Reconstituted CMG Helicase Disassembly with Purified Proteins Requires Ubiquitylation, the Cdc48 ATPase, and Ufd1-Npl4
(A) GAL-ProteinA-TEV-DIA2 PSF2-5FLAG cells (YPM157) were processed as indicated. At the end of the reactions, the GINS component of the CMG helicase was isolated by immunoprecipitation of Sld5, in order to monitor the integrity of CMG.
(B) The samples described in (A) were resolved by SDS-PAGE, and the indicated proteins were analyzed by immunoblotting.
(C) Similar reactions were performed with the indicated factors.
