CBP-IDRs regulate acetylation and gene expression
Gelder et al. demonstrate that intrinsically disordered regions (IDRs) with divergent sequence properties maintain a functional balance between positive and negative regulation of CBP condensates. This intramolecular mechanism tunes CBP’s sensitivity to lysine acetylation; its disruption fundamentally alters chromatin binding, histone acetylation, and gene expression.
