Descriptions
SNF1, a member of the SNF1/AMPK family, is required for the adaptation of yeast cells to glucose limitation and for growth on carbon sources that are less preferred than glucose. SNF1 regulates transcription of a large set of genes, modifies the activity of metabolic enzymes, and controls various nutrient-responsive cellular developmental processes. In yeast, the SNF1 kinase is complexed with the SNF4 protein, which is required for SNF1 kinase activity. In glucose-grown cells, the SNF1 kinase complex exists predominantly in an inactive autoinhibited conformation in which the catalytic domain of SNF1 binds to the regulatory domain of the protein. When glucose is limiting, the catalytic domain is released and the activating subunit SNF4 binds to the regulatory domain, which leads to an active, open conformation of the complex. Activation requires phosphorylation and an essential, conserved threonine in the activation loop of SNF1, which is phosphorylated during the activation of other kinases.

---|---|
cellular bud neck septin ring | A ring-shaped structure that forms at the site of cytokinesis in the bud neck of a budding cell; composed of members of the conserved family of filament forming proteins called septins as well as septin-associated proteins. In S. cerevisiae, this structure forms at the time of bud emergence and the septins show a high rate of exchange. |
cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
mitochondrion | A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration. |
nuclear envelope lumen | The region between the two lipid bilayers of the nuclear envelope; 20-40 nm wide. |
nuclear membrane | Either of the lipid bilayers that surround the nucleus and form the nuclear envelope; excludes the intermembrane space. |
nucleotide-activated protein kinase complex | A protein complex that possesses nucleotide-dependent protein kinase activity. The nucleotide can be AMP (in S. pombe and human) or ADP (in S. cerevisiae). |
nucleus | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
vacuolar membrane | The lipid bilayer surrounding the vacuole and separating its contents from the cytoplasm of the cell. |
8 GO annotations of molecular function
Name | Definition |

AMP-activated protein kinase activity | Catalysis of the reaction: ATP + a protein = ADP + a phosphoprotein. This reaction requires the presence of AMP. |
ATP binding | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
guanyl-nucleotide exchange factor activity | Stimulates the exchange of GDP to GTP on a signaling GTPase, changing its conformation to its active form. Guanine nucleotide exchange factors (GEFs) act by stimulating the release of guanosine diphosphate (GDP) to allow binding of guanosine triphosphate (GTP), which is more abundant in the cell under normal cellular physiological conditions. |
identical protein binding | Binding to an identical protein or proteins. |
protein kinase activity | Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction: a protein + ATP = a phosphoprotein + ADP. |
protein serine kinase activity | Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate. |
protein serine/threonine kinase activity | Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate. |
protein serine/threonine/tyrosine kinase activity | Catalysis of the reactions: ATP + a protein serine = ADP + protein serine phosphate; ATP + a protein threonine = ADP + protein threonine phosphate; and ATP + a protein tyrosine = ADP + protein tyrosine phosphate. |
