Abstract:ESCO1 is an acetyltransferase enzyme that regulates chromosome organization and gene expression. It does this by modifying the Smc3 subunit of the Cohesin complex. Although ESCO1 is enriched at the base of chromatin loops in a Cohesin-dependent manner, precisely how it interacts with chromatin is unknown. Here we show that the basic and intrinsically disordered tail of ESCO1 binds DNA with very high affinity, likely through electrostatic interaction. We show that neutralization of positive residues in the N-ta… Show more
