NCIt definition : A form of histone H3 where the lysine residue at position 4 has been post-translationally
modified with a single methyl group. 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);
