Schematic diagram of the gonadotropin subunits. These include:
α subunit; LHβ, luteinizing hormone β subunit (the
cross-hatched area of region 115-121 denotes the hydrophobic
heptapeptide); LHβΔT, carboxyl-terminal mutant of LHβ subunit
truncated at amino acid 114; FSHβ, follicle-stimulating hormone β
subunit; FSHβ-L, the cross-hatched area of region 112-118
denotes the hydrophobic heptapeptide of LHβ. N, Asn-linked
oligosaccharides.
