A. GFP-Snc1-PEM protein accumulates in atg1Δ, atg8Δ, and atg11Δ mutant cells. Lysates were prepared from wild type (WT), ypt1-1 (for comparison), atg1Δ, atg8Δ, and atg11Δ mutant cells transformed with a 2μ plasmid expressing GFP-Snc1-PEM from the TPI promoter. The level of GFP-Snc1-PEM was determined using immunoblot analysis with anti-GFP antibodies. The bands were quantified and increase in the protein level in mutant versus the WT cells is shown under the blot and adjusted to the G6PDH loading control.
