SFRP4

Domain

The FZ domain is involved in binding with Wnt ligands.

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 (By similarity). 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 (By similarity). Has phosphaturic effects by specifically inhibiting sodium-dependent phosphate uptake (PubMed:12952927).

Involvement in disease

Pyle disease

PYL

A disorder characterized by cortical-bone thinning, limb deformity, bone fragility and fractures.

None

The disease is caused by variants affecting the gene represented in this entry.

Sequence similarities

Belongs to the secreted frizzled-related protein (sFRP) family.

Tissue specificity

Expressed in mesenchymal cells. Highly expressed in the stroma of proliferative endometrium. Expressed in cardiomyocytes. Shows moderate to strong expression in ovarian tumors with expression increasing as the tumor stage increases. In ovarian tumors, expression levels are inversely correlated with expression of CTNNB1 (at protein level).

Cellular localization

  • Secreted
  • Cytoplasmic in ovarian tumor cells.
