Frizzled-6 is a protein that in humans is encoded by the FZD6 gene.^[1]^[2]^[3]

Members of the 'frizzled' gene family encode 7-transmembrane domain proteins that are receptors for WNT signaling proteins. The FZD6 protein contains a signal peptide, a cysteine-rich domain in the N-terminal extracellular region, and 7 transmembrane domains. However, unlike many other FZD family members, FDZ6 does not contain a C-terminal PDZ domain-binding motif.^[3] The FZD6 protein is believed to be the receptor for the WNT4 ligand.^[4]

Phenotypes

In 2004, researchers at the Howard Hughes Medical Institute showed that FZD6 controls hair patterning in mice,^[3] and its human homologue is understood to play a part in the formation of hair whorls and cowlicks.

Interactions

FZD6 has been shown to interact with Secreted frizzled-related protein 1.^[5]
