The gene MSL1 (male specific lethal 1 homolog) encodes a histone acetyl transferase-associated protein that spans a length of 614 amino acid residues. It does not contain any globular domains.
Biochem/physiol Actions
The gene MSL1 (male specific lethal 1 homolog) encodes a protein associated with mammalian MOF (male-absent-on-the-first)-MSL (male-specific-lethal) complex that is also referred to as the ‘dosage compensation complex′ (DCC). This complex is involved in the equalization of X-chromosomal genes expression between males and females. It is found to form a complex with Nupr1 (nuclear protein 1) in the nucleus in response to DNA-damage and may be involved in DNA repair activity. MSL1 protein is found to regulate acetylation of global histone H4 via its interaction with KAT8 (lysine acetyltransferase 8).

The stress protein Nupr1 is a highly basic, multifunctional, intrinsically disordered protein (IDP). MSL1 is a histone acetyl transferase-associated protein, known to intervene in the dosage compensation complex (DCC). In this work, we show that both Nupr1 and MSL1 proteins

MSL1 protein regulates global histone H4 acetylation at residue K16 in stem and cancer cells, through interaction with KAT8. The functional significance of mammalian MSL1 isoforms, involved in various protein interactions, is poorly understood. We report the identification of a
