Colocalization studies. PfSCD-GFP was colocalized with different compartment markers: ER (PfBip, PfDSI), cis-Golgi (PfERD2), mitochondria (MitoTracker Red), and apicoplast (PfACP PFB0385w). PfSCD-GFP colocalized mostly with PfBiP and PfDSI (disulfide isomerase), two soluble ER markers, therefore confirming the ER localization of PfSCD-GFP. In contrast, the GFP-tagged PfSCD protein did not colocalize with ERD2, a known marker of the cis-Golgi.
