CC -!- FUNCTION: AMP/ATP-binding 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. Gamma non-catalytic subunit mediates CC binding to AMP, ADP and ATP, leading to activate or inhibit AMPK: CC AMP-binding results in allosteric activation of alpha catalytic CC subunit (PRKAA1 or PRKAA2) both by inducing phosphorylation and CC preventing dephosphorylation of catalytic subunits. ADP also CC stimulates phosphorylation, without stimulating already CC phosphorylated catalytic subunit. ATP promotes dephosphorylation CC of catalytic subunit, rendering the AMPK enzyme inactive (By CC similarity). {ECO:0000250}. 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). Interacts with CC FNIP1 and FNIP2 (By similarity). {ECO:0000250}. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Name=A; CC IsoId=Q91WG5-1; Sequence=Displayed; CC Name=B; CC IsoId=Q91WG5-2; Sequence=VSP_015586; CC -!- DOMAIN: The AMPK pseudosubstrate motif resembles the sequence CC around sites phosphorylated on target proteins of AMPK, except the CC presence of a non-phosphorylatable residue in place of Ser. In the CC absence of AMP this pseudosubstrate sequence may bind to the CC active site groove on the alpha subunit (PRKAA1 or PRKAA2), CC preventing phosphorylation by the upstream activating kinase CC STK11/LKB1 (By similarity). {ECO:0000250}. CC -!- DOMAIN: The CBS domains mediate binding to AMP, ADP and ATP. 2 CC sites bind either AMP or ATP, whereas a third site contains a CC tightly bound AMP that does not exchange. Under physiological CC conditions AMPK mainly exists in its inactive form in complex with CC ATP, which is much more abundant than AMP (By similarity). CC {ECO:0000250}. CC -!- PTM: Phosphorylated by ULK1; leading to negatively regulate AMPK CC activity and suggesting the existence of a regulatory feedback CC loop between ULK1 and AMPK. {ECO:0000269|PubMed:21460634}. CC -!- SIMILARITY: Belongs to the 5'-AMP-activated protein kinase gamma CC subunit family. {ECO:0000305}. CC -!- SIMILARITY: Contains 4 CBS domains. {ECO:0000255|PROSITE- CC ProRule:PRU00703}.
