Endosidin-2
Based on 3 publication(s) in Google Scholar
Endosidin-2 (ES2) is a selective inhibitor targeting the conserved exosome subunit EXO70. Endosidin-2 binds to the C-terminal domain of EXO70, inhibiting exocytosis and endosomal recycling, while promoting vacuolar trafficking in plant cells. Endosidin-2 interferes with the EXO70-mediated vesicle-to-plasma membrane anchoring process, leading to abnormal aggregation of auxin transporters (such as PIN2) in the cytoplasm and redirected to vacuolar degradation, while causing abnormal Golgi structure (such as cup-shaped or ring-shaped vesicles cisternae formation). Endosidin-2 can inhibit exocytosis in plant and mammalian cells and is mainly used to study the dynamic regulation of membrane trafficking (such as polar growth, vesicle sorting).

Biological Activity
1. Arabidopsis root epidermal cell PIN2 protein localization experiment: Endosidin-2 (40 μM; 2 h) significantly reduced the PIN2-GFP fluorescence intensity on the plasma membrane, induced PIN2 to accumulate in the ARA7/RabF2b-marked late endosome/pre-vacuolar compartment, inhibited exocytosis and enhanced vacuolar transport.[1].
2. Arabidopsis root epidermal cell multi-protein tracing experiment: Endosidin-2 (50 μM; 1.5-3 h) can cause PIN2, PIN3, and PIN4 to form abnormal aggregates (ES2As) in the cytoplasm, accelerate PIN2 endocytosis and redirect it to the vacuole, without affecting the localization of SYT1 protein, causing the Golgi apparatus to appear cup-shaped or ring-shaped cisternae and other structural abnormalities[1][2].
