Secreted frizzled-related protein 5, Frizzled-related protein 1b, FRP-1b, Secreted apoptosis-related protein 3, SARP-3
Secreted Frizzled Related Proteins (sFRPs) are a family of glycosylated Wnt antagonists that inhibit Wnt signaling, either by directly binding to Wnt proteins to prevent their binding to Frizzled (Fz) family receptor proteins or by forming non-functional
