PRKAB1
5'-AMP-activated protein kinase subunit beta-1 is an enzyme that in humans is encoded by the PRKAB1 gene.[5][6]

Model organisms have been used in the study of PRKAB1 function. A conditional knockout mouse line, called Prkab1tm1a(KOMP)Wtsi[14][15] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.[16][17][18]
Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[12][19] Twenty five tests were carried out on mutant mice and four significant abnormalities were observed.[12] Homozygous mutant males displayed impaired glucose tolerance. Animals of both sex had increased circulating bilirubin levels, increased IgG3 levels, and a number of atypical haematology parameters.[12]
Interactions
PRKAB1 has been shown to interact with PRKAG2[20] and PRKAG1.[20]
The 5'-AMP-activated protein kinase beta subunit interaction domain (AMPKBI) is a conserved domain found in the beta subunit of the 5-AMP-activated protein kinase complex, and its yeast homologues Sip1, Sip2 and Gal83, which are found in the SNF1 kinase complex.[21] This region is sufficient for interaction of this subunit with the kinase complex, but is not solely responsible for the interaction, and the interaction partner is not known.[22]
