Bromodomain-containing protein Second Bromodomain (BD2)

Target
BD2
Molecular classification
Protein Domain, Bromodomain, Epigenetic reader
01

Overview

The second bromodomain (BD2) found in BET family proteins (BRD2, BRD3, BRD4, and BRDT). BD2 is an epigenetic reader that recognizes acetylated lysine residues on histone tails, thereby regulating gene expression. Inhibition of BD2 is being explored as a therapeutic strategy in cancer and inflammatory diseases.
