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.
