Beta polipeptid luteinizirajućeg hormona (lutropinska podjedinica beta) je protein koji je kod ljudi kodiran LHB genom.[1][2]
Gen
[уреди | уреди извор]Geni beta lanaca horionskih gonadotropina i luteinizirajućeg hormona su dodirni na hromozomu 19q13.3.[2] Kod konja je ova podjedinica kodirana istim genom kao beta podjedinica horionskog gonadatropina.[3]
Funkcija
[уреди | уреди извор]Ovaj gen je član glikoproteinske familije hormonskih beta lanaca. On kodira beta podjedinicu luteinizirajućeg hormona (LH). Glikoproteinski hormoni su heterodimeri koji se sastoje od zajedničke alfa podjedinice i jedinstvene beta podjedinice (ovog proteina) koja im daje biološku specifičnost. LH je izražen u hipofizi. On promoviše spermatogenezu i ovulaciju putem stimulacije testisa i jajnika da sintetišu steroide.[2]
Klinički značaj
[уреди | уреди извор]Mutacije ovog gena su vezane za hipogonadizam koji je karakterisan neplodnošću i pseudohermafroditizmom.[2]
