Intracellular trafficking of CT/GM1. From the early endosome, CT/GM1 complexes take at least two pathways. First is the pathway back to the PM. Second is the pathway via the Golgi apparatus to the ER. Our findings suggest that transport back to the PM depends on the function of NPC1, whereas transport to the Golgi apparatus/ER does not.
