Function
MS3L1_HUMAN May be involved in chromatin remodeling and transcriptional regulation. May have a role in X inactivation. Component of the MSL complex which is responsible for the majority of histone H4 acetylation at 'Lys-16' which is implicated in the formation of higher-order chromatin structure. Specifically recognizes histone H4 monomethylated at 'Lys-20' (H4K20Me1) in a DNA-dependent manner and is proposed to be involved in chromosomal targeting of the MSL complex.[1] [2] [3] [4]

Publication Abstract from PubMed
MSL3 resides in the MSL (male-specific lethal) complex, which upregulates transcription by spreading the histone H4 Lys16 (H4K16) acetyl mark. We discovered a DNA-dependent interaction of MSL3 chromodomain with the H4K20 monomethyl mark. The structure of a ternary complex shows that the DNA minor groove accommodates the histone H4 tail, and monomethyllysine inserts in a four-residue aromatic cage in MSL3. H4K16 acetylation antagonizes MSL3 binding, suggesting that MSL function is regulated by a combination of post-translational modifications.
