PTGFRN [ENSP00000376899]
 
prostaglandin F2 receptor negative regulator; Inhibits the binding of prostaglandin F2-alpha (PGF2- alpha) to its specific FP receptor, by decreasing the receptor number rather than the affinity constant. Functional coupling with the prostaglandin F2-alpha receptor seems to occur (By similarity)
CD9 [ENSP00000009180]
 
CD9 molecule; Involved in platelet activation and aggregation. Regulates paranodal junction formation. Involved in cell adhesion, cell motility and tumor metastasis. Required for sperm-egg fusion
