ALCAT1 hampers SC formation under stimulated OXPHOS conditions. (a) Fluorescence lifetime images of sEcGFP at subunit CoxVIIIa. This construct is buried in an existing respiratory supercomplex and has a reduced fluorescence lifetime τ. As a control, subunit CoxIV was labeled with sEcGFP, which does not respond to SC formation by decreased lifetime [28]. Cells were transfected with ALCAT1-mCherry (tr. ALCAT1) and grown in a glucose (5.6 mM) or galactose (10 mM) medium for 48 h. (b) Average fluorescence lifetimes τamp of CoxVIIIa-sEcGFP under different respiratory conditions +/- ALCAT1-mCherry overexpression. (c) Average fluorescence lifetimes τamp of CoxIV-sEcGFP under different respiratory conditions±ALCAT1-mCherry overexpression. N = 2 replicates. Data was analyzed by One-Way ANOVA with post hoc Scheffe test. Scale bars: 20 μM (a).
