a histone acetyl transferase (HAT) of the MYST family. Originally isolated as an HIV-1 TAT-interactive protein. Plays an important role in regulating chromatin remodeling, transcription and other nuclear processes by acetylating nuclear proteins. Plays a role in DNA repair and apoptosis. Three splice variants have been described.. Note: This description may include information from UniProtKB.
Protein type: Acetyltransferase; EC 188.8.131.52; Nuclear receptor co-regulator; Nucleolus
Biological Process: DNA damage response, signal transduction by p53 class mediator resulting in transcription of p21 class mediator; DNA double-strand break processing; DNA replication; DNA synthesis during DNA repair; double-strand break repair; double-strand break repair via nonhomologous end joining; histone acetylation; negative regulation of interleukin-2 production; negative regulation of transcription from RNA polymerase II promoter; negative regulation of transcription, DNA-dependent; positive regulation of transcription from RNA polymerase II promoter; positive regulation of transcription, DNA-dependent; proteasomal ubiquitin-dependent protein catabolic process; response to ionizing radiation; strand displacement
