C2H2 zinc finger proteins (ZFPs) are DNA-binding transcription factors that regulate a variety of biological processes such as cellular growth, differentiation, and proliferation. A zinc finger protein can contain several tandems of clustered zinc finger motifs responsible for DNA binding. However, stable ZFP binding to DNA requires the conserved linker sequences that join adjacent zinc fingers. These linkers participate in wrapping of the ZFP around the double helix of DNA, which is required for efficient binding. Most of the ZFP linkers contain the same amino acid sequence HTGEKP, which has been shown to be phosphorylated at the threonine residue by TOPK/PBK during mitosis. Phosphorylation on the linker sequence of ZFP leads to the inactivation of DNA binding activity.Product Details

- Recommended Usage
Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.5 - 2.5 µg/ml. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
The antibody recognizes the mitotically-phosphorylated form of the HTGEKP conserved motif of C2H2 Zinc finger proteins. This is conserved across most higher eukaryotic species and is found in mitotic cells of human and mouse (and most eukaryotic) species.

- Conserved linker region (HTGEKP) of C2H2 zinc finger proteins.
- The linker region (HTGEKP) of C2H2 zinc finger proteins facilitate stable DNA binding and is highly conserved among these zinc finger proteins. During mitosis, C2H2 zinc finger proteins are phosphorylated on the threonine residue of the linker peptide, which result in the inactivation of their DNA binding activity.
