Proteomic profiling of the prechylomicron transport vesicle involved in the assembly and secretion of apoB‐48‐containing chylomicrons in the intestinal enterocytes

Intracellular assembly of chylomicrons (CM) occurs in intestinal enterocytes through a series of complex vesicular interactions. CM are transported from the ER to the Golgi using a specialized vesicular compartment called the prechylomicron transport vesicle (PCTV). In this study, PCTVs were isolated from the enteric ER of the Syrian Golden hamster, and characterized using 2-DE and MS. Proteomic profiles of PCTV-associated proteins were …
