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