E1A Binding Protein p300 Bromodomain (p300 Bromodomain)

Target
p300 Bromodomain
Molecular classification
Bromodomain, Epigenetic reader, Histone acetyltransferase (HAT) domain
01

Overview

The p300 bromodomain is a protein module within the E1A binding protein p300 (EP300) that recognizes and binds to acetylated lysine residues on histones. This interaction facilitates the recruitment of other regulatory proteins and modulates gene transcription by influencing chromatin structure and accessibility. As a key epigenetic reader, the p300 bromodomain is considered a promising therapeutic target, particularly in cancer, where its dysregulation contributes to aberrant gene expression patterns.
