Intracellular distribution of ECE-2. SH-SY5Y-APP cells transiently transfected with ECE-2 (variant 2) were co-stained with antibodies against ECE-2 and markers of various intracellular compartments. Co-localization of ECE-2 with rab5, rab7, and lamp-1, markers of early endosome, late endosome, and lysosome, respectively, demonstrated that ECE-2 is mostly located in the endosomal/lysosomal pathway. In contrast, ECE-2 did not co-localize with TGN38, a marker of the trans-Golgi network, suggesting that ECE-2 does not conduct its activity within the secretory pathway.
