FIGURE 1: GFP-Opi1p re-localises to lipid droplets in cells lacking Scs3p. (A) GFP-Opi1p was expressed in wild-type cells (left) and scs3∆ cells (right) that were grown without inositol. In wild-type cells, GFP-Opi1p localises most prominently to the nuclear envelope, and also to the cortical ER that forms patches adjacent to the cell periphery [30]. In scs3∆ cells, GFP-Opi1p is only faintly on the nuclear envelope, and mostly in puncta. Arrowheads indicate these puncta and the corresponding positions in the accompanying transmission image. (B) scs3∆ cells expressing GFP-Opi1p as in A (1st panel), and co-expressing RFP-Erg6p, a lipid droplet marker (2nd panel), with pseudo-coloured green and red merge (panel 3, superposition = yellow) and transmission image (panel 4).
