label_lc: atp-dependent h2az histone chaperone activity
description: "A histone chaperone that mediates the exchange of histone H2A-H2B dimer and histone H2AZ-H2B dimers in a nucleosome, driven by ATP hydrolysis. Some chaperones insert H2AZ-H2B dimers and remove H2A-H2B, while others do the opposite."
