Anti-GLI2 Antibody Picoband® Fluoro488 Conjugated

GLI2 (Gli-Kruppel Family Member 2), also called ONCOGENE GLI2, is a protein that in humans is encoded by the GLI2 gene. Sequencing of GLI cDNA clones showed the presence of 5 tandem zinc fingers connected by histidine-cysteine links, which indicated that the gene belongs to the family of zinc finger genes related to Kruppel (Kr) . The Drosophila gene Kr is a member of the gap class of segmentation genes; thoracic and anterior abdominal segments fail to form in Kr mutant embryos. By fluorescence in situ hybridization, Matsumoto et al. (1996) refined the assignment of the GLI2 gene to chromosome 2q14. Roessler et al. (2005) showed that GLI2-delta-N exhibited potent transcriptional activity in vivo: overexpression in mouse skin led to the formation of hedgehog-independent epithelial downgrowths resembling basal cell carcinomas, which in humans are associated with constitutive hedgehog signaling.

Expressed in breast cancers. Isoform 1 and isoform 4 are expressed in HTLV-1-infected T-cell lines. Isoform 1 and isoform 2 are strongly expressed in HTLV-1-infected T-cell lines. Isoform 3 and isoform 4 are weakly expressed in HTLV-1-infected T-cell lines.

Functions as transcription regulator in the hedgehog (Hh) pathway. Functions as transcriptional activator. May also function as transcriptional repressor. Requires STK36 for full transcriptional activator activity. Required for normal embryonic development. Act as transcriptional activators in T-cell leukemia virus type 1 (HTLV-1) -infected cells in a Tax-dependent manner. Bind to the DNA sequence 5'-GAACCACCCA-3' which is part of the Tax-responsive element (TRE-2S) regulatory element that augments the Tax-dependent enhancer of HTLV-1. Are involved in the smoothened (SHH) signaling pathway. Acts as a transcriptional repressor.
