Evaluation of synaptotagmin‐1 action models by all‐atom molecular dynamics simulations

FEBS Open Bio
Neurotransmitter release is triggered in microseconds by the two C2 domains of the Ca2+ sensor synaptotagmin‐1 and by SNARE complexes, which form four‐helix bundles that bridge the vesicle and plasma membranes. The synaptotagmin‐1 C2B domain binds to the

Current status and future directions of botulinum neurotoxins for targeting pain processing. [PDF]

, 2015
Current evidence suggests that botulinum neurotoxins (BoNTs) A1 and B1, given locally into peripheral tissues such as skin, muscles, and joints, alter nociceptive processing otherwise initiated by inflammation or nerve injury in animal models and humans.

Impact of organic pollutants on phenotype and gene expression in human breast cancer cells

Journal of Applied Toxicology, Volume 46, Issue 5, Page 1487-1505, May 2026.
ABSTRACT Human exposure to industrial chemical compounds is widespread and, although often beneficial, prolonged contact may contribute to disease development, including cancer. While many studies have shown organic pollutants (OP) are cytotoxic, few have explored how long‐term exposure alters cell phenotype.

SYT13: An underestimated synaptotagmin

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research
Synaptotagmin-13 (SYT13) is a non-canonical member of the of synaptotagmin family that, canonical synaptotagmins, doesn't contain Ca2+ binding sites, but still appears to play a key role in the control of different cellular processes such as vesicle transport, cell migration, signaling and cell development.

Reduction in Synaptic Vesicle Protein Abundance but Increased Amounts of Nsg2 and Lpcat1 in Cerebral Cortices Without the Endosomal SNARE Proteins Vti1a and Vti1b

PROTEOMICS, Volume 26, Issue 5, Page 86-97, May 2026.
ABSTRACT Absence of the endosomal SNAREs vti1a and vti1b results in perinatal death and severe neuronal phenotypes in mice, while lack of one of these proteins results in minor phenotypes. Proteomic differences were investigated to obtain a deeper insight into processes in which vti1a and vti1b are involved.

Synaptotagmin 7 docks synaptic vesicles to support facilitation and Doc2α-triggered asynchronous release

eLife
Despite decades of intense study, the molecular basis of asynchronous neurotransmitter release remains enigmatic. Synaptotagmin (syt) 7 and Doc2 have both been proposed as Ca2+ sensors that trigger this mode of exocytosis, but conflicting findings have ...

PIP4K2A regulates intracellular cholesterol transport through modulating PI(4,5)P2 homeostasis

Journal of Lipid Research, 2018
The transport of LDL-derived cholesterol from lysosomes to peroxisomes is facilitated by membrane contacts formed between the lysosomal protein synaptotagmin VII and the peroxisomal lipid phosphatidylinositol 4, 5-bisphosphate [PI(4,5)P2].

MSM/RD: Coupling Markov state models of molecular kinetics with reaction-diffusion simulations [PDF]

, 2018
Molecular dynamics (MD) simulations can model the interactions between macromolecules with high spatiotemporal resolution but at a high computational cost. By combining high-throughput MD with Markov state models (MSMs), it is now possible to obtain long-

Serum Proteomic Analysis Using Gel‐Based Liquid Chromatography Tandem Mass Spectrometry Reveals Differences Between Canine Oral Malignancies and Non‐Malignant Conditions

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study establishes a GeLC‐MS/MS‐based serum proteomics workflow for canine oral oncology to differentiate malignancies from non‐malignant conditions. Comprehensive protein profiling, pathway analysis and protein–drug interaction mapping reveal candidate biomarkers and insights into the pathogenesis of canine oral cancers.

Distinct fusion properties of synaptotagmin-1 and synaptotagmin-7 bearing dense core granules

Molecular Biology of the Cell, 2014
Adrenal chromaffin cells release hormones and neuropeptides that are essential for physiological homeostasis. During this process, secretory granules fuse with the plasma membrane and deliver their cargo to the extracellular space. It was once believed that fusion was the final regulated step in exocytosis, resulting in uniform and total release of ...
