metabolism
-
is a key regulator of cellular and whole-body energy homeostasis that co-ordinates metabolic pathways in order to balance nutrient supply with energy demand
metabolism
-
active AMPK promotes the functional recovery of beta-cell oxidative metabolism and abrogates the induction of pathways that mediate cell death such as caspase-3 activation following exposure to nitric oxide
metabolism
-
is a metabolic energy regulator that can switch acid secretion off as cellular ATP levels fall. Secretagogue-induced acid secretion can be significantly reduced with AMPK activation and restored with its deactivation
physiological function
-
role of AMPK is that it monitors cellular energy status by sensing the relative cellular concentrations of AMP and ATP. The beta-subunits of AMPK contain a glycogen-binding domain, which is a regulatory domain that allows AMPK to act as a sensor of the status of cellular reserves of energy in the form of glycogen. The pool of AMPK that is bound to the glycogen particle is in an active state when glycogen particles are fully synthesized, causing phosphorylation of glycogen synthase at site 2 and providing a feedback inhibition of further extension of the outer chains of glycogen
physiological function
-
AMPK is responsible for phosphorylation of site 2 in vivo. Both basal and 5-aminoimidazole-4-carboxamide riboside (AICAR)-stimulated site 2 phosphorylation is greatly reduced in muscles of AMPK-alpha2 knockout mice
physiological function
-
AMPK activation dramatically decreases de novo fatty acid synthesis and inactivates ACCalpha. AMPK activation modifies lipogenic gene expression including fatty acid synthase, glycerol-3-phosphate acyltransferase, and fatty acid binding protein-3. AMPK is able to inhibit fatty acid synthesis, an energy consuming process, in response to decreases in energy supply
physiological function
-
activation of AMPK may prevent neuronal cell death and play a role as a survival factor in Parkinson's disease. Overexpression of AMPK increases cell viability after exposure to 1-methyl-4-pyridinium in SH-SY5Y cells
physiological function
-
activation of AMPK may prevent neuronal cell death and play a role as a survival factor in Parkinson's disease
physiological function
-
AMPK is required for proper cell division and faithful chromosomal segregation during mitosis. Active form of the alpha-catalytic AMPK subunit (P-AMPKalpha-Thr172), but not its total form (AMPKalpha), transiently associates with several mitotic structures including centrosomes, spindle poles, the central spindle midzone and the midbody throughout all of the mitotic stages and cytokinesis in human cancer-derived epithelial cells
physiological function
-
AMPK may play an important role in protecting endothelial cells against adverse effects of sustained hyperglycaemia, such as alterations in fatty acid metabolism, impaired Akt activation by insulin, increased caspase 3 activity and apoptosis. It may modulate endothelial cell energy supply. The AMPK-acetyl CoA carboxylase-malonyl CoA-carnitine palmitoyl-transferase 1 mechanism for regulating long-chain fatty acid oxidation, similar to that of muscle, operates in the endothelial cell and is regulated by AMPK under physiological conditions. One way to deal with endothelial lipotoxicity is to promote free fatty acid oxidation and ameliorate lipid accumulation in endothelial cells, which can be achieved by activating endothelial AMPK. AMPK inhibits fatty acid-induced increases in NF-kappaB transactivation in cultured human umbilical vein endothelial cells
physiological function
-
AMPK activation alters the expression of a variety of genes, including phosphoenolpyruvate carboxykinase in hepatocytes. Reduced AMPK activation may play an important role in the lipid accumulation and genesis of endothelial dysfunction in obese rats. Endothelial AMPK activity may inhibit glycerol-3-phosphate acyltransferase, required for de novo synthesis of diacylglycerol
physiological function
-
AMPK activation inhibits TNFa-stimulated leukocyte adhesion to aortic endothelial cells and ICAM-1 mediated migration of lymphocytes across primary microvascular endothelial cells
physiological function
-
AMPK activation induces vasodilatation and blood flow regulation in wild-type mice and this effect is abolished in AMPKalpha1 knockout mice. Chronic activation of AMPK in vivo attenuates ROS-mediated c-Jun N-terminal kinase activation and endothelial dysfunction in response to angiotensin II, which is abrogated in mice lacking the endothelial isoform of AMPKalpha1 or peroxisome proliferator gamma coactivator-1alpha, a target of AMPK that controls mitochondrial biogenesis. AMPK-deficient mice demonstrate impairment in postischemic fatty acid oxidation. In the setting of systolic pressure overload, left ventricular hypertrophy ensues and AMPKalpha2 knockout mice exhibit significantly increased overload-induced ventricular hypertrophy and decreased left ventricular ejection fraction. Isolated hearts of AMPK-deleted mice show increased apoptosis and dysfunction after ischemia/reperfusion. Role of AMPK in regulation of apoptosis that is an important mechanism of heart failure

