Tomosyn is expressed in β-cells and negatively regulates insulin exocytosis

- diabetesjournals.org
W Zhang, L Lilja, SA Mandic, J Gromada, K … - Diabetes, 2006 - Am Diabetes Assoc
Tomosyn, a syntaxin-binding protein, is capable of dissociating mammalian
homolog of the Caenorhabditis elegans unc-18 gene from syntaxin and is involved
in the regulation of exocytosis. We have investigated the expression, ...

PKA-catalyzed phosphorylation of tomosyn and its implication in Ca2+-dependent exocytosis …

- rupress.org
T Baba, T Sakisaka, S Mochida, Y Takai - Journal of Cell Biology, 2005 - jcb.rupress.org
Neurotransmitter is released from nerve terminals by Ca 2+ -dependent exocytosis
through many steps. SNARE proteins are key components at the priming and fusion
steps, and the priming step is modulated by cAMP-dependent protein kinase ...

Tomosyn-1 is involved in a post-docking event required for pancreatic {beta}-cell exocytosis

- biologists.org
S Cheviet, P Bezzi, R Ivarsson, E Renstrom, D … - Journal of Cell Science, 2006 - jcs.biologists.org
Although the assembly of a ternary complex between the SNARE proteins
syntaxin-1, SNAP25 and VAMP2 is known to be crucial for insulin exocytosis, the
mechanisms controlling this key event are poorly understood. We found that ...

New insights into the molecular mechanisms of priming of insulin exocytosis


EP Kwan, HY Gaisano - Diabetes Obes Metab, 2007 - interscience.wiley.com
Exocytosis of insulin vesicles in the pancreatic β-cell involves a sequence of
regulated events, whose normal function and efficient adaptation to increased
demand are essential for the maintenance of glucose homeostasis. These ...

Using microarrays to facilitate positional cloning: identification of tomosyn as an inhibitor of …


M Dybbs, J Ngai, JM Kaplan - PLoS Genet, 2005 - genetics.plosjournals.org
Forward genetic screens have been used as a powerful strategy to dissect complex
biological pathways in many model systems. A significant limitation of this
approach has been the time-consuming and costly process of positional ...

Receptor-mediated regulation of tomosyn-syntaxin 1A interactions in bovine adrenal …

- jbc.org
SE Gladycheva, AD Lam, J Liu, M D'Andrea- … - Journal of Biological Chemistry, 2007 - ASBMB
Tomosyn, a soluble R-SNARE protein identified as a binding partner of the
Q-SNARE syntaxin 1A, is thought to be critical in setting the level of
fusion-competent SNARE complexes for neurosecretion. To date, there has ...

Tomosyn negatively regulates both synaptic transmitter and neuropeptide release at the C. …

- physoc.org
EO Gracheva, AO Burdina, D Touroutine, M … - The Journal of Physiology, 2007 - Physiological Soc
The SNARE proteins, syntaxin, SNAP-25 and synaptobrevin form a tertiary complex
essential for vesicle fusion. Proteins that influence SNARE complex assembly are
therefore likely to be important regulators of fusion events. In this study ...

Two distinct genes drive expression of seven tomosyn isoforms in the mammalian brain, …


AJA Groffen, L Jacobsen, D Schut, M Verhage - Journal of neurochemistry, 2005 - interscience.wiley.com
Tomosyn was previously identified as a syntaxin-binding protein that inhibits
soluble NSF (n-ethylmaleimide-sensitive fusion protein) attachment protein
receptor (SNARE)-mediated secretion. We set out to investigate the ...

Tomosyn inhibits synaptic vesicle priming in Caenorhabditis elegans


EO Gracheva, AO Burdina, AM Holgado, M … - PLoS Biol, 2006 - biology.plosjournals.org
Caenorhabditis elegans TOM-1 is orthologous to vertebrate tomosyn, a cytosolic
syntaxin-binding protein implicated in the modulation of both constitutive and
regulated exocytosis. To investigate how TOM-1 regulates exocytosis of ...

O Yizhar, U Matti, R Melamed, Y Hagalili, D … - Proceedings of the National Academy of Sciences of …, 2004 - National Acad Sciences
Neurotransmitter release is a multistep process that is coordinated by a large
number of synaptic proteins and depends on proper protein–protein
interactions. Using morphological, capacitance, and amperometric ...
