Research Abstract

By using transient gene expression system in HEK293 cells, we identified Rab proteins that participate in cholesterol-dependent intracellular sorting of Niemann-Pick C1-Like1 (NPC1-L1) protein. We also studied intracellular localization of endogenous NPC1-L1 in HepG2 cells and found that localization of the endogenous NPC1-L1 was also regulated in a cholesterol-dependent manner.
