[Bacterial toxins: useful for studying G-proteins implicated in the mechanism of exocytosis in neuroendocrine cells]

Autor: S, Gasman, S, Chasserot-Golaz, N, Vitale, M F, Bader

Publikováno v: Journal de la Societe de biologie. 193(6)

In neuroendocrine cells, regulated exocytosis is a multistep process that comprises the recruitment and priming of secretory granules, their docking to the exocytotic sites, and the subsequent fusion of granules with the plasma membrane leading to th

Identification of a plasma membrane-associated guanine nucleotide exchange factor for ARF6 in chromaffin cells. Possible role in the regulated exocytotic pathway

ADP-ribosylation factors (ARFs) constitute a family of structurally related proteins that forms a subset of the Ras superfamily of regulatory GTP-binding proteins. Like other GTPases, activation of ARFs is facilitated by specific guanine nucleotide e

Identification of a potential effector pathway for the trimeric Go protein associated with secretory granules. Go stimulates a granule-bound phosphatidylinositol 4-kinase by activating RhoA in chromaffin cells

Publikováno v: The Journal of biological chemistry. 273(27)

Besides having a role in signal transduction, heterotrimeric G proteins may be involved in membrane trafficking events. In chromaffin cells, Go is associated with secretory organelles, and its activation inhibits the ATP-dependent priming of exocytos

Regulated exocytosis in chromaffin cells. Translocation of ARF6 stimulates a plasma membrane-associated phospholipase D

Autor: A S, Caumont, M C, Galas, N, Vitale, D, Aunis, M F, Bader

Publikováno v: The Journal of biological chemistry. 273(3)

The ADP-ribosylation factor (ARF) GTP-binding proteins have been implicated in a wide range of vesicle transport and fusion steps along the secretory pathway. In chromaffin cells, ARF6 is specifically associated with the membrane of secretory chromaf

Structural analysis of junctions formed between lipid membranes and several annexins by cryo-electron microscopy

Autor: O, Lambert, V, Gerke, M F, Bader, F, Porte, A, Brisson

Publikováno v: Journal of molecular biology. 272(1)

The (annexin II-p11)2 tetramer has been proposed to participate in exocytosis and several other members of the annexin superfamily have been reported to aggregate liposomes in vitro. In this context, the Ca2+-dependent binding of several annexins to

Publikováno v: The Journal of biological chemistry. 272(5)

The ADP-ribosylation factor (ARF) GTP-binding proteins are believed to function as regulators of vesicular budding and fusion along the secretory pathway. To investigate the role of ARF in regulated exocytosis, we have examined its intracellular dist
