KAT7 or K (lysine) acetyltransferase 5 is a signaling protein that belongs to the MYST family of histone acetyl transferases (HATs) and was originally isolated as an HIV-1 TAT-interactive protein which play important roles in regulating chromatin remodeling, transcription and other nuclear processes by acetylating histone and non-histone proteins. KAT7 acts as a transcriptional inhibitor and inhibited AR-mediated transactivation of reporter constructs in CV-1 and PC-3 cells. KAT7 is part of a multisubunit complex that can acetylate histones H3 and H4.

The origin recognition complex (ORC) is an initiator protein for DNA replication, but also effects transcriptional silencing in Saccharomyces cerevisiae and heterochromatin function in Drosophila. It is not known, however, whether any of these functions of ORC is conserved in
