|Secreted Frizzled Related Protein‑3 (sFRP‑3), also known as FRZB, belongs to a family of Wnt-binding proteins with homology to the ligand‑binding domain of the Frizzled receptors. sFRPs 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. Mature human sFRP‑3 shares 93% aa sequence identity with mouse and rat sFRP‑3. It neutralizes the bioactivity of Wnt‑1, ‑5a, ‑9a, Xenopus Xwnt‑8, and EGF (5‑8). sFRP‑3 regulates somitic myogenesis and osteoblast differentiation as well as morphogenesis of the cochlear epithelium, hair follicle, and cardiac atrioventricular cushion. sFRP‑3 also functions as a tumor suppressor in a variety of cancers including melanoma, medulloblastoma, soft tissue sarcoma, and androgen‑independent prostate cancer. It inhibits epithelial-mesenchymal transition, tumor growth and invasion, and the activity of MMP‑2 and MMP‑9. In contrast, it can promote tumor growth and angiogenesis in renal cancer.
