UniProtKB description: Component of the male-specific lethal (MSL) histone acetyltransferase complex, a multiprotein complex essential for elevating transcription of the single X chromosome in the male (X chromosome dosage compensation) (PubMed:7588059, PubMed:7781064, PubMed:7796814, PubMed:27580037, PubMed:31320325). Within the MSL complex, Msl-2 constitutes the main determinant of X chromosome-selective binding: recognizes X-specific DNA motifs, named PionX sites, which are characterized by sequence features and distinct DNA conformation (base roll) (PubMed:27580037, PubMed:31320325, PubMed:37602401). Msl-2 is required for translation and/or stability of msl-1 in males (PubMed:7588059, PubMed:7781064, PubMed:7796814). In complex with msl-1, acts as an E3 ubiquitin ligase that promotes ubiquitination of histone H2B (PubMed:21726816).
