SNARE-dependent signaling at the Drosophila wing marginB A Stewart
Program in Developmental Biology, The Hospital for Sick Children Research Institute, Toronto, Ontario, M5G 1X8, Canada
Dev Biol 234:13-23. 2001..We conclude that SNARE-mediated membrane trafficking is an important component of wing margin development and that dosage-sensitive developmental pathways will act as a sensitive reporter of partial membrane-trafficking disruption...
Analysis of the mutant Drosophila N-ethylmaleimide sensitive fusion-1 protein in comatose reveals molecular correlates of the behavioural paralysisM Mohtashami
Programme in Cell Biology, Developmental Biology, Hospital for Sick Children, Toronto, Ontario, Canada
J Neurochem 77:1407-17. 2001..Together, these results suggest that dNSF-1 is required for adult neuronal function, but that in the larval nmj function may be maintained by other isoforms...
SNARE proteins contribute to calcium cooperativity of synaptic transmissionB A Stewart
Department of Molecular and Medical Genetics, Zoology, and Biochemistry, University of Toronto, 555 University Avenue, Toronto, ON, Canada
Proc Natl Acad Sci U S A 97:13955-60. 2000..Surprisingly, we found that reducing these SNARE proteins also reduced Ca(2+) cooperativity. Thus, SNARE proteins are important for determining the cooperative relationship between calcium and synaptic transmission...
Improved stability of Drosophila larval neuromuscular preparations in haemolymph-like physiological solutionsB A Stewart
Department of Physiology, University of Toronto, Ontario, Canada
J Comp Physiol A 175:179-91. 1994..Thus, haemolymph-like solutions allow for prolonged, stable recording of synaptic transmission...
Drosophila Amphiphysin is a post-synaptic protein required for normal locomotion but not endocytosisP A Leventis
Department of Zoology, University of Toronto, Toronto, Canada
Traffic 2:839-50. 2001..However, Drosophila Amphiphysin function is required in both larvae and adults for normal locomotion...
Homeostasis of synaptic transmission in Drosophila with genetically altered nerve terminal morphologyB A Stewart
Department of Physiology, University of Toronto, Ontario, Canada
J Neurosci 16:3877-86. 1996..These results show that morphological parameters of transmitting nerve terminals can be adjusted to functionally compensate for genetic perturbations, thereby maintaining optimal synaptic transmission...
Two distinct effects on neurotransmission in a temperature-sensitive SNAP-25 mutantS S Rao
Department of Neurobiology and Behavior, Cornell University, Ithaca, NY 14853, USA
EMBO J 20:6761-71. 2001..Our data suggest that at 22 degrees C the mutation causes the SNARE complex to be more fusion competent but, at 37 degrees C the same mutation leads to SNARE multimer instability and fusion incompetence...
Distinct requirements for evoked and spontaneous release of neurotransmitter are revealed by mutations in the Drosophila gene neuronal-synaptobrevinD L Deitcher
Department of Molecular and Cellular Physiology, Beckman Center, Stanford University Medical Center, Stanford, California 94305, USA
J Neurosci 18:2028-39. 1998..Thus, at least a portion of the spontaneous "minis" that are seen at the synapse can be generated by a protein complex that is distinct from that required for an evoked synaptic response...
