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]
PRKAB1 (Protein Kinase AMP-Activated Non-Catalytic Subunit Beta 1) is a Protein Coding gene. Diseases associated with PRKAB1 include Fatty Liver Disease and Hyperglycemia. Among its related pathways are Organelle biogenesis and maintenance and Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins.. Gene Ontology (GO) annotations related to this gene include protein kinase activity and AMP-activated protein kinase activity. An important paralog of this gene is PRKAB2.
AMP-activated protein kinase (AMPK) is a heterodimeric protein serine/threonine kinase that is composed of alpha- (catalytic) and beta/gamma- (regulatory) subunits. AMPK acts as a sensor of the energy status of cells and ensures survival during times of cellular metabolic stress.
