Androgen Receptor (AR)
Androgen receptor (AR) mediates the effects of androgens that are responsible for diverse biological functions, such as development and maintenance of the male reproductive system, as well as involvement in disease states, such as prostate cancer (PCa) (for a review, see Brinkmann (2011)). AR is a ligand-activated transcription factor (TF) that belongs to the steroid hormone receptor (SHR) family within the nuclear receptor (NR) superfamily of TFs (for a review, see Huang et al. (2010)). In addition to AR, the SHR family contains the glucocorticoid receptor (GR), mineralocorticoid receptor (MR), progesterone receptor (PR), and the estrogen receptor (ER). SHRs are structurally and functionally related and mediate the action of steroid hormones that affect nearly all aspects of development and homeostasis; they are also implicated in a number of...
