Androgen receptor coactivators

摘要

Disclosed are androgen receptor-associated proteins, designated ARA24, ARA54, ARA55, and Rb, that have been demonstrated to interact with the androgen receptor to alter levels of androgen receptor-mediated transcriptional activation. Certain of these proteins interact with the androgen receptor in an androgen-dependent manner, whereas certain proteins may induce transcriptional activation in the presence of other ligands, such as E2 or HF. Also disclosed is a method of detecting androgenic or antiandrogenic activity using these proteins in a mammalian two-hybrid transient transfection assay.
