Involved In
This protein is involved in 18 target(s):
| Target | Category | Definition |
|---|---|---|
| response to hypoxia | biological process | 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 stimulus indicating lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level. [GOC:hjd] |
| response to ischemia | biological process | Any process that results in a change in state or activity of an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a inadequate blood supply. [GOC:hjd] |
| detection of hypoxic conditions in blood by carotid body chemoreceptor signaling | biological process | The process in which information about a lack of oxygen are received and are converted to a molecular signal by chemoreceptors in the carotid bodies. [GOC:mtg_cardio] |
| neuromuscular synaptic transmission | biological process | The process of synaptic transmission from a neuron to a muscle, across a synapse. [GOC:dos, GOC:jl, MeSH:D009435] |
| neuromuscular junction development | biological process | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a neuromuscular junction. [GOC:mtg_OBO2OWL_2013] |
| sensory perception of sound | biological process | The series of events required for an organism to receive an auditory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Sonic stimuli are detected in the form of vibrations and are processed to form a sound. [GOC:ai] |
| response to carbohydrate | biological process | 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 carbohydrate stimulus. [GOC:jl] |
| positive regulation of calcium ion transport into cytosol | biological process | Any process that increases the rate of the directed movement of calcium ions into the cytosol of a cell. The cytosol is that part of the cytoplasm that does not contain membranous or particulate subcellular components. [GOC:dph, GOC:tb] |
| urinary bladder smooth muscle contraction | biological process | A process in which force is generated within smooth muscle tissue, resulting in a change in muscle geometry. This process occurs in the urinary bladder. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. The urinary bladder is a musculomembranous sac along the urinary tract. [GOC:mr, GOC:mtg_muscle, PMID:11768524, PMID:18276178, PMID:538956] |
| peristalsis | biological process | A wavelike sequence of involuntary muscular contraction and relaxation that passes along a tubelike structure, such as the intestine, impelling the contents onwards. [ISBN:0198506732] |
| response to ATP | biological process | 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 an ATP (adenosine 5'-triphosphate) stimulus. [GOC:sl] |
| purinergic nucleotide receptor signaling pathway | biological process | The series of molecular signals initiated by an extracellular purine nucleotide binding to its receptor, and ending with the regulation of a downstream cellular process, e.g. transcription. [GOC:BHF, PMID:9755289] |
| behavioral response to pain | biological process | Any process that results in a change in the behavior of an organism as a result of a pain stimulus. Pain stimuli cause activation of nociceptors, peripheral receptors for pain, include receptors which are sensitive to painful mechanical stimuli, extreme heat or cold, and chemical stimuli. [GOC:jid] |
| skeletal muscle fiber development | biological process | The process whose specific outcome is the progression of the skeletal muscle fiber over time, from its formation to the mature structure. Muscle fibers are formed by the maturation of myotubes. They can be classed as slow, intermediate/fast or fast. [GOC:dph, GOC:ef, GOC:jid, GOC:lm, GOC:mtg_muscle] |
| positive regulation of calcium-mediated signaling | biological process | Any process that activates or increases the frequency, rate or extent of calcium-mediated signaling. [GOC:ai] |
| sensory perception of taste | biological process | The series of events required for an organism to receive a gustatory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Gustation involves the direct detection of chemical composition, usually through contact with chemoreceptor cells. This is a neurological process. [GOC:ai] |
| excitatory postsynaptic potential | biological process | A process that leads to a temporary increase in postsynaptic potential due to the flow of positively charged ions into the postsynaptic cell. The flow of ions that causes an EPSP is an excitatory postsynaptic current (EPSC) and makes it easier for the neuron to fire an action potential. [GOC:dph, GOC:ef] |
| calcium ion transmembrane transport | biological process | A process in which a calcium ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore. [GOC:mah] |
