White solid. 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. Purity: ≥95% by HPLC. RTECS GY8410000, CAS 20350-15-6.
