Scientific Background: p23 (Prostaglandin E synthase 3; PTGES3) is a highly conserved ubiquitous protein, known to have an important function as a cochaperone for the HSP90 chaperoning system (1), and it is an enzyme that catalyzes the conversion of prostaglandin endoperoxide(H2 (PGH2) to prostaglandin E2 (PGE2). Studies have revealed that it is a small protein (18 to 25 kDa) with a simple structure (2, 3). p23 does not have any structural homology with any other known proteins (1). p23 was first discovered as a part of the HSP90-progesterone receptor complex along with HSP70, p54 and p50 (1). p23 is a phosphor-protein, which is highly acidic and has an aspartic acid-rich c-terminal domain (1). Numerous studies have found p23 to be associated with other client proteins like Fes tyrosine kinase (4), the heme regulated kinase HRI (5), hsf1 transcription factor (4), aryl hydrocarbon receptor (4), telomerase (6), and Hepadnavirus reverse transcriptase (7). It also plays a role in telomerase activation, contributing to cellular immortalization. p23 is thought to be involved in the adenosine triphosphate–mediated HSP90 binding of client proteins (8). Since many HSP90 client proteins are involved in oncogenic survival signalling, p23 may be a promising target in leukemic apoptosis (9). HSP90 and its co-chaperone p23 are among the emerging anti- tumour targets in oncology. This description may include information annotated by UniProt and/or Google AI.
