NuA4

NuA4 is a complex of proteins in cells that plays a crucial role in regulating gene activity. It acts as a histone acetyltransferase, meaning it adds chemical groups called acetyl groups to histone proteins around which DNA is wrapped. This modification relaxes the DNA structure, making genes more accessible for activation. Essentially, NuA4 helps control when and how genes are turned on or off, influencing processes like cell growth and development. It is particularly important in processes like gene expression and DNA repair, maintaining proper cellular function.
