MYST Histone Acetyltransferases (HAT), a diverse family of proteins responsible for a variety of functions in eukaryotes from yeast to humans. These particular histone acetyltransferases are part of the MYST family because of their structure which includes coenzyme A and .

Part of the Myst Family, this histone modifier adds and removes a variety of chemical moieties to histone residues. Such modifications on a single or on several neighboring nucleosomes combine to produce a specific effect on the local chromatin structure.

Function

Highly conserved in eukaryotes, their key roles in post-translation modification of histones. Profound effect on chromatin structure in eukaryotes. Composed of an Acetyl-CoA binding motif and a zinc finger.

Disease

residues of p53 acetylated by HATs may be located in variable sites, which leads to elevation of p53 DNA binding or loss of its transcriptional activity. It has been demonstrated that mutation of the C-terminal site of p53, where acetylation occurs, prompts comprehensively the loss of p53-dependent cyclin-dependent kinase inhibitor p21 transcription [49,50]. Acetylation of signal mediators may be prominent in subsequent stages in cancer progression.
