WebbSo, each of these different histone tail modifications are associated with a different function. We won't go through all of these, but methylation, which can occur as a single, which we tend to abbreviate as Me, can occur as a monomethylation, dimethylation, so two methyl groups, or trimethylation, three methyl groups.

WebbThe histone-fold domain has two defined functions: it heterodimerizes with a second histone – H3 with H4, H2A with H2B – and, once heterodimerized, it wraps DNA in the nucleosome. The basic N-terminal ‘tail’ domains lie outside the nucleosome and do not have any defined structure. lily joyceWebbThe biological function of histone methylation is best characterized in the context of histones H3 and H4 methylation.
