5 GO annotations of cellular component
Name | Definition |
---|---|
axon | The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter. |
cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
neuronal cell body | The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. |
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. |
4 GO annotations of molecular function
Name | Definition |
---|---|
AMP-activated protein kinase activity | Catalysis of the reaction |
ATP binding | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
protein serine kinase activity | Catalysis of the reactions |
protein serine/threonine kinase activity | Catalysis of the reactions |
10 GO annotations of biological process
Name | Definition |
---|---|
cellular response to glucose starvation | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of glucose. |
determination of adult lifespan | The pathways that regulate the duration of the adult phase of the life-cycle of an animal. |
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 protein secretion | Any process that stops, prevents, or reduces the frequency, rate or extent of the controlled release of a protein from a cell. |
negative regulation of TOR signaling | Any process that stops, prevents, or reduces the frequency, rate or extent of TOR signaling. |
nematode pharyngeal pumping | The contraction and relaxation movements of the pharyngeal muscle that mediate feeding in nematodes. |
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 dauer larval development | Any process that increases the rate, frequency, or extent of 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. |
positive regulation of protein secretion | Any process that activates or increases the frequency, rate or extent of the controlled release of a protein from a cell. |
serotonin receptor signaling pathway | The series of molecular signals generated as a consequence of a serotonin receptor binding to one of its physiological ligands. |
