Conformational change and localization of calpactin I complex involved in exocytosis as revealed by quick-freeze, deep-etch electron microscopy and immunocytochemistry

Calpactin I complex, a calcium-dependent phospholipid-binding protein, promotes aggregation of chromaffin vesicles at physiological micromolar calcium ion levels. Calpactin I complex was found to be a globular molecule with a diameter of 10.7 +/- 1.7 (SD) nm on mica. When liposomes were aggregated b...
