Anti-Androgen Receptor (Dihydrotestosterone Receptor, Nuclear Receptor Subfamily 3 Group C Member 4,

AR (Androgen receptor) is a 99kD (predicted) member of the NR3 subfamily, nuclear hormone receptor family of proteins. Due to a high number of Gln and Pro residues, it runs anomalously at 100-120kD in SDS-Page. It is widely expressed, being found in neurons, endothelial cells, osteoblasts, chrondrocytes, mascrophages, adipocytes, and prostate epithelium. Human AR is 919aa in length. It contains three discrete domains: a "modulating" N-terminus (aa1-553) that is rich in Gln, Pro and Gly, a Zn-finger DNA-binding region (aa554-635), and a ligand-binding domain (aa672-917). AR is highly polymorphic at the N-terminus, with total Gln and Gly residues differing by seven or more residues among individuals. Multiple potential splice forms exist, including an alternative start site at Met189 and a sevenaa substitution foraa1-538 that generates a 45kD isoform. AR does homodimerize, apparently with multiple isotypes. Overaa661-920, human and mouse are identical inaa sequence. Applications: Suitable for use in Western Blot and ELISA. Other applications not tested. Recommended Dilutions: Western Blot: 1ug/ml, ELISA: 0.5-1ug/ml, Optimal dilutions to be determined by the researcher.
