AMP-activated protein kinase ?1 (AMPK?1) is a subunit of AMPK, a serine/threonine kinase that acts as a metabolic sensor to maintain cellular energy homeostasis.{59689} AMPK is a heterotrimeric complex composed of a catalytic ? subunit and ? and ? regulatory subunits, where each subunit has multiple isoforms encoded by different genes, forming up to 12 distinct heterotrimers. The ? subunit has two isoforms, ?1 and ?2, encoded by PRKAA1 and PRKAA2, respectively, in humans. AMPK?1 is ubiquitously expressed and contains an N-terminal kinase domain that is subject to phosphorylation, a modification required for its activation, as well as an auto-inhibitory domain connected to the C-terminal domain by a flexible ?-linker that associates with the ? subunit and regulates AMPK activity.{59689,59690} Under conditions of low intracellular ATP, such as hypoxia or nutrient deprivation, AMPK?1 is phosphorylated by liver kinase B1 (LKB1), leading to AMPK?1 activation and alterations in several key metabolic processes that restore energy homeostasis.{59691} AMPK?1 activation inhibits anabolic processes, such as glucose, lipid, or protein biosynthesis, activates catabolic processes, such as glycolysis, lipolysis, and autophagy, and stimulates mitochondrial biogenesis and lysosomal degradation. Cayman's AMPK?1 Rabbit Monoclonal Antibody can be used for immunohistochemistry (IHC) and Western blot (WB) applications.
