Proteolytic processing of overexpressed eB1ΔE derivatives. Cell-free assay using COS membranes expressing eB1ΔEΔtag (left), eB1ΔEΔtagΔYKV (middle) and eB1ΔEΔ34 (right). Antibodies used were indicated below the panels. All derivatives (arrowheads) were cleaved to generate ICD-like peptides (asterisks) by γ-secretase activity.
