Anti-Gli3

0.5mg/ml if reconstituted with 0.2ml sterile DI water. Gli-kruppel family member 3 is a member of the zinc finger family related to Kruppel, a protein family that is known to regulate development in Drosophila. The gene is expressed as an 8.5-kb mRNA in tissues such as testis, myometrium, placenta, and lung, and the protein product (relative molecular mass, 190,000D) shows sequence-specific DNA binding. Gli3 is homologous to the Drosophila cubitus interruptus (ci) gene product(Ci), which regulates the Patched (pct), Gooseberry (gsb), and Decapentaplegic (dpp) genes. PKA-dependent processing of vertebrate Gli3 in developing limb generates a potent repressor in a manner antagonized by apparent long-range signaling from posteriorly localized Sonic hedgehog protein. The high relative abundance and potency of Gli3 repressor suggested specialization of the protein and its products for negative hedgehog pathway regulation. Protein function: Has a dual function as a transcriptional activator and a repressor of the sonic hedgehog (Shh) pathway, and plays a role in limb development. The full-length GLI3 form (GLI3FL) after phosphorylation and nuclear translocation, acts as an activator (GLI3A) while GLI3R, its C-terminally truncated form, acts as a repressor. A proper balance between the GLI3 activator and the repressor GLI3R, rather than the repressor gradient itself or the activator/repressor ratio gradient, specifies limb digit number and identity. In concert with TRPS1, plays a role in regulating the size of the zone of distal chondrocytes, in restricting the zone of PTHLH expression in distal cells and in activating chondrocyte proliferation.
