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 and CC inhibits energy-consuming processes: inhibits protein, carbohydrate and CC lipid biosynthesis, as well as cell growth and proliferation. AMPK acts CC via direct phosphorylation of metabolic enzymes, and by longer-term CC effects 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. Gamma non-catalytic subunit CC mediates binding to AMP, ADP and ATP, leading to activate or inhibit CC AMPK: 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 stimulates CC phosphorylation, without stimulating already phosphorylated catalytic CC subunit. ATP promotes dephosphorylation of catalytic subunit, rendering CC the AMPK enzyme inactive (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). Interacts with FNIP1 and FNIP2 (By CC 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 around CC sites phosphorylated on target proteins of AMPK, except the presence of CC a non-phosphorylatable residue in place of Ser. In the absence of AMP CC this pseudosubstrate sequence may bind to the active site groove on the CC alpha subunit (PRKAA1 or PRKAA2), preventing phosphorylation by the CC upstream activating kinase STK11/LKB1 (By similarity). {ECO:0000250}. CC -!- DOMAIN: The 4 CBS domains mediate binding to nucleotides. Of the 4 CC potential nucleotide-binding sites, 3 are occupied, designated as sites CC 1, 3, and 4 based on the CBS modules that provide the acidic residue CC for coordination with the 2'- and 3'-hydroxyl groups of the ribose of CC AMP. Of these, site 4 appears to be a structural site that retains a CC tightly held AMP molecule (AMP 3). The 2 remaining sites, 1 and 3, can CC bind either AMP, ADP or ATP. Site 1 (AMP, ADP or ATP 1) is the high- CC affinity binding site and likely accommodates AMP or ADP. Site 3 (AMP, CC ADP or ATP 2) is the weakest nucleotide-binding site on the gamma CC subunit, yet it is exquisitely sensitive to changes in nucleotide CC levels and this allows AMPK to respond rapidly to changes in cellular CC energy status. Site 3 is likely to be responsible for protection of a CC conserved threonine in the activation loop of the alpha catalytic CC subunit through conformational changes induced by binding of AMP or CC ADP. {ECO:0000250|UniProtKB:P80385}. CC -!- PTM: Phosphorylated by ULK1; leading to negatively regulate AMPK CC activity and suggesting the existence of a regulatory feedback loop CC between ULK1 and AMPK. {ECO:0000269|PubMed:21460634}. CC -!- SIMILARITY: Belongs to the 5'-AMP-activated protein kinase gamma CC subunit family. {ECO:0000305}.
