Histone acetyltransferases (HATs) enzymes regulate the acetylation of histones and nonhistone proteins.
Histone proteins are found in association with multiple DNA regions throughout the chromosomes, whereas other nonhistone proteins (called "transcription factors") are characterized by DNA-binding segments that enable them to attach to target nucleotide sequences and regulate the transcription of specific genes.
