GLI3
Zinc finger protein GLI3 is a protein that in humans is encoded by the ''GLI3'' gene.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=2737 )〕 This gene encodes a protein that belongs to the C2H2-type zinc finger proteins subclass of the Gli family. They are characterized as DNA-binding transcription factors and are mediators of Sonic hedgehog (Shh) signaling. The protein encoded by this gene localizes in the cytoplasm and activates patched Drosophila homolog (PTCH1) gene expression. It is also thought to play a role during embryogenesis.〔 == Role in development == Gli3 is a known transcriptional repressor but may also have a positive transcriptional function. Gli3 represses dHand and Gremlin, which are involved in developing digits. There is evidence that Shh-controlled processing (e.g., cleavage) regulates transcriptional activity of Gli3 similarly to that of CI.〔 Gli3 mutant mice have many abnormalities including CNS and lung defects and limb polydactyly.
