edit

LHCGR, luteinizirajući hormon/horiogonadotropinski receptor, lutropin/horiogonadotropinski receptor (LCGR) ili receptor luteinizirajućeg hormona (LHR), je transmembranski receptor nađen u jajnicima, testisima i ekstragonodalnim organima kao što je materica. Ovaj receptor interaguje sa luteinizirajućim hormonom (LH) i horionskim gonadotropinima (kao što je hCG kod čoveka). On je član familije G protein-spregnutih receptora. Njegova aktivacija je neophodna za funkcionisanje hormona tokom reprodukcije.

LHCGR gen uredi

LHCGR gen je nađen na hromozomu 2 p21 kod ljudi, blizo gena FSH receptora. On se sastoji od 70 kbp (versus 54 kpb za FSHR).^[1] Gen je sličan genima FSH i TSH receptora.

Struktura receptora uredi

LHCGR se sastoji od 674 aminokiselina i ima molekulsku masu od oko 85–95 kDa u zavisnosti od stepena glikozilacije.^[2]

LHCGR abnormalnosti uredi

Mutacije koje dovode do gubitka funkcije ovog receptora mogu da dovedu do neplodnosti kod žena. Opsežna inaktivacija može da uzrokuje pseudohermafroditizam muškaraca, zbog odsustva responsa fetalnih Leidigovih ćelija i stoga indukuje maskulinizacije.^[3] Inaktivacija manje jačine može da dovede do hipospadije ili do razvoja mikropenisa.^[2]

Istorija uredi

Alfred G. Gilman i Martin Rodbel su nagrađeni Nobelovom nagradom za fiziologiju ili medicinu 1994. za otkriće G proteinskog sistema.

Interakcije uredi

Za luteinizirajući hormon/horiogonadotropinski receptor da interaguje sa GIPC1.^[4]
