NCIt synonyms : Nuclear Receptor Subfamily 3 Group C Member 4; Dihydrotestosterone Receptor; AR; NR3C4; DHTR;
NCIt definition : Androgen receptor (919 aa, 99 kDa) is encoded by the human AR gene. This protein
plays a role in the modulation of steroid-dependent gene transcription.;
NCIt note : AR has 3 domains: N-terminal modulating (exon 1), DNA-binding (two C4 Zinc fingers,
exons 2-3), and C-terminal hormone-binding (5 remaining exons). Polymorphic N-terminal
poly-Gln tracts bind RAN, enhancing transactivation; decreased with increased poly-Gln
length. An 87-kD (AR-A) isoform lacks a normal N-terminus, seen in the 110 kD (AR-B)
form; A and B may differ in function. Ligand bound receptor translocates to the nucleus,
homodimerizes, binds DNA, and stimulates transcription.;
