DomainComposed of three domains: a modulating N-terminal domain, a DNA-binding domain and a C-terminal ligand-binding domain.
FunctionIsoform 4: Increases mitochondrial membrane potential and cellular respiration upon stimulation by progesterone.
FunctionIsoform A: inactive in stimulating c-Src/MAPK signaling on hormone stimulation.
FunctionThe 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.
InteractionQ9H467:CUEDC2; NbExp=9; IntAct=EBI-78539, EBI-1248228; P40763:STAT3; NbExp=3; IntAct=EBI-78539, EBI-518675;
PtmPalmitoylated by ZDHHC7 and ZDHHC21. Palmitoylation is required for plasma membrane targeting and for rapid intracellular signaling via ERK and AKT kinases and cAMP generation. {ECO:0000269|PubMed:22031296}.
PtmPhosphorylated on multiple serine sites. Several of these sites are hormone-dependent. Phosphorylation on Ser-294 occurs preferentially on isoform B, is highly hormone-dependent and modulates ubiquitination and sumoylation on Lys-388. Phosphorylation on Ser-102 and Ser-345 also requires induction by hormone. Basal phosphorylation on Ser-81, Ser-162, Ser-190 and Ser-400 is increased in response to progesterone and can be phosphorylated in vitro by the CDK2-A1 complex. Increased levels of phosphorylation on Ser-400 also in the presence of EGF, heregulin, IGF, PMA and FBS. Phosphorylation at this site by CDK2 is ligand-independent, and increases nuclear translocation and transcriptional activity. Phosphorylation at Ser-162 and Ser-294, but not at Ser-190, is impaired during the G(2)/M phase of the cell cycle. Phosphorylation on Ser-345 by ERK1/2 MAPK is required for interaction with SP1. {ECO:0000269|PubMed:10628747, ECO:0000269|PubMed:10655479, ECO:0000269|PubMed:11110801, ECO:0000269|PubMed:15572662, ECO:0000269|PubMed:15798179, ECO:0000269|PubMed:17020914, ECO:0000269|PubMed:17173941, ECO:0000269|PubMed:17347654, ECO:0000269|PubMed:17717077, ECO:0000269|PubMed:18202149, ECO:0000269|PubMed:7476977, ECO:0000269|PubMed:8702648, ECO:0000269|PubMed:9171245}.
PtmSumoylation is hormone-dependent and represses transcriptional activity. Sumoylation on all three sites is enhanced by PIAS3. Desumoylated by SENP1. Sumoylation on Lys-388, the main site of sumoylation, is repressed by ubiquitination on the same site, and modulated by phosphorylation at Ser-294. {ECO:0000269|PubMed:10628747, ECO:0000269|PubMed:10655479, ECO:0000269|PubMed:15798179, ECO:0000269|PubMed:17020914, ECO:0000269|PubMed:17173941, ECO:0000269|PubMed:17347654, ECO:0000269|PubMed:17717077, ECO:0000269|PubMed:18202149, ECO:0000269|PubMed:8702648}.
PtmUbiquitination is hormone-dependent and represses sumoylation on the same site. Promoted by MAPK-mediated phosphorylation on Ser-294. {ECO:0000269|PubMed:10628747, ECO:0000269|PubMed:10655479, ECO:0000269|PubMed:15798179, ECO:0000269|PubMed:17173941, ECO:0000269|PubMed:17717077, ECO:0000269|PubMed:18202149, ECO:0000269|PubMed:8702648}.
SimilarityBelongs to the nuclear hormone receptor family. NR3 subfamily. {ECO:0000305}.
SimilarityContains 1 nuclear receptor DNA-binding domain. {ECO:0000255|PROSITE-ProRule:PRU00407}.
Subcellular LocationIsoform 4: Mitochondrion outer membrane {ECO:0000269|PubMed:23518922}.
Subcellular LocationIsoform A: Nucleus. Cytoplasm. Note=Mainly nuclear.
Subcellular LocationNucleus. Cytoplasm. Note=Nucleoplasmic shuttling is both homone- and cell cycle-dependent. On hormone stimulation, retained in the cytoplasm in the G(1) and G(2)/M phases.
SubunitInteracts with SMARD1 and UNC45A. Interacts with CUEDC2; the interaction promotes ubiquitination, decreases sumoylation, and repesses transcriptional activity. Interacts with PIAS3; the interaction promotes sumoylation of PR in a hormone-dependent manner, inhibits DNA-binding, and alters nuclear export. Interacts with SP1; the interaction requires ligand-induced phosphorylation on Ser-345 by ERK1/2 MAPK. Interacts with PRMT2. {ECO:0000269|PubMed:12039952, ECO:0000269|PubMed:12917342, ECO:0000269|PubMed:16478993, ECO:0000269|PubMed:17020914, ECO:0000269|PubMed:17347654, ECO:0000269|PubMed:18202149}.
