Anti-Smad Interacting Protein 1/ZEB2 Antibody Picoband® Fluoro647 Conjugated

ZEB2 (Zinc finger E-box-binding homeobox2), also known as SIP1or ZINC FINGER HOMEOBOX 1B (ZFHX1B), is a protein that in humans is encoded by the ZEB2 gene. The ZEB2 gene is a member of the ZEB1/Drosophila Zfh1 family of 2-handed zinc finger/homeodomain proteins and functions as a DNA-binding transcriptional repressor that interacts with activated SMADs, the transducers of TGF-beta signaling, and interacts with the nucleosome remodeling and histone deacetylation (NURD) complex. By radiation hybrid analysis, Nagase et al. (1998) mapped the ZEB2 gene to chromosome 2. Wakamatsu et al. (2001) mapped the ZEB2 gene to chromosome 2q22. Vandewalle et al. (2005) showed that expression of mouse Sip1 in human epithelial cells caused a morphologic change from an epithelial to a mesenchymal phenotype. Expression of SNAI1 in epithelial cells triggers an epithelial-mesenchyme transition. Beltran et al. (2008) showed that synthesis of ZEB2 was upregulated following SNAI1 expression in human cell lines.
