Related Product Information for PRKAB1 recombinant protein

Description: PRKAB1 Human Recombinant produced in E Coli is a single, non-glycosylated, polypeptide chain containing 293 amino acids (1-270 a.a.) and having a molecular mass of 32.8 kDa. The PRKAB1 is fused to a 23 amino acid His Tag at N-Terminus and purified by proprietary chromatographic techniques.

Introduction: 5'-AMP-activated protein kinase subunit beta-1 (PRKAB1) hinders protein, carbohydrate and lipid biosynthesis, in addition to cell growth and proliferation. AMPK is a heterotrimer comprised of an alpha catalytic subunit, and non-catalytic beta and gamma subunits. AMPK acts via direct phosphorylation of metabolic enzymes, and longer-term effects by phosphorylation of transcription regulators. PRKAB1 is a regulator of cellular polarity by remodeling the actin cytoskeleton; most likely by indirectly activating myosin. Beta non-catalytic subunit acts as a scaffold on which the AMPK complex compiles, through its C-terminus that joins alpha (PRKAA1 or PRKAA2) and gamma subunits (PRKAG1, PRKAG2 or PRKAG3).

NCBI Description

The protein encoded by this gene is a regulatory subunit of the AMP-activated protein kinase (AMPK). AMPK is a heterotrimer consisting of an alpha catalytic subunit, and non-catalytic beta and gamma subunits. AMPK is an important energy-sensing enzyme that monitors cellular energy status. In response to cellular metabolic stresses, AMPK is activated, and thus phosphorylates and inactivates acetyl-CoA carboxylase (ACC) and beta-hydroxy beta-methylglutaryl-CoA reductase (HMGCR), key enzymes involved in regulating de novo biosynthesis of fatty acid and cholesterol. This subunit may be a positive regulator of AMPK activity. The myristoylation and phosphorylation of this subunit have been shown to affect the enzyme activity and cellular localization of AMPK. This subunit may also serve as an adaptor molecule mediating the association of the AMPK complex. [provided by RefSeq, Jul 2008]

Uniprot Description

AMPKB1: a non-catalytic subunit of AMPK, a conserved kinase of the CAMKL family. AMPK is an energy-sensing protein that plays a key role in regulating cellular energy homeostasis. Environmental stress, such as heat shock, nutrient deprivation, hypoxia and ischemia, indirectly activate AMPK by the depletion of cellular ATP and the concomitant rise of ADP and AMP levels. Allosteric activation is achieved primarily by rising ADP levels, and not solely by AMP levels as previously thought. Activates energy-producing pathways and inhibits energy-consuming processes: inhibits protein, carbohydrate and lipid biosynthesis, as well as cell growth and proliferation. AMPK acts via direct phosphorylation of metabolic enzymes, and by longer-term effects via phosphorylation of transcription regulators. Also acts as a regulator of cellular polarity by remodeling the actin cytoskeleton, probably by indirectly activating myosin. AMPK is a heterotrimer of an alpha catalytic subunit (AMPKA1 or -2), a beta (AMPKB1 or -2) and a gamma non-catalytic subunit (AMPKG1, -2 or -3). Different possible combinations of subunits give rise to 12 different holoenzymes. Beta subunits act as scaffolds on which the AMPK complex assembles, via its C-terminus that bridges alpha and gamma subunits. AMPK-beta1 or -beta2 subunits are required for assembling of AMPK heterotrimers and are important for regulating enzyme activity and cellular localization. AMPK beta1beta2 null mouse muscles reveal an essential role for AMPK in maintaining mitochondrial content and glucose uptake during exercise. Phosphorylation by ULK1 and ULK2 inhibits AMPK activity. Hematopoietic AMPKB1 reduces mouse adipose tissue macrophage inflammation and insulin resistance in obesity.
