L3MBTL1 recognition of mono- and dimethylated histones.

PubMed Abstract: Crystal structures of the L3MBTL1 MBT repeats in complex with histone H4 peptides dimethylated on Lys20 (H4K20me2) show that only the second of the three MBT repeats can bind mono- and dimethylated histone peptides. Its binding pocket has similarities to that of 53BP1 and is able to recognize the degree of histone lysine methylation. An unexpected mode of peptide-mediated dimerization suggests a possible mechanism for chromatin compaction by L3MBTL1.
