Mouse FPRP/PTGFRN Biotinylated Antibody

FPRP (F_{2 alpha} Prostaglandin receptor Regulatory Protein; also CD315, EWI-F and CD9 partner-1/P-1) is a 130 kDa type I transmembrane (TM) glycoprotein member of the EWI subfamily, Ig superfamily of molecules. It associates with the 7-TM prostaglandin F_{2 alpha}  receptor, inhibiting its activity. It also forms complexes with 4-TM CD9 and CD81, linking these molecules to the intracellular actin cytoskeleton. Mature mouse FPRP is 858 amino acids (aa) in length. Its extracellular domain (ECD) contains six C2-type Ig-like domains (aa 22‑813) plus a Pro-Thr-Glu-Leu ER retention signal. The ECD of mouse FPRP (aa 22‑832) shares 89% and 98% aa identity with the ECD of human and rat FPRP, respectively.
