(a) Diagrams representing GFP-tagged WT HACE1 and mutant HACE1 (HACE1Δ HECT and HACE1Δ ANK) constructs transiently transfected into Hace1−/− MEF for protein aggregate clearance assay. (b–d) Representative confocal micrographs of (b) WT, (c) ΔHECT and (d) ΔANK MEF subjected to protein aggregate clearance assay by pulsing with puromycin for 4 h to induce protein aggregate formation followed by an 8-h chase to monitor for aggregate clearance. Vehicle-treated MEFs were used as control. Scale bars, 10 μm.
