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. SFRP1 decreases intracellular beta-catenin levels (By similarity). Has antiproliferative effects on vascular cells, in vitro and in vivo, and can induce, in vivo, an angiogenic response. In vascular cell cycle, delays the G1 phase and entry into the S phase (By similarity). In kidney development, inhibits tubule formation and bud growth in metanephroi (By similarity). Inhibits WNT1/WNT4-mediated TCF-dependent transcription. -
Tissue specificity
Widely expressed. Absent from lung, liver and peripheral blood leukocytes. Highest levels in heart and fetal kidney. Also expressed in testis, ovary, fetal brain and lung, leiomyomal cells, myometrial cells and vascular smooth muscle cells. Expressed in foreskin fibroblasts and in keratinocytes. -
Sequence similarities
Belongs to the secreted frizzled-related protein (sFRP) family.
Contains 1 FZ (frizzled) domain.
Contains 1 NTR domain. -
Domain
The FZ domain is involved in binding with Wnt ligands. -
Cellular localization
Secreted. Cell membrane or extracellular matrix-associated. Released by heparin-binding. - Information by UniProt
