Figure 5: Selective mitophagy of matrix proteins depends on mitochondrial dynamics.

From: Involvement of mitochondrial dynamics in the segregation of mitochondrial matrix proteins during stationary phase mitophagy

Figure 5

WT (a), dnm1Δ (b) and atg1Δ cells (c) and atg32Δ cells (d) expressing chromosomally tagged GFP chimeras of Aco2, Idh2, Idp1 and Hsp78 were incubated in SL medium for 7 days, and 10 OD600 units were sampled at day 1 and day 7 and processed for immunoblotting with anti-GFP antibodies as described in the Methods section. Positive control used in c and d was from dnm1Δ cells expressing Idp1-GFP from a plasmid at 4-day incubation (Fig. 1b, lane 4). Release of free GFP in WT cells is reproducibly variable between these reporters, and varies between 0 (Idh2) and 60% (Aco2). (e) Densitometric quantification of the release of free GFP (as % of total signal) in four independent experiments, comparing the results between WT and dnm1Δ cells. Bars denote s.d. (n=4).
