Anti-SETDB1 antibody produced in rabbit

The gene SET domain bifurcated-1 (SETDB1) is located in human chromosome 1 (1q21). The encoded protein contains a DNA methyl binding domain and catalytic SET domain at the N- and C-terminus respectively. In non­-small lung cancer cells SETDB1 is present mainly in the nucleus, with additional cytoplasmic expression. Similarly, mouse embryos showed SETDB1 signal in the nucleus.

SET domain bifurcated-1 (SETDB1) is responsible for methylation of histone 3 lysine-9 in euchromatic region, resulting in a repressed transcription mark. During DNA replication, it is recruited by Methyl-CpG-binding domain protein-1 (MBD1) and forms a replication coupled complex with chromatin assemble factor CAF-1 to methylate lysine-9 at the newly deposited histone 3. The gene is up-regulated in glioma tissues, melanomas, non-small and small lung cancers. SETDB1 undergoes gene amplification in lung tumorigenesis. Higher expression causes stimulation of WNT-β-catenin pathway and down-regulation of P53 expression, resulting in enhanced non-small cell lung cancer growth. Role of SETDB1 in cancer is also suggested by its association with the promyelocytic nuclear leukemia-nuclear bodies and increased expression in broncoepithelial cells. SETDB1 is involved in proviral silencing during embryogenesis when DNA methylation is dynamically reprogrammed.

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
