fz4

Gene
fz4
Protein
Frizzled-4
Organism
Drosophila melanogaster
Length
705 amino acids
Function
Receptor for Wnt proteins. Most of frizzled receptors are coupled to the beta-catenin canonical signaling pathway, which leads to the activation of disheveled proteins, inhibition of GSK-3 kinase, nuclear accumulation of beta-catenin and activation of Wnt target genes. A second signaling pathway involving PKC and calcium fluxes has been seen for some family members, but it is not yet clear if it represents a distinct pathway or if it can be integrated in the canonical pathway, as PKC seems to be required for Wnt-mediated inactivation of GSK-3 kinase. Both pathways seem to involve interactions with G-proteins. May be involved in transduction and intercellular transmission of polarity information during tissue morphogenesis and/or in differentiated tissues. Required to coordinate the cytoskeletons of epidermal cells to produce a parallel array of cuticular hairs and bristles.
Similarity
Belongs to the G-protein coupled receptor Fz/Smo family.