transgenic littermates overexpressing an alpha2AMPK kinase-dead (KD) have reduced skeletal muscle alpha2AMPK activity (50% in gastrocnemius and more than 80% in soleus and extensor digitorum longus) and acetyl-CoA carboxylase-2 Ser228 phosphorylation (90% in gastrocnemius). Obesity in response to high-fat feeding is not associated with impaired AMPK actions, obesity-induced lipid accumulation and insulin resistance are not exacerbated in AMPK KD mice
physiological function
-
critical role of AMPK in the survival of circulating erythrocytes. As compared with erythrocytes from wild-type littermates (ampk+/+), erythrocytes from AMPKalpha1-deficient mice (ampk-/-) are significantly more susceptible to the eryptotic effect of energy depletion. The ampk-/- mice are anemic despite excessive reticulocytosis, and they suffer from severe splenomegaly

AMPK activation inhibits endothelial apoptosis in cultured cells. AMPK activation suppresses the basal and angiotensin II-enhanced superoxide anions in BAEC
physiological function
-
overexpression or ablation of the AMPK gamma3 subunit does not appear to play a critical role in defining mitochondrial content in resting skeletal muscle. Skeletal muscle mitochondrial content is unaltered in AMPK gamma3-/- mice
physiological function
-
AMPK activation during oxidative stress may switch retinal pigment epithelium cells to a self-protected status. Alpha2 but not alpha1 AMPK is involved in retinal pigment epithelium cell phagocytosis and activation of alpha2 AMPK contributes to the inhibition of retinal pigment epithelium cell phagocytosis by oxidative stress
physiological function
-
role for AMPK, in concert with other signals induced by IFNgamma, in mediating reduced epithelial barrier function in a cell model of chronic intestinal inflammation
physiological function
-
AMPK mediates cold-induced resistance to anorexigenic signalling in the hypothalamus. Activation of AMPK can contribute to hyperphagia. Inhibition of AMPK inhibits the hypoglycaemia-induced increase in the counter-regulatory hormones glucagon, corticosterone and catecholamines, causing a severe and prolonged hypoglycaemia
physiological function
-
activation of AMPK alpha is necessary for hypoxia-induced AMPK-PKCzeta binding in alveolar epithelial cells. Overexpression of a dominant-negative AMPK alpha subunit construct prevents hypoxia-induced endocytosis of Na,K-ATPase, hypoxia-induced PKCzeta translocation to the plasma membrane and phosphorylation at Thr410
physiological function
AMP-activated protein kinase (AMPK) is a serine/threonine kinase that functions as a sensor to maintain energy balance at both the cellular and the whole-body levels. The enzyme is activated under circumstances with an increased cellular AMP:ATP ratio, such as metabolic stresses that inhibit ATP production (hypoxia, glucose deprivation, metabolic inhibitors etc.) and those that stimulate ATP consumption (exercise, cell growth and division etc.)
physiological function
AMP-activated protein kinase (AMPK) is metabolic biosensor with anti-inflammatory activities. Gout is commonly associated with excesses in soluble urate and in nutrition, both of which suppress tissue AMPK activity. Gout is driven by macrophage-mediated inflammation transduced partly by NLRP3 inflammasome activation and interleukin-1beta release. AMP-activated protein kinase suppresses urate crystal-induced inflammation and transduces colchicine effects in macrophages. Activated AMPK is anti-inflammatory partly through inhibition of NF-kappaB

