The N-terminal domain of the human androgen receptor is encoded by one, large exon.
Using specific cDNA hybridization probes, the first coding exon of the human androgen receptor gene was isolated from a genomic library. The exon contained an open reading frame of 1586 bp, encoding an androgen receptor amino-terminal region of 529 amino acids. The deduced amino acid sequence was characterized by the presence of several poly-amino acid stretches of which the long poly-glycine stretch (16 residues) and the poly-glutamine stretch (20 residues) were most prominent. Androgen receptor cDNAs from different sources contained information for poly-glycine stretches of variable size (23 and 27 residues, respectively). The androgen receptor amino-terminal domain was found to be hydrophilic and have a net negative charge. Combined with the previously described, partially overlapping cDNA clone 7A2M27 (Trapman et al. (1988) Biochem. Biophys. Res. Commun. 153, 241-248), the complete human androgen receptor was deduced to have a size of 910 amino acids.
