Figure 4. APT-mT interactomes and localization.
(A) Volcano plot of APT1-mT prey relative to parental prey based on LFQ intensities.
(B) Volcano plot of APT2-mT prey relative to parental prey based on LFQ intensities.
Red proteins in (A) and (B) have increased labeling by the APT-mT construct based on a Perseus analysis with S0 = 2. Cyan- or blue-labeled proteins in (A) and (B) are proteins of interest for future study.
(C) Principal-component analysis of LFQ intensities from mT MS data.
(D) Confocal microscopy of mT-expressing HepG2 cells. V5: tag for mT constructs. Tomm20: mitochondrial marker. Hoechst: nuclear marker. Scale bars: 10 μm (top) and 2 μm (bottom).
