NCIt definition : A heterodimeric glycoprotein hormone secreted by the gonadotropic cells of the anterior
pituitary gland. This hormone is involved in stimulation of testosterone production
by Leydig cells in males and triggering ovulation and corpus luteum development in
females.;
NCIt note : Luteinizing hormone is comprised of an alpha chain, glycoprotein hormones alpha chain
(CGA), which is the common alpha chain shared with LH, TSH, and hCG, and a unique
beta chain, lutropin subunit beta (LHB), which confers specific binding to lutropin-choriogonadotropic
hormone receptor (LHCGR).;
