(A) SDS-PAGE/Coomassie Blue staining and immunoblot analyses of purified ySet1Cs reconstituted with baculovirus vectors in the absence of the indicated subunits. Complex loading was normalized to FLAG-Set1 (except lane 3, see below).
(B and C) Free histone H3 (B) and H2Bub-chromatin templates (C) were subjected to in vitro HMT assays with indicated ySet1Cs.
Note that because of inefficient complex formation in the absence of Swd1, a volume of the Swd1-deficient sample (lanes 3) equal to that of the intact complex sample (lanes 1) was used for SDS-PAGE and in vitro HMT assays.
