title: Getting a "Hold" on NPC2.
abstract: Lipoprotein cholesterol is mobilized from lysosomes by actions of the NPC1 and NPC2 proteins. In this issue of Cell Metabolism, Harrison et al. report on identification of an NPC2-interacting protein, the Nogo-B receptor, that regulates NPC2 protein levels. NPC2 stabilization may represent a novel mechanism through which cells respond to endocytosed cholesterol.
