Secreted frizzled-related protein 4 (SFRP4)

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 (By similarity).

SFRP4 plays a role in bone morphogenesis. May also function as a regulator of adult uterine morphology and function.
