anti-PRKAB1 antibodies are used in the immunodetection of the protein protein kinase AMP-activated non-catalytic subunit beta 1. In humans, the canonical protein has a reported length of 270 amino acid residues and a mass of 30.4 kDa. It is notably widely expressed in many tissue types. A member of the 5'-AMP-activated protein kinase beta subunit protein family, PRKAB1 is reported to be a non-catalytic subunit of AMP-activated protein kinase (AMPK), an energy sensor protein kinase that plays a key role in regulating cellular energy metabolism. Synonyms for this target antigen include HAMPKb, 5'-AMP-activated protein kinase subunit beta-1, 5'-AMP-activated protein kinase beta-1 subunit, AMP-activated protein kinase beta subunit, AMPK beta -1 chain, and AMPK. PRKAB1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 190 citations in the literature describe the use of PRKAB1 antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
