Anti-Krueppel-like factor 8 KLF8 Antibody Picoband®

KLF8 (Krueppel-like factor 8) is a protein that in humans is encoded by the KLF8 gene. It is also named as ZNF741, or BKLF3. Kruppel-like factor proteins, including KLF8, all contain a characteristic C-terminal DNA-binding domain containing 3 Kruppel-like zinc fingers, and they all recognize CACCC and GC boxes present in promoters and enhancers. The International Radiation Hybrid Mapping Consortium mapped the KLF8 gene to the X chromosome (WI-18614) . Suske et al. (2005) stated that the human KLF8 gene maps to chromosome Xp11.21, and the mouse Klf8 gene to chromosome XF3. van Vliet et al. (2000) identified a cDNA encoding KLF8, also called ZNF741. Expression of KLF8 or only its zinc fingers showed that the fingers could bind to a CACCC box. Sequence analysis predicted that the 359-amino acid protein contains a nuclear localization signal upstream of the zinc fingers, a valine-rich hydrophobic stretch, and a pro-val-asp-leu-ser (PVDLS) motif. Yeast 2-hybrid and GST pull-down analysis demonstrated that CTBP2 interacts with KLF8 through the PVDLS motif.

Transcriptional repressor and activator. Binds to CACCC- boxes promoter elements. Also binds the GT-box of cyclin D1 promoter and mediates cell cycle progression at G (1) phase as a downstream target of focal adhesion kinase (FAK) . .
