Biochem/physiol Actions

Endosidin9 (ES9) is a potent inhibitor of clathrin-mediated endocytosis (CME) in Arabidopsis thaliana, HeLa cells and Drosophila neurons. It binds directly to N-terminal domain of clathrin heavy chain. Also, Endosidin9 is a mitochondrial uncoupler that displays protonophore activities leading to cytoplasm acidification.

ATP production requires the establishment of an electrochemical proton gradient across the inner mitochondrial membrane. Mitochondrial uncouplers dissipate this proton gradient and disrupt numerous cellular processes, including vesicular trafficking, mainly through energy depletion. Here we show that Endosidin9 (ES9), a

Clathrin-mediated endocytosis (CME) is a highly conserved and essential cellular process in eukaryotic cells, but its dynamic and vital nature makes it challenging to study using classical genetics tools. In contrast, although small molecules can acutely and reversibly perturb CME
