UniProtKB description:  Serine/threonine protein kinase essential for release from glucose repression (PubMed:1944227, PubMed:25869125, PubMed:3049551, PubMed:3526554, PubMed:6366512, PubMed:8289797, PubMed:8628258). Catalytic subunit of the AMP-activated protein kinase complex also known as the SNF1 kinase complex (Snf1c), a central regulator of cellular energy homeostasis, which, in response to a fall in intracellular ATP levels, activates energy-producing pathways and inhibits energy-consuming processes (PubMed:26667037, PubMed:8289797). The complex phosphorylates histone H3 to form H3S10ph, which promotes H3K14ac formation, leading to transcriptional activation through TBP recruitment to the promoters (PubMed:15719021). The complex also negatively regulates the HOG1 MAPK pathway in ER stress response including unfolded protein response (UPR) (PubMed:25730376, PubMed:26394309). Under nutrient/energy depletion, the complex phosphorylates and activates PAS kinase PSK1 which in turn activates PBS1, leading to the inhibition of the TORC1 signaling pathway (PubMed:25428989). SNF1 also interacts and phosphorylates adenylate cyclase CYR1 and negatively regulates the protein kinase A signaling pathway (PubMed:26309257). Also phosphorylates and regulates the transcriptional activator CAT8 (PubMed:15121831).
