Notes: TIP60 is a member of the MYST family of lysine acetyl transferases. It has been shown to acetylate histones, p53, and the Ataxia Telangiectasia Mutant (ATM) protein kinase.{20520} As a component of the TIP60-p400 complex, TIP60 acetylates transcription repressors in order to inhibit gene transcription.{20521} In complexes without p400, TIP60 is part of a chromatin remodeling complex which plays an important role in double-stranded DNA break repair. Acetylation of histone γH2AX allows formation of the γH2AX repair foci, and acetylation of ATM is one of the early steps in double-stranded DNA break repair. Furthermore, TIP60 is bound by the cytoplasmic tail of β-amyloid precursor protein which drives gene transcription, apoptosis, and potentially a role in Alzheimer’s disease pathogenesis.{20522}
