G-protein spregnuti estrogenski receptor 1 (GPER), takođe poznat kao membranski estrogenski receptor (mER) ili G-protein spregnuti receptor 30 (GPR30), je G protein-spregnuti receptor koji je kod čoveka kodiran GPER genom.[1] GPR30 je integralni membranski protein sa visokim afinitetom za estrogen.[2][3][4][5]

Funkcija uredi

Ovaj protein je član familije rodopsinu-sličnih G protein-spregnutih receptora. GPR30 vezuje estrogen, što dovodi do mobilizacije intracelularnog kalcijuma i sinteze fosfatidilinozitol (3,4,5)-trisfosfata u nukleusu. Ovaj protein učestvuje u brzim negenomskim signalnim eventima. Alternativne transkripcione splajsne varijante koje kodiraju isti protein su bile karakterisane.[6] The distribution of GPR30 is well established in the rodent, with high expression observed in the hypothalamus, pituitary gland, adrenal medulla, kidney medulla and developing follicles of the ovary.[7]

Klinički značaj uredi

GPR30 ima važnu ulogu u razvoju tamoksifen otpornosti kod ćelija raka dojke.[8]
