Reactivation of the androgen receptor from murine preputial gland by thioredoxin or GSH.
The androgen receptor from murine preputial gland was inactivated by density gradient centrifugation, affinity chromatography and isoelectric focusing. The hormone binding of the receptor could be partially restored (roughly 40%) by the thioredoxin-thioredoxinreductase system, by thioredoxin plus dithiothreitol or by glutathione. Dithiothreitol, by itself, was unable to reactivate the androgen receptor. These findings show that the receptor inactivation is, at least partially, due to thiol group oxidation and removal of SH-reducing and/or -stabilizing substances from the receptor during purification.
