MYST family

The MYST family refers to a group of proteins that are part of a complex called the MYST family of histone acetyltransferases. These proteins play a crucial role in regulating gene expression by adding acetyl groups to histones, the proteins around which DNA is wrapped. This modification can loosen DNA-histone interactions, making genes more accessible for activation or repression. MYST proteins are involved in various vital processes such as cell cycle control, DNA repair, and development. They are found in many organisms, from yeast to humans, highlighting their essential role in maintaining normal cellular functions.
