This domain is found in Male-specific lethal-3 (MSL3) and other related proteins such as MRG15 transcription factor. MSL3 resides in the MSL (male-specific lethal) complex, which upregulates transcription by spreading the histone H4 Lys16 acetyl mark. The MSL3 chromo domain implicated in chromatin targeting and its deletion leads to the disruption of MSL targeting. The MRG15 chromo domain is involved in chromatin remodelling and transcription regulation. This domain consists of a SH3-like beta-barrel and a long alpha-helix.	Domain
