Descriptions

AMP-activated protein kinase (AMPK) acts as an energy sensor, being activated by metabolic stresses and regulating cellular metabolism. AMPK is a heterotrimer consisting of a catalytic alpha subunit and two regulatory subunits, beta and gamma. AMPK alpha subunit contains an autoinhibitory domain that inhibits the N-terminal kinase domain. Autoinhibitory region of AMPK alpha are not only responsible for kinase autoinhibition, but may also be responsible for full-length kinase degradation.

2 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
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.

6 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
histone deacetylase inhibitor activity Binds to and stops, prevents or reduces the activity of histone deacetylase, which catalyzes of the removal of acetyl groups from histones, proteins complexed to DNA in chromatin and chromosomes.
metal ion binding Binding to a metal ion.
protein kinase activity Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction
protein serine kinase activity Catalysis of the reactions
protein serine/threonine kinase activity Catalysis of the reactions

12 GO annotations of biological process

Name Definition
dauer entry Entry into the facultative diapause of the dauer (enduring) larval stage of nematode development.
dauer larval development The process whose specific outcome is the progression of the dauer larva over time, through the facultative diapause of the dauer (enduring) larval stage, with specialized traits adapted for dispersal and long-term survival, with elevated stress resistance and without feeding.
intracellular signal transduction The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell.
negative regulation of fatty acid biosynthetic process Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of fatty acids.
phosphorylation The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.
positive regulation of gene expression Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product (protein or RNA).
positive regulation of growth rate Any process that increases the rate of growth of all or part of an organism.
positive regulation of multicellular organism growth Any process that activates or increases the frequency, rate or extent of growth of an organism to reach its usual body size.
regulation of multicellular organism growth Any process that modulates the frequency, rate or extent of growth of the body of an organism so that it reaches its usual body size.
reproduction The production of new individuals that contain some portion of genetic material inherited from one or more parent organisms.
response to heat Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a heat stimulus, a temperature stimulus above the optimal temperature for that organism.
transforming growth factor beta receptor signaling pathway The series of molecular signals initiated by an extracellular ligand binding to a transforming growth factor beta receptor on the surface of a target cell, and ending with the regulation of a downstream cellular process, e.g. transcription.
