Tomo-1 overexpression increased dendritic spine density, whereas Tomo-1 knockdown (KD) decreased spine density.
Title: The ubiquitin-proteasome system functionally links neuronal Tomosyn-1 to dendritic morphology.
We suggest that tomosyn uses its CTD to arrest SNARE-dependent fusion reactions, whereas its NTD is required for the recruitment of tomosyn to vesicle fusion sites through syntaxin interaction.
Title: The N- and C-terminal domains of tomosyn play distinct roles in soluble N-ethylmaleimide-sensitive factor attachment protein receptor binding and fusion regulation.
Unstructured loops in the WD40 domain mediate tomosyn's binding to SNAP25 and are involved in tomosyn's organization on the plasma membrane.
Title: Differential interaction of tomosyn with syntaxin and SNAP25 depends on domains in the WD40 β-propeller core and determines its inhibitory activity.
Overexpression of transduced rat tomosyn 1 significantly impaired mouse hippocampus-dependent spatial memory & strategy in the water maze. It impaired paired-pulse facilitation in CA3 mossy fiber synapses.
Title: Neuron-specific expression of tomosyn1 in the mouse hippocampal dentate gyrus impairs spatial learning and memory.
multiple domains outside the R-SNARE of tomosyn are critical to the efficacy of inhibition by tomosyn on exocytotic secretion
Title: Structural and functional analysis of tomosyn identifies domains important in exocytotic regulation.
the interplay between tomosyn and synaptotagmin-1 underlies inhibitory control of Ca(2+)-dependent neurotransmitter release.
Title: Tomosyn inhibits synaptotagmin-1-mediated step of Ca2+-dependent neurotransmitter release through its N-terminal WD40 repeats.
tomosyn controls synaptic vesicle fusion positively by serving as a placeholder for VAMP2.
Title: The tail domain of tomosyn controls membrane fusion through tomosyn displacement by VAMP2.
conformational change of tomosyn mediated by the intramolecular interactions of the tail domain controls its inhibitory activity on the SNARE complex formation, leading to a regulated inhibition of neurotransmitter release.
Title: Reciprocal intramolecular interactions of tomosyn control its inhibitory activity on SNARE complex formation.
Tomosyn inhibits neurotransmitter release by catalyzing oligomerization of the SNARE complex through the N-terminal WD-40 repeat domain in addition to the inhibitory activity of the C-terminal (VAMP)-like domain.
Title: Dual inhibition of SNARE complex formation by tomosyn ensures controlled neurotransmitter release.
Can negatively regulate exocytosis independently of syntaxin.
Title: Amisyn regulates exocytosis and fusion pore stability by both syntaxin-dependent and syntaxin-independent mechanisms.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
