黃體生成素β亞基（英語：Luteinizing hormone subunit beta 或 lutropin subunit beta ）是一種由人類基因LHB 編碼的蛋白質[1][2]。

目錄

基因

該基因位於19號染色體q13.3，編碼黃體生成素的β亞基[2] In equines, this subunit is encoded by the same gene as the beta subunit of chorionic gonadatropin, subunits which are identical.[3]。

功能

This gene is a member of the glycoprotein hormone beta chain family and encodes the beta subunit of luteinizing hormone (LH). Glycoprotein hormones are heterodimers consisting of a common alpha subunit and a unique beta subunit (this protein) which confers biological specificity. LH is expressed in the pituitary gland and promotes spermatogenesis and ovulation by stimulating the testes and ovaries to synthesize steroids.[2]

臨床意義

Mutations in this gene are associated with hypogonadism which is characterized by infertility and pseudohermaphroditism.[2]
