Target Data

Function Catalytic subunit of AMP-activated protein kinase (AMPK), an energy sensor protein kinase that plays a key role in regulating cellular energy metabolism. In response to reduction of intracellular ATP levels, AMPK activates energy-producing pathways and inhibits energy-consuming processes
Gene References into Functions
  1. PRKAA2 Polymorphisms in rs10789038 and rs2796498 are associated with the susceptibility to type 2 diabetes mellitus and diabetic nephropathy. PMID: 28322508

  3. PGC-1alpha protein was higher after HIHVT than after SIT (p < 0.05). Moreover, the AMPKpTHR172/AMPK ratio increased at post after SIT (p < 0.05), whereas this effect was delayed after HIHVT as it increased after 3 h PMID: 28973039
  4. TNF-alpha treatment of colonic rho(0) cells augmented IL-8 expression by 9-fold (P < 0.01) via NF-kappaB compared to TNF-alpha-treated control. Moreover, reduced mitochondrial function facilitated TNF-alpha-mediated NF-kappaB luciferase promoter activity as a result of lowered inhibitory IkappaBalpha (nuclear factor of kappa light polypeptide gene enhancer in B-cell inhibitor, alpha), leading to elevated NF-kappaB. ... PMID: 28183804
  5. Results highlight the contribution of AMPKalpha2 as a mechanism for controlling bladder cancer growth by regulating proliferation through mTOR suppression and induction of p27 protein levels, thus indicating how AMPKalpha2 loss may contribute to tumorigenesis. PMID: 27638620
  6. AMPK phosphorylation of cortactin followed by SIRT1 deacetylation modulates the interaction of cortactin and cortical-actin in response to shear stress. Functionally, this AMPK/SIRT1 coregulated cortactin-F-actin dynamics is required for endothelial nitric oxide synthase subcellular translocation/activation and is atheroprotective. PMID: 27758765
