[[http://www.uniprot.org/uniprot/PRGR_HUMAN PRGR_HUMAN]] The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Progesterone receptor isoform B (PRB) is involved activation of c-SRC/MAPK signaling on hormone stimulation.<ref>PMID:15572662</ref> <ref>PMID:15798179</ref> <ref>PMID:17020914</ref> <ref>PMID:17347654</ref> <ref>PMID:17717077</ref> <ref>PMID:17173941</ref> <ref>PMID:18202149</ref>   Isoform A is inactive in stimulating c-Src/MAPK signaling on hormone stimulation.<ref>PMID:15572662</ref> <ref>PMID:15798179</ref> <ref>PMID:17020914</ref> <ref>PMID:17347654</ref> <ref>PMID:17717077</ref> <ref>PMID:17173941</ref> <ref>PMID:18202149</ref>

== Publication Abstract from PubMed ==
The progesterone receptor is able to bind to a large number and variety of ligands that elicit a broad range of transcriptional responses ranging from full agonism to full antagonism and numerous mixed profiles inbetween. We describe here two new progesterone receptor ligand binding domain x-ray structures bound to compounds from a structurally related but functionally divergent series, which show different binding modes corresponding to their agonistic or antagonistic nature. In addition, we present a third progesterone receptor ligand binding domain dimer bound to an agonist in monomer A and an antagonist in monomer B, which display binding modes in agreement with the earlier observation that agonists and antagonists from this series adopt different binding modes.
