GCN5

GCN5 is an enzyme called a histone acetyltransferase that plays a key role in gene regulation. It modifies proteins called histones, around which DNA is wrapped, by attaching acetyl groups. This chemical change typically relaxes the DNA structure, making genes more accessible for activation. GCN5 is involved in important processes like controlling cell growth, development, and response to signals. It functions within larger complexes to coordinate gene expression and can influence how cells behave, grow, and differentiate—making it essential for normal cellular functions and development.
