Recombinant Human Secreted frizzled-related protein 1 (SFRP1)

Uniprot Id

Q8N474

Target Species

Human

Target Name

SFRP1

Target Full Name

Secreted frizzled-related protein 1

Target 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. 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. In kidney development, inhibits tubule formation and bud growth in metanephroi. Inhibits WNT1/WNT4-mediated TCF-dependent transcription.

Target Subcellular Location

Secreted. Note=Cell membrane or extracellular matrix-associated. Released by heparin-binding.

Target Protein Families

Secreted frizzled-related protein (sFRP) family

Target Background

This gene encodes a member of the SFRP family that contains a cysteine-rich domain homologous to the putative Wnt-binding site of Frizzled proteins. Members of this family act as soluble modulators of Wnt signaling; epigenetic silencing of SFRP genes leads to deregulated activation of the Wnt-pathway which is associated with cancer. This gene may also be involved in determining the polarity of photoreceptor cells in the retina.
