Descripción

General description

A cell-permeable methylanthranilate analog that reversibly blocks vesicular traffic from the ER to the Golgi in mammalian cells (IC₅₀ = 20 µM in BSC1 cells) by inducing tubulation and collapsing of the Golgi membrane and re-directing the traffic back to the ER. Acts as a potent and selective modifier of Golgi ARF1 GTPase activity. Unlike another membrane traffic inhibitor, Brefeldin A (BFA) (Cat. No. 203729), the effects appear to be limited to the Golgi, as no effects are detected on endocytic organelles, such as endosomes and trans-Golgi network (TGN). The inhibitory mechanism and target(s) appear to be different from those of BFA, thus making it a valuable alternative that complements BFA in membrane trafficking studies.
