Different regions of synaptic vesicle membrane regulate VAMP2 conformation for the SNARE assembly

Nature Communications, 2020
Vesicle associated membrane protein 2 (VAMP2) contains a conserved SNARE motif that interacts with syntaxin-1 and SNAP25 for SNARE complex assembly. Here authors use in-cell NMR spectroscopy to describe the dynamic membrane association of VAMP2 SNARE ...

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Trans-SNARE Complex Assembly and Yeast Vacuole Membrane Fusion

, 2007
cis-SNARE complexes (anchored in one membrane) are disassembled by Sec17p (α-SNAP) and Sec18p (NSF), permitting the unpaired SNAREs to assemble in trans. We now report a direct assay of trans-SNARE complex formation during yeast vacuole docking.

Synthesis and Analysis of Modified SNARE Proteins with Respect to Assembly and Disassembly of the SNARE Complex [PDF]

, 2016
In this thesis, the first aim was to synthesise an inhibitor for the alpha-SNAP/NSF-mediated disassembly reaction of the SNARE complex. Based on identified interaction sites between alpha-SNAP and Synaptobrevin-2, suitable sequence positions (D51, E55 ...

Structural principles of SNARE complex recognition by the AAA+ protein NSF

eLife, 2018
The recycling of SNARE proteins following complex formation and membrane fusion is an essential process in eukaryotic trafficking. A highly conserved AAA+ protein, NSF (N-ethylmaleimide sensitive factor) and an adaptor protein, SNAP (soluble NSF ...

Helical extension of the neuronal SNARE complex into the membrane [PDF]

Nature, 2009
Neurotransmission relies on synaptic vesicles fusing with the membrane of nerve cells to release their neurotransmitter content into the synaptic cleft, a process requiring the assembly of several members of the SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) family.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Effect of resveratrol on SNARE proteins expression and insulin resistance in skeletal muscle of diabetic rats [PDF]

Iranian Journal of Basic Medical Sciences, 2019
Objective(s): Soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex proteins are involved in membrane trafficking. The expression of isoforms of SNAP-23, syntaxin-4, and VAMP-2 is significantly done in skeletal muscles ...

PARP inhibitors induce a senescence phenotype in non‐small cell lung carcinoma cell lines

FEBS Open Bio, EarlyView.
Talazoparib is the most potent inducer of senescence among different PARP1 inhibitors in human NSCLC cells. In the absence of PARP, no senescence phenotype was observed, demonstrating that PARP1 is necessary for the induction of senescence by this inhibitor.

A Dynamic t-SNARE Complex [PDF]

Structure, 2008
Syntaxin-1/SNAP-25 heterodimers with 1:1 stoichiometry likely play a key role in neurotransmitter release but they have been difficult to characterize. In this issue of Structure, Weninger et al. present a beautiful single molecule spectroscopy study showing the dynamic nature of these heterodimers and how they are influenced by other factors.
