一般描述
Histones are highly conserved proteins that serve as the structural scaffold for the organization of nuclear DNA into chromatin. The four core histones, H2A, H2B, H3, and H4, assemble into an octamer (2 molecules of each). Subsequently, 146 base pairs of DNA are wrapped around the octamer, forming a nucleosome. Histones are modified post-translationally; and these modifications regulate DNA transcription, repair, recombination, and replication. The most commonly studied modifications are acetylation, phosphorylation, methylation, and ubiquitination. The modifications occur predominantly on the N-terminal and C-terminal tails that extend beyond the nucleosome core particle. Trimethylation of histone H3 (Lys4) is is found at the 5′ end of active genes and contributes to transcriptional activation by recruiting chromatin-remodelling enzymes. Accordingly, the inactive X chromosome is largely devoid of this mark.
特异性
This antibody specifically recognizes Histone H3 trimethylated at Lys4. The antibody binding specificity allows for modifications of Lys91.
Broad species cross-reactivity is expected, based on sequence homology.
免疫原
