Secretory vesicle budding from the trans-Golgi network is mediated by phosphatidic acid levels.
Phospholipid metabolism plays a central role in regulating vesicular traffic in the secretory pathway. In mammalian cells, activation of a Golgi-associated phospholipase D activity by ADP-ribosylation factor results in hydrolysis of phosphatidylcholine to phosphatidic acid (PA). This reaction has been proposed to stimulate nascent secretory vesicle budding from the trans-Golgi network. It is un...
متن کاملSyntaxin 6 functions in trans-Golgi network vesicle trafficking.
The specific transfer of vesicles between organelles is critical in generating and maintaining the organization of membrane compartments within cells. Syntaxin 6 is a recently discovered member of the syntaxin family, whose constituents are required components of several vesicle trafficking pathways. To better understand the function of syntaxin 6, we generated a panel of monoclonal antibodies ...
متن کاملVesicle-associated membrane protein 4 is implicated in trans-Golgi network vesicle trafficking.
The trans-Golgi network (TGN) plays a pivotal role in directing proteins in the secretory pathway to the appropriate cellular destination. VAMP4, a recently discovered member of the vesicle-associated membrane protein (VAMP) family of trafficking proteins, has been suggested to play a role in mediating TGN trafficking. To better understand the function of VAMP4, we examined its precise subcellu...
متن کاملDistinct coated vesicles labeled for p 200 bud from trans - Golgi network membranes ( vesicle trafficking / Golgi / vesicle coat ) NAVNEET NARULA
Golgi-associated cytoplasmic proteins, such as the coatomer protein complex, are required for vesicle budding and trafficking. We have previously described a cytoplasmic phosphoprotein, p200, which binds dynamically and specifically to Golgi membranes. The p200 protein is dissociated from Golgi membranes in the presence ofbrefeldin A and it is induced to bind to Golgi membranes by activation of...
متن کاملGolgi Cisternal Unstacking Stimulates COPI Vesicle Budding and Protein Transport
The Golgi apparatus in mammalian cells is composed of flattened cisternae that are densely packed to form stacks. We have used the Golgi stacking protein GRASP65 as a tool to modify the stacking state of Golgi cisternae. We established an assay to measure protein transport to the cell surface in post-mitotic cells in which the Golgi was unstacked. Cells with an unstacked Golgi showed a higher t...
