PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	two chromo domain : one at the N, the other at the C terminus
	a canonical methyllysine binding pocket made up of residues Tyr-31, Phe-56, Trp-59, and Trp-63
	a highly conserved N-terminal chromo-barrel domain (CBD) (residues 2–91
	a conserved C-terminal MRG domain (residues 196–512) , responsible for interactions with MSL1, but does not interact directly with MYST1

HOMOLOGY

interspecies

homolog to Drosophila male-specific lethal 1

Homologene

FAMILY

CATEGORY

transcription factor

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,nucleus

basic FUNCTION	role in chromatin remodeling and transcription regulation
	essential for cell viability
	plays an important role in targeting the male specific lethal complex to chromatin in both humans and flies by binding to H4K20Me(1)
	may help to target the MSL complex to specific chromatin regions at least in part by binding to H4K20Me1

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

resides in the MSL (male-specific lethal) complex, which upregulates transcription by spreading the histone H4 Lys16 (H4K16) acetyl mark

INTERACTION

DNA

RNA

small molecule

protein	MSL1 interacts with MSL3 as an extended chain forming an extensive hydrophobic interface
	interact directly with MYST1 via its conserved C-terminal MRG domain

cell & other

REGULATION

Other

MSL function is regulated by a combination of post-translational modifications
