Figure 7.Human androgen receptor gene was mapped to the long arm of the X-chromosome. The human androgen receptor protein (919 amino acid residues) is encoded by 8 exons. Analogous to other nuclear receptors the protein consists of several distinct functional domains: the NH2-terminal domain containing two polymorphic stretches, the DNA-binding domain, the hinge region and the ligand binding domain.
