General description【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). Histones are modified post-translationally by the actions of enzymes in both the nucleus and cytoplasm. These modifications, which include acetylation, phosphorylation, methylation, and ubiquitin-ation, occur predominantly on the N-terminal and C-terminal tails that extend beyond the nucleosome core particle. Trimethylation of histone H4 on lys20 (H4-K20me3) selectively marks constitutive pericentromeric hetero-chromatin and imprinting control regions, while mono- and dimethylation are broadly distributed but principally enriched in euchromatin regions. Although the biological function of H4K20me remains poorly understood, studies suggest that H4-K20me2 is involved in the guidance of DNA repair proteins to DNA strand breaks, whereas H4K20me1 is associated with chromatin condensation processes. PR-Set7 (also known as SET8) specifically catalyzes monomethylation of H4K20me1. |
Specificity【特异性】 | Recognizes monomethyl-histone H4 (Lys20), Mr ~10kDa. The immunizing sequence is conserved from Tetrahymena to human, so broad species cross-reactivity is expected. |
Immunogen【免疫原】 | KLH-conjugated, synthetic peptide containing the sequence …HR[mmK]V…, in which mmK corresponds to monomethyl-lysine at residue 20 of human histone H4. |
Application【应用】 | Use Anti-monomethyl-Histone H4 (Lys20) Antibody, clone NL314 (rabbit monoclonal antibody) validated in WB, Mplex to detect monomethyl-Histone H4 (Lys20) also known as H4K20me1, Histone H4 (mono methyl K20). Immunoblot Analysis: A 1:4000 dilution of a previous lot detected methylated histone H3 in acid extracted proteins from HeLa cells. The antibody did not detect unmethylated recombinant Histone H3.
