Prostaglandin F2 Receptor Negative Regulator (PTGFRN) Antibody

Background

Prostaglandin F2 receptor inhibitor (PTGFRN), also known as CD315 or FPRP (Fas-associated protein response-related protein), is a transmembrane protein associated with prostaglandin receptor signaling. PTGFRN is known primarily for its ability to modulate prostaglandin F2 alpha (PGF2α) receptor function, thereby impacting prostaglandin signaling pathways involved in inflammatory responses, immune modulation, and reproductive processes. PTGFRN doesn’t directly bind prostaglandins but instead influences PGF2α receptor function indirectly, regulating cellular responses to prostaglandins by modifying receptor sensitivity and availability on the cell surface. PTGFRN has a wide tissue distribution and is expressed in cells of the immune system, cardiovascular tissues, reproductive organs, and certain epithelial tissues. Its role extends beyond prostaglandin modulation, as it’s also involved in various cellular processes including cell adhesion, migration, and interactions with other membrane proteins, such as tetraspanins. PTGFRN is therefore relevant in inflammatory diseases, reproductive health, cardiovascular function, and potentially in cancer.
