一般說明
C2H2 zinc finger (ZNF) proteins (ZFPs) represent the largest family of gene regulators in human. C2H2 ZFPs wrap around DNA via multiple zinc fingers to ensure a stable DNA interaction. Small linker peptides joining adjacent zinc finger modules are critical for the DNA-binding activity of C2H2 ZFPs. The vast majority of linker peptides contain a serine or threonine as their first amino acid residue, phosphorylation of which greatly reduces the DNA binding activity of C2H2 ZFPs. About half of ZFPs contain the highly conserved KRAB repression domain. KRAB family zinc finger proteins (KRAB-ZNF) adopt simple protein architecture where the conserved N-terminal KRAB domain is linked with the sequence-specific DNA-binding domain comprised of tandem arrays of the C2H2 type ZNFs. The KRAB domain directly binds KAP1 and is essential for KRAB-ZNF-mediated gene repression. Upon recruitment to chromatin by KRAB-ZNFs, KAP1 in turn functions as a scaffolding protein for histone- and DNA-modifying enzymes involved in target genes silencing.
特異性
This polyclonal antibody detected strong ZnFL-specific signals in the nuclear fractions from all vertebrate cells tested, although only three weak ZnFL-reactive bands were detected in chicken cell lysates. This antibody did not detect ZNFs in yeast and reacted with only one band in E. coli and a few proteins in Drosophila cell lysates (Addison, J.B., et al. (2015). Cancer Res. 75(2):344-355).

應用
Immunoprecipitation Analysis: A representative lot immunoprecipitated endogenous KRAB-ZNFs from human MDA-MB-231LN breast cancer cells and non-cancer HMLE mammary epithelial cells (Addison, J.B., et al. (2015). Cancer Res. 75(2):344-355).
Western Blotting Analysis: A representative lot detected ZnFL-specific target bands in the nuclear fractions from all vertebrate samples tested, although only three weak ZnFL-reactive bands were detected in chicken cell lysates. This antibody did not detect ZNFs in yeast and reacted with only one band in E. coli and a few proteins in Drosophila cell lysates (Addison, J.B., et al. (2015). Cancer Res. 75(2):344-355).
Anti-HpTGEKP motif, Cat. No. ABE319, is also available for detecting zinc finger linker threonine phosphorylation in Flow cytometry, Immunocytochemistry, Immunoprecipitation, and Western blotting applications.

Understanding transcription factor navigation through the nucleus remains critical for developing targeted therapeutics. The GLI1 transcription factor must maintain maximal Hedgehog pathway output in basal cell carcinomas (BCCs), and we have previously shown that resistant BCCs increase GLI1 deacetylation through
