== Function == | |||
[https://www.uniprot.org/uniprot/MSL3_DROME MSL3_DROME] The MSL proteins are essential for elevating transcription of the single X chromosome in the male (X chromosome dosage compensation). Mle, msl-1 and msl-3 are colocalized on the X chromosome. Each of the MSL proteins requires all the other MSLs for wild-type X-chromosome binding.<ref>PMID:7768187</ref> | |||

== 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. | |||
