CC   -!- FUNCTION: Soluble frizzled-related proteins (sFRPS) function as
CC       modulators of Wnt signaling through direct interaction with Wnts. They
CC       have a role in regulating cell growth and differentiation in specific
CC       cell types. SFRP1 decreases intracellular beta-catenin levels (By
CC       similarity). Has antiproliferative effects on vascular cells, in vitro
CC       and in vivo, and can induce, in vivo, an angiogenic response. In
CC       vascular cell cycle, delays the G1 phase and entry into the S phase (By
CC       similarity). In kidney development, inhibits tubule formation and bud
CC       growth in metanephroi (By similarity). Inhibits WNT1/WNT4-mediated TCF-
CC       dependent transcription. {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with WNT1, WNT2 and FRZD6. Interacts with WNT4, WNT8
CC       and MYOC (By similarity). {ECO:0000250}.
CC   -!- INTERACTION:
CC       Q8N474; O60353: FZD6; NbExp=3; IntAct=EBI-3940687, EBI-8754490;
CC       Q8N474; Q8N661: TMEM86B; NbExp=3; IntAct=EBI-3940687, EBI-2548832;
CC   -!- SUBCELLULAR LOCATION: Secreted. Note=Cell membrane or extracellular
CC       matrix-associated. Released by heparin-binding.
CC   -!- TISSUE SPECIFICITY: Widely expressed. Absent from lung, liver and
CC       peripheral blood leukocytes. Highest levels in heart and fetal kidney.
CC       Also expressed in testis, ovary, fetal brain and lung, leiomyomal
CC       cells, myometrial cells and vascular smooth muscle cells. Expressed in
CC       foreskin fibroblasts and in keratinocytes.
CC       {ECO:0000269|PubMed:9391078}.
CC   -!- INDUCTION: Down-regulated in colorectal and breast tumors. Up-regulated
CC       in uterine leiomyomas under high estrogenic conditions. Expression, in
CC       leiomyomal cells, also increased both under hypoxic and serum
CC       deprivation conditions. {ECO:0000269|PubMed:11932307,
CC       ECO:0000269|PubMed:9724099}.
CC   -!- DOMAIN: The FZ domain is involved in binding with Wnt ligands.
CC       {ECO:0000250}.
CC   -!- MISCELLANEOUS: May have therapeutic use in cardiac surgery.
CC   -!- SIMILARITY: Belongs to the secreted frizzled-related protein (sFRP)
CC       family. {ECO:0000305}.
