Histone acetyltransferase KAT5 is an enzyme that in humans is encoded by the KAT5 gene.[1][2]

Function[edit]

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.[2]

Interactions[edit]

HTATIP has been shown to interact with HDAC7A,[3] FANCD2,[4] CREB1,[5] ETV6,[6] Mdm2,[7] Myc,[8] BCL3,[9] Androgen receptor,[10] Endothelin receptor type A[11] and PLA2G4A.[12]
