LHCGR,luteinizirajući hormon/horiogonadotropinski receptor,lutropin/horiogonadotropinski receptor (LCGR) ilireceptor luteinizirajućeg hormona (LHR), jetransmembranski receptor nađen ujajnicima,testisima i ekstragonodalnim organima kao što jematerica. Ovaj receptor interaguje saluteinizirajućim hormonom (LH) i horionskim gonadotropinima (kao što jehCG kod čoveka). On je član familijeG protein-spregnutih receptora. Njegova aktivacija je neophodna za funkcionisanje hormona tokom reprodukcije.

LHCGR gen

[uredi |uredi kod]

LHCGRgen je nađen nahromozomu 2 p21 kod ljudi, blizo genaFSH receptora. On se sastoji od 70 kbp (versus 54 kpb zaFSHR).^[1] Gen je sličan genima FSH i TSH receptora.

Struktura receptora

[uredi |uredi kod]

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

LHCGR abnormalnosti

[uredi |uredi kod]

Mutacije koje dovode do gubitka funkcije ovog receptora mogu da dovedu doneplodnosti kod žena. Opsežna inaktivacija može da uzrokujepseudohermafroditizam muškaraca, zbog odsustva responsa fetalnih Leidigovih ćelija i stoga indukuje maskulinizacije.^[3] Inaktivacija manje jačine može da dovede dohipospadije ili do razvojamikropenisa.^[2]

Historija

Alfred G. Gilman iMartin Rodbel su nagrađeniNobelovom nagradom za fiziologiju ili medicinu 1994. za otkriće G proteinskog sistema.
