CC -!- FUNCTION: Non-catalytic subunit of AMP-activated protein kinase (AMPK), CC an energy sensor protein kinase that plays a key role in regulating CC cellular energy metabolism. In response to reduction of intracellular CC ATP levels, AMPK activates energy-producing pathways and inhibits CC energy-consuming processes: inhibits protein, carbohydrate and lipid CC biosynthesis, as well as cell growth and proliferation. AMPK acts via CC direct phosphorylation of metabolic enzymes, and by longer-term effects CC via phosphorylation of transcription regulators. Also acts as a CC regulator of cellular polarity by remodeling the actin cytoskeleton; CC probably by indirectly activating myosin. Beta non-catalytic subunit CC acts as a scaffold on which the AMPK complex assembles, via its C- CC terminus that bridges alpha (PRKAA1 or PRKAA2) and gamma subunits CC (PRKAG1, PRKAG2 or PRKAG3) (By similarity). {ECO:0000250}. CC -!- SUBUNIT: AMPK is a heterotrimer of an alpha catalytic subunit (PRKAA1 CC or PRKAA2), a beta (PRKAB1 or PRKAB2) and a gamma non-catalytic CC subunits (PRKAG1, PRKAG2 or PRKAG3). {ECO:0000250}. CC -!- PTM: Phosphorylated when associated with the catalytic subunit (PRKAA1 CC or PRKAA2). Phosphorylated by ULK1 and ULK2; leading to negatively CC regulate AMPK activity and suggesting the existence of a regulatory CC feedback loop between ULK1, ULK2 and AMPK. CC {ECO:0000269|PubMed:21460634}. CC -!- SIMILARITY: Belongs to the 5'-AMP-activated protein kinase beta subunit CC family. {ECO:0000305}.
