Frizzled-4 (Fz-4) is a protein that in humans is encoded by the FZD4 gene.[5][6][7] Fz-4 has also been designated as CD344 (cluster of differentiation 344).

Function

This gene is a member of the frizzled gene family. Members of this family encode seven-transmembrane domain proteins that are receptors for the Wingless type MMTV integration site family of signaling proteins. Frizzled-4 is the only representative of frizzled family members that binds strongly an additional ligand Norrin that is functionally similar but structurally different from Wingless type proteins.[8] FZD4 signaling induced by Norrin regulates vascular development of vertebrate retina and controls important blood vessels in the ear. Most frizzled receptors are coupled to the beta-catenin canonical signaling pathway. This protein may play a role as a positive regulator of the Wingless type MMTV integration site signaling pathway. A transcript variant retaining intronic sequence and encoding a shorter isoform has been described, however, its expression is not supported by other experimental evidence.[7]
