| Specificity: |
This kit recognizes Human SFRP4 in samples. No significant cross-reactivity or interference between Human SFRP4 and analogues was observed. |
| Sample Type: |
Serum, plasma and other biological fluids |
| Function | Soluble frizzled-related proteins (sFRPS) function as modulators of Wnt signaling through direct interaction with Wnts. They have a role in regulating cell growth and differentiation in specific cell types. SFRP4 plays a role in bone morphogenesis. May also act as a regulator of adult uterine morphology and function. May also increase apoptosis during ovulation possibly through modulation of FZ1/FZ4/WNT4 signaling. Has phosphaturic effects by specifically inhibiting sodium-dependent phosphate uptake. |
