NCIt definition : A post-translationally modified form of histone H3 where the lysine residue at position
4 is dimethylated. This modification may be a marker for transcriptionally active
genes.;
NCIt note : Even though the literature refers to lysine 4 methylation/other modification or amino
acid variation/mutation, RefSeq indicates that the lysine is located at amino acid
position 5 in histone H3. (see also https://link.springer.com/article/10.1007/s00401-018-1867-2);
