Anti-KDM1B Antibody

Flavin-dependent histone demethylases regulate histone lysine methylation, an epigenetic mark that regulates gene expression and chromatin function (reviewed in 1) . KDM1B is a recently identified histone H3K4 demethylase that is required to establish maternal genomic imprints; targeted disruption of the KDM1B gene in mice led to lethality in their embryos, suggesting demethylation of H3K4 is critical for establishing the DNA methylation imprints (2) . KDM1B has also been shown to play a role in the transcription elongation in several genes (3) .

KDM1B antibody was raised against a 17 amino acid peptide near the amino terminus of human KDM1B. The immunogen is located within amino acids 80 - 130 of KDM1B.

Histone demethylase that demethylates 'Lys-4' of histone H3, a specific tag for epigenetic transcriptional activation, thereby acting as a corepressor. Required for de novo DNA methylation of a subset of imprinted genes during oogenesis. Acts by oxidizing the substrate by FAD to generate the corresponding imine that is subsequently hydrolyzed. Demethylates both mono- and di-methylated 'Lys-4' of histone H3. Has no effect on tri- methylated 'Lys-4', mono-, di- or tri-methylated 'Lys-9', mono-, di- or tri-methylated 'Lys-27', mono-, di- or tri-methylated 'Lys- 36' of histone H3, or on mono-, di- or tri-methylated 'Lys-20' of histone H4.
