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 the establishment and maintenance of pregnancy.
PR exists as a 94 kDa protein (Form A) or a 120 kDa protein (Form B) due to alternative translation initiation sites. PR-B is the transcriptionally active form, responsible for activating genes involved in endometrium maintenance, pregnancy, and inhibition of ovulation.
PR-A differs from PR-B by a 165 amino acid deletion at the N-terminus, exposing a 140 amino acid inhibitory domain that represses steroid hormone transcriptional activity.
In its inactive state, PgR forms a multiprotein complex including heat shock proteins and immunophilins. Upon progesterone binding, conformational changes allow receptor dimerization and binding to progesterone response elements (PRE), activating transcription.
A null mutation in the PGR gene leads to pleiotropic reproductive abnormalities.