AMPK is a metabolic stress-sensing kinase with important functions for red blood cell survival. Identification of putative AMPK targets in hemoglobin-depleted lysates of erythrocytes, including metabolic enzymes, cytoskeletal proteins and enzymes involved in the oxidative stress response, cloning and recombinant expression. AMPK aids the function of red blood cells
physiological function
-
AMPK is a cellular energy sensor that negatively regulates cell growth and proliferation. MAPO1, identified as a component involved in the induction of apoptosis, is stabilized by interaction with AMP-activated protein kinase (AMPK) and folliculin (FLCN). AMPK is activated during the process of O6-methylguanine-induced apoptosis and this activation is dependent on MAPO1 and folliculin. It is likely that the kinase activity of AMPK is involved in the degradation of MAPO1
physiological function
Q13131 AND P54646
AMP-activated protein kinase (AMPK) is a serine/threonine protein kinase that serves as a pleotropic regulator of whole body energy homoeostasis. The enzyme is allosterically regulated, kinetic analysis, overview. Binding of activator AMP to the gamma-subunit allows a small regulatory segment of the alpha-subunit (alpha2 residues 365-371) called the alpha-hook or alpha-RIM2 to directly interact with bound AMP and create an allosteric conformational change at the catalytic active site. As a consequence, the phosphorylated alpha-Thr172/174 can be protected from dephosphorylation by phosphatases and sustain its kinase activity for an extended period

re-feeding after fasting inhibits AMPK activity in multiple hypothalamic regions. Diet-induced obesity mice have suppressed AMPK activity in the paraventricular nucleus of the hypothalamus, AMPK is suppressed to the level in leptin-treated chow-fed mice, and there is no further effect of leptin. In mice, diet-induced obesity alters the effect of leptin on AMPK activity not only in the hypothalamus, but also in the skeletal muscle. Adiponectin-deficient mice show decreased AMPK phosphorylation in the arcuate nucleus. In leptin-over-expressing transgenic mice on a high fat diet, muscle AMPK phosphorylation and acetyl-CoA carboxylase phosphorylation are reduced compared with standard diet leptin-over-expressing transgenic mice and are comparable to high fat diet-non-transgenic mice. Leptin i.c.v., in addition to transgenic hyperleptinaemia, is not able to restore the impaired AMPK signalling because of the induced generalised leptin resistance

dynamical mechanism of autoinhibition of AMP-activated protein kinase, molecular dynamics simulations and modelling, overview. Conformational switch model involving the movement of the kinase domain between an inactive unphosphorylated open state and an active or semi-active phosphorylated closed state, mediated by the autoinhibitory domain (AID). AID inhibits the catalytic function by restraining the kinase domain into an unproductive open conformation, thereby limiting local structural rearrangements, while mutations that disrupt the interactions between the kinase domain and AID allow for both the local structural rearrangement and global interlobe conformational transition. The AID also greatly impacts the structuring and mobility of the activation loop. Binding of AMP to the gamma-subunit changes the interactions between the AID and kinase domain to remove the inhibitory effect of AID to allow the interlobe conformational transition to the closed state. The unphosphorylated KD-AID fragment from Schizosaccharomycespombe (PDB ID 3H4J) is used as a model of the inactive-open state because of its open interlobe conformation, while the phosphorylated kinase domain fragment from Saccharomyces cerevisiae (PDB ID 3DAE) is used as the active-closed state reference, in accord with the experimental structural and mutagenesis analysis. AID inhibits catalytic function by restraining kinase domain to an inactive-open state
