Histone acetyltransferases (HATs)
Histone acetyltransferases (HATs) are enzymes that play a crucial role in regulating gene expression in our cells. They add acetyl groups to histones, which are proteins that package DNA. This modification alters how tightly the DNA is wrapped around histones, making it more accessible for transcription, the process that turns DNA into RNA and ultimately proteins. When HATs are active, they usually promote gene activation, influencing processes like cell growth and differentiation. In essence, HATs are key players in determining which genes are turned on or off, impacting many biological functions and pathways.

Histone acetyltransferases (HATs) are enzymes that play a critical role in gene regulation. They add acetyl groups to histone proteins, which are essential for packaging DNA in the cell. This process makes DNA more accessible for transcription, the first step in gene expression. When HATs are active, genes can be turned on more easily, promoting cellular functions. HATs are important for various biological processes, including development, response to signals, and maintaining cellular health. Dysregulation of HAT activity can be linked to diseases, including cancer, making them significant in biomedical research.
