UniProtKB description:  Histone acetyltransferase that plays a direct role in the specific histone acetylation associated with dosage compensation as part of the male-specific lethal (MSL) complex (PubMed:9155031, PubMed:16543150, PubMed:34133927). Dosage compensation ensures that males with a single X chromosome have the same amount of most X-linked gene products as females with two X chromosomes (PubMed:9155031). May be directly involved in the acetylation of histone 4 at 'Lys-16' on the X chromosome of males where it is recruited by the MSL complex (PubMed:11258702). As part of the nonspecific lethal (NLS) complex may associate with promoters of X chromosomal as well as autosomal genes and positively regulate their transcription through chromatin modification (PubMed:20620954).
