AMPK (G1/B2/A2) Heterotrimer Protein Product Information
||AMPK, 5' AMP-activated protein kinase, 5' adenosine monophosphate-activated protein kinase. Heterotrimer of alpha 2 catalytic subunit, beta 2 non-catalytic subunit and gamma 1 non-catalytic subunit.
A DNA sequence encoding the human PRKAG1 (P54619) (Met 1-Pro 331), constructed the plasmid 1; A DNA sequence encoding the human PRKAB2 (O43741) (Met 1-Ile 272), constructed the plasmid 2.; A DNA sequence encoding the human PRKAA2 (P54646) (Met 1-Arg 552) was fused with the N-terminal polyhistidine-tagged GST tag at the N-terminus, constructed the plasmid 3. The three plasmids were co-expressed and the heterotrimer was purified.

AMPK (G1/B2/A2) Heterotrimer Protein Description
AMP-activated protein kinase (AMPK) is an important metabolic stress-sensing protein kinase induced by AMP. It can be detected in a number of tissues, including the liver, brain, and skeletal muscle. AMPK is a heterotrimer comprised by three proteins (α, β, and γ subunits) that together make a functional enzyme, conserved from yeast to humans. Seven known genes encode the subunit isoforms (α1, α2, β1, β2, γ1, γ2, γ3) and all are expressed in the heart. The most common isoforms expressed in most cells are the α1(PRKAA1), β1(PRKAB1), and γ1(PRKAG1) isoforms. AMPK induces a cascade of events within cells in response to the ever changing energy charge of the cell. Mammalian AMPK is a stable alphabetagamma heterotrimer comprising a catalytic alpha (PRKAA) and two non-catalytic subunits, beta (PRKAB) and gamma (PRKAG). AMPK activation results in the stimulation of hepatic fatty acid oxidation and ketogenesis, inhibition of cholesterol synthesis, lipogenesis, and triglyceride synthesis, inhibition of adipocyte lipolysis and lipogenesis, stimulation of skeletal muscle fatty acid oxidation and muscle glucose uptake, and modulation of insulin secretion by pancreatic beta-cells.
