JADE1 selectively binds to H3/H4 over H2A/H2B and the nucleosome core particle.
A, MBP-JADE1 pulldowns of HBO1 HAT and (H3/H4 or H2A/H2B) in the presence or absence of each other, with results resolved on SDS-PAGE. MW Std., molecular weight standard. B, MBP-JADE1 pulldowns of HBO1 HAT and H3/H4, H2A/H2B and mixtures of the two with results resolved on SDS-PAGE. C, MBP-JADE1 pulldowns of H3/H4 or nucleosome core particles with results resolved on SDS-PAGE. D, activity comparison of HBO1 HAT and HBO1 full-length in the presence and absence of a saturating concentration of JADE1(1–188) as either H3H4 complex or nucleosome core particles as the substrate. The activity of these proteins on various substrates was compared using radioactive counts.
