Figure 4. Multiple copies of MEX67 or DBP5 rescue impaired RLS in sus1Δ cells. (A) Strategy used to identify specific genes that suppress sus1Δ defects. sus1Δ cells containing pRS316-SUS1 were transformed with the indicated pGP564 (LEU2)-based plasmids, including NPC-related genes. Cells were streaked on SC-Trp-His-Leu supplemented with 5-FOA twice to evict pRS316-SUS1. (B) Growth analysis of WT or sus1Δ strains transformed with the indicated plasmids, as described in
