<Li> Key: XNOPRXBHLZRZKH - DSZYJQQASA - N </Li> <Tr> <Th_colspan="2"> (verify) </Th> </Tr> <P> Oxytocin (Oxt; / ˌɒksɪˈtoʊsɪn /, / ˌɒksi - /) is a peptide hormone and neuropeptide . Oxytocin is normally produced by the paraventricular nucleus of the hypothalamus and released by the posterior pituitary . It plays a role in social bonding, sexual reproduction in both sexes, and during and after childbirth . Oxytocin is released into the bloodstream as a hormone in response to stretching of the cervix and uterus during labor and with stimulation of the nipples from breastfeeding . This helps with birth, bonding with the baby, and milk production . Oxytocin was discovered by Henry Dale in 1906 . Its molecular structure was discovered in 1952 . Oxytocin is also used as a medication to facilitate childbirth . </P> <Table> <Tr> <Th_colspan="4"> OXT </Th> </Tr> <Tr> <Td_colspan="4"> </Td> </Tr> <Tr> <Th_colspan="4"> Identifiers </Th> </Tr> <Tr> <Th> Aliases </Th> <Td_colspan="3"> OXT, OT, OT - NPI, OXT - NPI, oxytocin / neurophysin I prepropeptide </Td> </Tr> <Tr> <Th> External IDs </Th> <Td_colspan="3"> OMIM: 167050 MGI: 97453 HomoloGene: 55494 GeneCards: OXT </Td> </Tr> <Tr> <Td_colspan="4"> <Table> <Tr> <Th_colspan="4"> (hide) Gene location (Human) </Th> </Tr> <Tr> <Td_colspan="4"> </Td> </Tr> <Tr> <Th> Chr . </Th> <Td_colspan="3"> Chromosome 20 (human) </Td> </Tr> <Tr> <Td_colspan="4"> </Td> </Tr> <Tr> <Th> Band </Th> <Td> n / a </Td> <Th> Start </Th> <Td> 3,071,620 bp </Td> </Tr> <Tr> <Th> End </Th> <Td> 3,072,517 bp </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td_colspan="4"> <Table> <Tr> <Th_colspan="4"> (show) Gene location (Mouse) </Th> </Tr> <Tr> <Td_colspan="4"> </Td> </Tr> <Tr> <Th> Chr . </Th> <Td_colspan="3"> Chromosome 2 (mouse) </Td> </Tr> <Tr> <Td_colspan="4"> </Td> </Tr> <Tr> <Th> Band </Th> <Td> n / a </Td> <Th> Start </Th> <Td> 130,576,173 bp </Td> </Tr> <Tr> <Th> End </Th> <Td> 130,577,054 bp </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td_colspan="4"> <Table> <Tr> <Th_colspan="4"> (show) Gene ontology </Th> </Tr> <Tr> <Th> Molecular function </Th> <Td> oxytocin receptor binding hormone activity neurohypophyseal hormone activity neuropeptide hormone activity </Td> </Tr> <Tr> <Th> Cellular component </Th> <Td> terminal bouton extracellular region cytoplasm secretory granule extracellular space </Td> </Tr> <Tr> <Th> Biological process </Th> <Td> response to amphetamine regulation of digestive system process sperm ejaculation positive regulation of hindgut contraction female pregnancy positive regulation of penile erection response to steroid hormone signal transduction response to activity regulation of heart rate response to sucrose positive regulation of ossification positive regulation of synapse assembly drinking behavior hyperosmotic salinity response male mating behavior positive regulation of cytosolic calcium ion concentration response to estradiol regulation of sensory perception of pain response to cAMP response to cocaine response to progesterone positive regulation of blood pressure heart development negative regulation of urine volume response to organic cyclic compound negative regulation of gastric acid secretion positive regulation of prostaglandin secretion response to peptide hormone maternal behavior negative regulation of blood pressure memory positive regulation of norepinephrine secretion social behavior response to glucocorticoid grooming behavior response to prostaglandin E eating behavior response to ether positive regulation of female receptivity sleep maternal aggressive behavior positive regulation of synaptic transmission response to electrical stimulus positive regulation of uterine smooth muscle contraction response to food response to retinoic acid positive regulation of renal sodium excretion </Td> </Tr> <Tr> <Td_colspan="4"> Sources: Amigo / QuickGO </Td> </Tr> </Table> </Td> </Tr> <Tr> <Th_colspan="4"> Orthologs </Th> </Tr> <Tr> <Th> Species </Th> <Td> Human </Td> <Td> Mouse </Td> </Tr> <Tr> <Th> Entrez </Th> <Td> <Table> <Tr> <Th_colspan="1"> </Th> </Tr> <Tr> <Td_colspan="1"> <P> 5020 </P> </Td> </Tr> </Table> </Td> <Td> <Table> <Tr> <Th_colspan="1"> </Th> </Tr> <Tr> <Td_colspan="1"> <P> 18429 </P> </Td> </Tr> </Table> </Td> </Tr> <Tr> <Th> Ensembl </Th> <Td> <Table> <Tr> <Th_colspan="1"> </Th> </Tr> <Tr> <Td_colspan="1"> <P> ENSG00000101405 </P> </Td> </Tr> </Table> </Td> <Td> <Table> <Tr> <Th_colspan="1"> </Th> </Tr> <Tr> <Td_colspan="1"> <P> ENSMUSG00000027301 </P> </Td> </Tr> </Table> </Td> </Tr> <Tr> <Th> UniProt </Th> <Td> <Table> <Tr> <Th_colspan="1"> </Th> </Tr> <Tr> <Td_colspan="1"> <P> P01178 </P> </Td> </Tr> </Table> </Td> <Td> <Table> <Tr> <Th_colspan="1"> </Th> </Tr> <Tr> <Td_colspan="1"> <P> P35454 </P> </Td> </Tr> </Table> </Td> </Tr> <Tr> <Th> RefSeq (mRNA) </Th> <Td> <Table> <Tr> <Th_colspan="1"> </Th> </Tr> <Tr> <Td_colspan="1"> <P> NM_000915 </P> </Td> </Tr> </Table> </Td> <Td> <Table> <Tr> <Th_colspan="1"> </Th> </Tr> <Tr> <Td_colspan="1"> <P> NM_011025 </P> </Td> </Tr> </Table> </Td> </Tr> <Tr> <Th> RefSeq (protein) </Th> <Td> <Table> <Tr> <Th_colspan="1"> </Th> </Tr> <Tr> <Td_colspan="1"> <P> NP_000906 </P> </Td> </Tr> </Table> </Td> <Td> <Table> <Tr> <Th_colspan="1"> </Th> </Tr> <Tr> <Td_colspan="1"> <P> NP_035155 </P> </Td> </Tr> </Table> </Td> </Tr> <Tr> <Th> Location (UCSC) </Th> <Td> Chr 20: 3.07--3.07 Mb </Td> <Td> Chr 20: 130.58--130.58 Mb </Td> </Tr> <Tr> <Th> PubMed search </Th> <Td> </Td> <Td> </Td> </Tr> <Tr> <Td_colspan="4"> Wikidata </Td> </Tr> <Tr> <Td_colspan="4"> <Table> <Tr> <Td_colspan="2"> View / Edit Human </Td> <Td_colspan="2"> View / Edit Mouse </Td> </Tr> </Table> </Td> </Tr> </Table>
