Target Information

The progesterone receptor (PR) is a member of the steroid family of nuclear receptors. It mediates the physiological effects of progesterone, which plays a central role in reproductive events associated with pregnancy establishment and maintenance.
PR exists as two isoforms: a 94 kDa protein (Form A) and a 120 kDa protein (Form B), resulting from alternative translation initiation sites. PR-B is the transcriptionally active form responsible for activating genes involved in endometrial maintenance, pregnancy, and inhibition of ovulation.
PR-A is identical to PR-B except for a 165 amino acid deletion at the N-terminus, exposing a 140 amino acid inhibitory domain (ID) that represses steroid hormone transcriptional activity.
In its inactive state, PgR forms a multiprotein complex including heat shock proteins and immunophilins. Upon progesterone binding, the receptor undergoes a conformational change, enabling dimerization and binding to progesterone response elements (PRE), leading to transcriptional activation.
A null mutation in the PGR gene leads to pleiotropic reproductive abnormalities.
