Anti-Norrin (Norrie Disease Protein)

Norrin is a secreted protein that has a C-terminal cysteine-knot motif. Although Norrin is unrelated to Wnt family proteins, it is a Frizzled-4-specific ligand that activates the canonical Wnt pathway through Frizzled-4 and LRP5 (LDL receptor-related protein). Mutations in Norrin are associated with Norrie disease and X-linked familial exudative vitroretinopathy. The amino acid sequence of human Norrin is 100% and 94% identical to rhesus macaque and mouse Norrin, respectively. Applications: Suitable for use in ELISA and Western Blot.
