Background
The human Progesterone Receptor (PgR) is a member of the steroid family of nuclear receptors. PgR is found as a 120kDa protein (Form B) or a 94kDa protein (Form A) due to the use of alternative translation initiation sites. In its inactive state, PgR forms a multiprotein complex which includes heat shock proteins and immunophins. Upon binding of progesterone hormone to its receptor, there is a conformational change that allows dimerization and binding of the receptor to progesterone response elements (PRE) sequences, resulting in activated transcription. When bound to DNA, PgR can positively or negatively regulate gene transcription through the recruitment of coactivator (e.g. SRC-1) or corepressor (e.g. NCoR) proteins. PgR is phosphorylated on multiple serine residues through distinct groups of sites regulated by hormone and different kinases.
