Previous GeneCards Identifiers for FZD7 Gene
Members of the 'frizzled' gene family encode 7-transmembrane domain proteins that are receptors for Wnt signaling proteins. The FZD7 protein contains an N-terminal signal sequence, 10 cysteine residues typical of the cysteine-rich extracellular domain of Fz family members, 7 putative transmembrane domains, and an intracellular C-terminal tail with a PDZ domain-binding motif. FZD7 gene expression may downregulate APC function and enhance beta-catenin-mediated signals in poorly differentiated human esophageal carcinomas. [provided by RefSeq, Jul 2008]
GeneCards Summary for FZD7 Gene
FZD7 (Frizzled Class Receptor 7) is a Protein Coding gene. Diseases associated with FZD7 include Hepatocellular Carcinoma and Exudative Vitreoretinopathy. Among its related pathways are Presynaptic function of Kainate receptors and Reelin Pathway (Cajal-Retzius cells). Gene Ontology (GO) annotations related to this gene include G-protein coupled receptor activity and PDZ domain binding. An important paralog of this gene is FZD2.
UniProtKB/Swiss-Prot for FZD7 Gene
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.
