Lysine Acetyltransferase p300 (EP300)

Target
EP300
Molecular classification
Enzyme, Histone modification, Transcription factor, Lysine Acetyltransferase
01

Overview

Lysine acetyltransferase p300 (EP300) is a transcriptional coactivator and histone acetyltransferase (HAT) that plays essential roles in chromatin remodeling and regulation of gene expression. It acetylates both histone and non-histone proteins, influencing various cellular processes including cell growth, differentiation, and development. Disruption or mutation of EP300 is associated with developmental disorders, neurological diseases, and cancer.
