背景信息

The TriMethyl-Histone H3 (Lys79) antibody is a key tool for studying post-translational modifications of histone H3. specifically recognizing trimethylation at lysine 79 (H3K79me3). This epigenetic mark is associated with transcriptionally active chromatin and plays roles in gene regulation, DNA repair, and cell cycle control. H3K79 methylation occurs within the globular core of the histone, a unique location compared to other modifications in the N-terminal tail. The modification is catalyzed by the methyltransferase DOT1L, which is the only known enzyme responsible for this mark in mammals.

H3K79me3 is enriched in gene bodies of actively transcribed genes, suggesting its involvement in transcriptional elongation. It also participates in DNA damage response pathways and maintains genomic stability. Dysregulation of H3K79 methylation has been linked to cancers, particularly leukemias with MLL gene rearrangements, where aberrant DOT1L activity drives oncogenic gene expression.

Researchers use this antibody in techniques like chromatin immunoprecipitation (ChIP), immunofluorescence, and Western blot to map H3K79me3 distribution, investigate its functional roles, and explore its therapeutic implications. Its specificity is critical for distinguishing trimethylation from mono- or dimethylated states, which may have distinct biological outcomes. Proper validation, including knockout cell controls, is essential due to potential cross-reactivity with other histone modifications.
