Description
Histone H3 is a nuclear protein and a component of the nucleosome core, a basic unit of chromatin, that is essential for organizing genomic DNA in eukaryotic nuclei.1 It is a globular protein that contains an unstructured N-terminal tail that extends outside of the nucleosome core and is subject to various post-translational modifications (PTMs), including methylation, phosphorylation, acetylation, and citrullination.1,2 Trimethylation of histone H3 at lysine 79 (H3K79Me3) is found at promoter regions of both active and silenced genes in human CD4+ T cells and positively correlates with transcriptional repression.3 H3K79Me3 is also found at pericentromeric heterochromatin in mouse oocytes and somatic cells.4 Levels of H3K79Me3 are decreased in human tumor tissue compared to non-cancerous tissue.5 Cayman’s Histone H3K79Me3 Monoclonal Antibody (RM157) can be used for ELISA, multiplex-based assays, and Western blot (WB) applications.WARNING This product is not for human or veterinary use.
