Thermodynamic characterization of the binding interaction between the histone demethylase LSD1/KDM1 and CoREST.

ABSTRACT: Flavin-dependent histone demethylases catalyze the posttranslational oxidative demethylation of mono- and dimethylated lysine residues, producing formaldehyde and hydrogen peroxide in addition to the corresponding demethylated protein. In vivo, histone demethylase LSD1 (KDM1; BCH110) is a component of the multiprotein complex that includes histone deacetylases (HDAC 1 and 2) and the scaffolding protein CoREST. Although little is known about the affinities of or the structural basis for the interaction between CoREST and HDACs, the structure of CoREST(286-482) bound to an α-helical coiled-coil tower domain within LSD1 has recently been reported. Given the significance of CoREST in directing demethylation to specific nucleosomal substrates, insight into the molecular basis of the interaction
