CC -!- FUNCTION: Catalytic subunit of AMP-activated protein kinase (AMPK), an
CC energy sensor protein kinase that plays a key role in regulating
CC cellular energy metabolism (PubMed:14511394). In response to reduction
CC of intracellular ATP levels, AMPK activates energy-producing pathways
CC and inhibits energy-consuming processes: inhibits protein, carbohydrate
CC and lipid biosynthesis, as well as cell growth and proliferation (By
CC similarity). AMPK acts via direct phosphorylation of metabolic enzymes,
CC and by longer-term effects via phosphorylation of transcription
CC regulators (By similarity). Regulates lipid synthesis by
CC phosphorylating and inactivating lipid metabolic enzymes such as ACACA,
CC ACACB, GYS1, HMGCR and LIPE; regulates fatty acid and cholesterol
CC synthesis by phosphorylating acetyl-CoA carboxylase (ACACA and ACACB)
CC and hormone-sensitive lipase (LIPE) enzymes, respectively
CC (PubMed:2369897, PubMed:9029219). Promotes lipolysis of lipid droplets
CC by mediating phosphorylation of isoform 1 of CHKA (CHKalpha2) (By
CC similarity). Regulates insulin-signaling and glycolysis by
CC phosphorylating IRS1, PFKFB2 and PFKFB3 (PubMed:11069105,
CC PubMed:11598104, PubMed:12065600). Involved in insulin receptor/INSR
CC internalization (By similarity). AMPK stimulates glucose uptake in
CC muscle by increasing the translocation of the glucose transporter
CC SLC2A4/GLUT4 to the plasma membrane, possibly by mediating
CC phosphorylation of TBC1D4/AS160 (By similarity). Regulates
CC transcription and chromatin structure by phosphorylating transcription
CC regulators involved in energy metabolism such as CRTC2/TORC2, FOXO3,
CC histone H2B, HDAC5, MEF2C, MLXIPL/ChREBP, EP300, HNF4A, p53/TP53,
CC SREBF1, SREBF2 and PPARGC1A (PubMed:11724780, PubMed:12740371). Acts as
CC a key regulator of glucose homeostasis in liver by phosphorylating
CC CRTC2/TORC2, leading to CRTC2/TORC2 sequestration in the cytoplasm (By
CC similarity). In response to stress, phosphorylates 'Ser-36' of histone
CC H2B (H2BS36ph), leading to promote transcription (By similarity). Acts
CC as a key regulator of cell growth and proliferation by phosphorylating
CC TSC2, RPTOR and ATG1/ULK1: in response to nutrient limitation,
CC negatively regulates the mTORC1 complex by phosphorylating RPTOR
CC component of the mTORC1 complex and by phosphorylating and activating
CC TSC2 (By similarity). In response to nutrient limitation, promotes
CC autophagy by phosphorylating and activating ATG1/ULK1 (By similarity).
CC In that process also activates WDR45/WIPI4 (By similarity).
CC Phosphorylates CASP6, thereby preventing its autoprocessing and
CC subsequent activation (By similarity). AMPK also acts as a regulator of
CC circadian rhythm by mediating phosphorylation of CRY1, leading to
CC destabilize it (By similarity). May regulate the Wnt signaling pathway
CC by phosphorylating CTNNB1, leading to stabilize it (By similarity).
CC Also acts as a regulator of cellular polarity by remodeling the actin
CC cytoskeleton; probably by indirectly activating myosin (By similarity).
CC Also phosphorylates CFTR, EEF2K, KLC1, NOS3 and SLC12A1
CC (PubMed:10025949, PubMed:14709557, PubMed:17341212). Plays an important
CC role in the differential regulation of pro-autophagy (composed of
CC PIK3C3, BECN1, PIK3R4 and UVRAG or ATG14) and non-autophagy (composed
CC of PIK3C3, BECN1 and PIK3R4) complexes, in response to glucose
CC starvation (By similarity). Can inhibit the non-autophagy complex by
CC phosphorylating PIK3C3 and can activate the pro-autophagy complex by
CC phosphorylating BECN1 (By similarity). {ECO:0000250|UniProtKB:P54646,

CC -!- ACTIVITY REGULATION: Activated by phosphorylation on Thr-172. Binding
CC of AMP to non-catalytic gamma subunit (PRKAG1, PRKAG2 or PRKAG3)
CC results in allosteric activation, inducing phosphorylation on Thr-172.
CC AMP-binding to gamma subunit also sustains activity by preventing
CC dephosphorylation of Thr-172. ADP also stimulates Thr-172
CC phosphorylation, without stimulating already phosphorylated AMPK. ATP
CC promotes dephosphorylation of Thr-172, rendering the enzyme inactive.
CC Under physiological conditions AMPK mainly exists in its inactive form
CC in complex with ATP, which is much more abundant than AMP. Selectively
CC inhibited by compound C (6-[4-(2-Piperidin-1-yl-ethoxy)-phenyl)]-3-
CC pyridin-4-yl-pyyrazolo[1,5-a] pyrimidine. Activated by resveratrol, a
CC natural polyphenol present in red wine, and S17834, a synthetic
CC polyphenol. Salicylate/aspirin directly activates kinase activity,
CC primarily by inhibiting Thr-172 dephosphorylation (By similarity).
CC {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.
CC Associates with internalized INSR complexes on Golgi/endosomal
CC membranes; PRKAA2/AMPK2 together with ATIC and HACD3/PTPLAD1 is
CC proposed to be part of a signaling network regulating INSR
CC autophosphorylation and endocytosis (PubMed:25687571). Interacts with
CC DUSP29 (By similarity). {ECO:0000250|UniProtKB:Q8BRK8,

CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q8BRK8}. Nucleus

CC -!- TISSUE SPECIFICITY: Skeletal muscle, lower levels in liver, heart and
CC kidney.
CC -!- INDUCTION: By AMP.
CC -!- DOMAIN: The AIS (autoinhibitory sequence) region shows some sequence
CC similarity with the ubiquitin-associated domains and represses kinase
CC activity. {ECO:0000250|UniProtKB:Q13131}.

CC -!- PTM: Phosphorylated at Thr-172 by STK11/LKB1 in complex with STE20-
CC related adapter-alpha (STRADA) pseudo kinase and CAB39. Also
CC phosphorylated at Thr-172 by CAMKK2; triggered by a rise in
CC intracellular calcium ions, without detectable changes in the AMP/ATP
CC ratio. CAMKK1 can also phosphorylate Thr-172, but at much lower level.
CC Dephosphorylated by protein phosphatase 2A and 2C (PP2A and PP2C).
CC Phosphorylated by ULK1; leading to negatively regulate AMPK activity
CC and suggesting the existence of a regulatory feedback loop between ULK1
CC and AMPK. Dephosphorylated by PPM1A and PPM1B at Thr-172 (mediated by
CC STK11/LKB1) (By similarity). {ECO:0000250}.
CC -!- MISCELLANEOUS: [Isoform Short]: Lacks the sequence parts essential for
CC kinase activity and is therefore inactive. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. CAMK Ser/Thr
CC protein kinase family. SNF1 subfamily. {ECO:0000305}.
