The function of Ensembl gene identifier ENSG00000106483 (SFRP4, secreted frizzled related protein 4) is as follows. 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). {ECO:0000250|UniProtKB:Q9JLS4, ECO:0000250|UniProtKB:Q9Z1N6, ECO:0000269|PubMed:12952927}.
