Each hormone is composed of two dissimilar, non-covalently linked glycosylated subunits, α and β. The mammalian genome contains a single gene encoding the α-subunit which is common to each of the glycoprotein hormones (Fiddes & Goodman, 1981). In contrast, the β-subunits of each hormone are encoded by different genes and confer biological and immunological specificity upon the intact dimer.The gene encoding the β-subunit of TSH has been assigned to chromosome 1 in man (Fukushige, Murotsu & Matsubara, 1986) and chromosome 3 in the mouse (Kourides, Barker, Gurr et al. 1984). The α-gene, unlike the β-gene, has been assigned in the mouse to chromosome 4 (Kourides et al.
