Abstract

Two dynamin II - specific antibodies were used to detect dynamin II attached to highly purified Golgi membranes of HepG2 cells. Within the Golgi apparatus dynamin II is predominantly localized to the trans-Golgi network, as shown by immunoelectron microscopy. Increased binding of dynamin II to the trans-Golgi network in the presence of GTP-gamma-S and a reduced binding upon stimulation of secretion by phorbolester indicates that dynamin II may have a function in post-Golgi vesicle transport.
