雄激素受體

雄激素受體（英語：androgen receptor，簡稱為AR），亦被稱為NR3C4（核受體亞家族3，C組，成員4）是一類核受體^[6]，當雄性激素睪酮或二氫睪酮^[7]在細胞質中與之結合後會使之激活繼而轉運進核內。雄激素受體與孕酮受體之間的關係很密切，高劑量的黃體製劑可阻斷雄激素受體^[8][9]。

雄激素受體的正常功能。如果細胞中存在5α-還原酶，睪酮（T）進入細胞後就會被轉化為二氫睪酮（DHT）。雄激素受體（AR）一旦與甾體結合後就會發生構象改變並釋放一些熱休克蛋白（hsps）。在甾體結合之前或之後會發生磷酸化（P）。AR轉運到細胞核中，在那裡會相互之間形成二聚體、與DNA結合併招募共激活因子。靶基因被轉錄（mRNA）繼而被翻譯為蛋白質^[2][3][4][5]。

雄激素受體的主要功能是作為調控基因表達的一種結合DNA的轉錄因子^[10]；然而雄激素受體也有其它方面的功能^[11]。受雄激素調控的基因在男性性表型的發育及維持中起到重要作用。
