KAT5 Antibody – Rabbit Polyclonal

The protein encoded by this gene belongs to the MYST family of histone acetyl transferases (HATs) and was originally isolated as an HIV-1 TAT-interactive protein. HATs play important roles in regulating chromatin remodeling, transcription and other nuclear processes by acetylating histone and nonhistone proteins. This protein is a histone acetylase that has a role in DNA repair and apoptosis and is thought to play an important role in signal transduction. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008]

Tip60: 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.
