Protein Information
Synonyms P23, TEBP
Function Cytosolic prostaglandin synthase that catalyzes the oxidoreduction of prostaglandin endoperoxide H2 (PGH2) to prostaglandin E2 (PGE2) (PubMed:10922363). Molecular chaperone that localizes to genomic response elements in a hormone-dependent manner and disrupts receptor-mediated transcriptional activation, by promoting disassembly of transcriptional regulatory complexes (PubMed:11274138, PubMed:12077419). Facilitates HIF alpha proteins hydroxylation via interaction with EGLN1/PHD2, leading to recruit EGLN1/PHD2 to the HSP90 pathway (PubMed:24711448).
Cellular Location Cytoplasm {ECO:0000250|UniProtKB:Q3ZBF7}.

Prostaglandin E synthase-3 belongs to p23/wos2 family. It is ubiquitously expressed. As one of the two isoforms of the terminal enzymes catalyzing the final step of EG2 biosynthesis, prostaglandin E synthase-3 predominantly converts COX-1-derived PGH2 to PGE2 (1). It is an evolutionarily conserved protein that functions as a component of the Hsp90-based molecular chaperone complex (2). It binds to telomerase and to the progesterone receptor (3). It localizes to genomic response elements in a hormone-dependent manner and represses receptor-mediated transcriptional activation by promoting disassembly of transcriptional regulatory complexes (4).
