Description General description Specifically and reversibly blocks translocation of proteins from the endoplasmic reticulum (ER) to the Golgi apparatus without affecting endocytosis or lysosome function. Inhibitor of HDL-mediated cholesterol efflux. Causes disassembly of the Golgi complex and ER swelling in a variety of mammalian cell lines at <40 ng/ml. Blocks binding of ADP-ribosylation factor to the Golgi and inhibits the GDP-GTP exchange. Inhibits the activity of BIG1 and BIG2, the guanine-nucleotide exchange proteins for ADP-ribosylation factors. Also available as a 25 mM solution in DMSO (Cat. No. 500583).
