Purified recombinant Human sFRP1 protein Expression System: HeLa cells Bioactivity: Determined by its ability to inhibit BMP-2 proliferation effect of ATDC-5 cells. The expected ED50 is 0.3-0.5 µg/mL.
Secreted Frizzled Related Proteins (sFRPs) modulate WNT signaling by binding directly to WNT proteins in a manner that affects their receptor binding and signaling capabilities. sFRP-1 is a widely distributed protein that can bind directly to WNT1, WNT2, and possibly other WNT proteins, and generally exerts anti-proliferative effects consistent with activity as a WNT antagonist. It also inhibits apoptosis and has been found to be down-regulated in many solid tumors, but up-regulated in uterine leiomyomas. Alternative Names: SFRP-1 protein, Secreted Frizzled Related Protein 1 protein, sFRP-1 protein, sFRP 1, sFRP 1 protein, Secreted Apoptosis Related Protein-2 protein, sFRP-1, sFRP1, Soluble Frizzled Related Protein-1 protein, SARP-2 protein
