In humans, PR-DUB, composed of BAP1 and ASXL1, functions as a monomeric complex, while the homolog Calypso/Asx forms a bidentate dimer (Calypso: Asx) with an unclear chromatin engagement mechanism. Here, we present its cryo-EM structure bound to a nucleosome, revealing the molecular basis of interaction. Surprisingly, only one Calypso/Asx unit engages the nucleosome in a conformation similar to human BAP1/ASXL1, while the second remains disengaged. Structural and biochemical analysis of the positively charged Calypso C terminus suggests a "spreading" potential of the bidentate complex along chromatin, which was validated using nucleosome arrays. These findings support a model in which the bidentate Calypso/Asx complex enables processive deubiquitination along chromatin via alternating or cooperative engagement. | |||||||||||||||||||||||||||
