FRP, FRP1, FrzA, FRP-1, SARP2, Secreted frizzled-related protein 1, sFRP-1, Secreted apoptosis-related protein 2, SARP-2, SFRP1
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. SFRP1 decreases intracellular beta-catenin leve
