| Description | |
|---|---|
| Overview | A cell-permeable methylanthranilate analog that reversibly inhibits vesicular traffic from ER to Golgi in mammalian cells (IC50 = 20 µM in BSC1 cells) by inducing tubulation and collapsing of the Golgi membrane and redirecting the traffic back to ER. Acts as a potent and selective modifier of Golgi ARF1 GTPase activity. Unlike another membrane traffic inhibitor Brefeldin A (BFA; Cat. No. 203729), its effect seems to be limited to Golgi, as no effect can be detected on endocytic organelles, such as endosomes and TGN (trans-Golgi network). Its inhibitory mechanism and target(s) appear to be quite different from those of BFA and thus serves as a valuable alternative that complements BFA in membrane traffic studies. |
