Recombinant Human sFRP-1 Protein, CF

This product is produced by and ships from R&D Systems, Inc., a Bio-Techne brand.

Secreted Frizzled Related Protein-1 (sFRP-1), also known as SARP-2, FRP, and FrzA, belongs to a family of Wnt-binding proteins with homology to the ligand-binding domain of the Frizzled transmembrane Wnt receptors. The sFRP proteins are approximately 30-35 kDa in size and contain an N-terminal Frizzled-like domain with 10 conserved cysteines and a Netrin-like C-terminal domain (1-3). Mature human sFRP-1 shares 97% and 96% amino acid sequence identity with mouse and rat sFRP-1, respectively. It binds to Wnt-1, -2, -3a, and -4 and prevents their activation of canonical beta-catenin signaling (4-7). sFRP-1 is up-regulated in the ischemic heart where it limits inflammation and the severity of tissue damage following myocardial infarction (8-10). During angiogenesis it induces endothelial cell migration, tube formation, and vessel formation (11). sFRP-1 is expressed by bone marrow stromal cells and osteoclasts (12). It binds to TRANCE/RANK Ligand, inhibits osteoclast and osteoblast formation and survival, and inhibits the formation of trabecular bone (13, 14). sFRP-1 additionally restricts kidney tubule formation (7), the inflammatory activation of leukocytes (10), early B lymphoid progression (12), and vitreous fluid outflow in the eye (15).
