Anti-CLLD8/SETDB2 Picoband® Antibody

SET domain bifurcated histone lysine methyltransferase 2 is a protein in humans encoded by the SETDB2 gene. It is mapped to 13q14.2. This gene encodes a member of a family of proteins that contain a methyl-CpG-binding domain (MBD) and a SET domain and function as histone methyltransferases. This protein is recruited to heterochromatin and plays a role in the regulation of chromosome segregation. This region is commonly deleted in chronic lymphocytic leukemia. Naturally-occuring readthrough transcription occurs from this gene to the downstream PHF11 (PHD finger protein 11) gene. Alternative splicing results in multiple transcript variants.

A synthetic peptide corresponding to a sequence at the C-terminus of human CLLD8/SETDB2, which shares 96.6% and 93.1% amino acid (aa) sequence identity with mouse and rat CLLD8/SETDB2, respectively.

Histone methyltransferase involved in left-right axis specification in early development and mitosis. Specifically trimethylates 'Lys-9' of histone H3 (H3K9me3) . H3K9me3 is a specific tag for epigenetic transcriptional repression that recruits HP1 (CBX1, CBX3 and/or CBX5) proteins to methylated histones. Contributes to H3K9me3 in both the interspersed repetitive elements and centromere-associated repeats. Plays a role in chromosome condensation and segregation during mitosis.
