\u3csup\u3e99m\u3c/sup\u3eTc-Labeled C2A Domain of Synaptotagmin I as a Target-Specific Molecular Probe for Noninvasive Imaging of Acute Myocardial Infarction [PDF]

open access: yes, 2006
: The exposure of phosphatidylserine (PtdS) is a common molecular marker for both apoptosis and necrosis and enables the simultaneous detection of these distinct modes of cell death. Our aim was to develop a radiotracer based on the PtdS-binding activity

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

open access: yesJournal of Applied Toxicology, EarlyView.
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.

Transmembrane tethering of synaptotagmin to synaptic vesicles controls multiple modes of neurotransmitter release [PDF]

open access: yes, 2014
Synaptotagmin 1 (Syt1) is a synaptic vesicle integral membrane protein that regulates neurotransmitter release by activating fast synchronous fusion and suppressing slower asynchronous release.

Plasmodesmata‐located proteins: The molecular hubs in noncell‐autonomous immunity

open access: yesNew Plant Protection, EarlyView.
Plasmodesmata serve as critical battlefields for plant immunity, regulated by diverse proteins. This article provides a comprehensive review of the regulatory mechanisms, challenges, and future directions concerning proteins located within plasmodesmata and their roles in plant defense responses.

Phosphatidylinositol 4,5-bisphosphate optical uncaging potentiates exocytosis

open access: yeseLife, 2017
Phosphatidylinositol-4,5-bisphosphate [PI(4,5)P2] is essential for exocytosis. Classical ways of manipulating PI(4,5)P2 levels are slower than its metabolism, making it difficult to distinguish effects of PI(4,5)P2 from those of its metabolites.

Epigallocatechin gallate inhibits SNARE‐dependent membrane fusion by blocking trans‐SNARE assembly

open access: yesFEBS Open Bio, 2022
Insulin secretion is a signal‐triggered process that requires membrane fusion between the secretory granules and plasma membrane in pancreatic β cells. The exocytosis of insulin is mediated by target‐soluble N‐ethylmaleimide sensitive factor attachment ...

Presynaptic congenital myasthenic syndrome with altered synaptic vesicle homeostasis linked to compound heterozygous sequence variants in RPH3A. [PDF]

open access: yes, 2018
BackgroundMonogenic defects of synaptic vesicle (SV) homeostasis have been implicated in many neurologic diseases, including autism, epilepsy, and movement disorders.

The C2A domain of synaptotagmin is an essential component of the calcium sensor for synaptic transmission

open access: yesPLoS ONE, 2020
The synaptic vesicle protein, synaptotagmin, is the principle Ca2+ sensor for synaptic transmission. Ca2+ influx into active nerve terminals is translated into neurotransmitter release by Ca2+ binding to synaptotagmin’s tandem C2 domains, triggering the ...

Molecular insights into electroreceptor ribbon synapses from differential gene expression in sturgeon lateral line organs

open access: yesJournal of Anatomy, EarlyView.
The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.

UNC-41/stonin functions with AP2 to recycle synaptic vesicles in Caenorhabditis elegans. [PDF]

open access: yesPLoS ONE, 2012
The recycling of synaptic vesicles requires the recovery of vesicle proteins and membrane. Members of the stonin protein family (Drosophila Stoned B, mammalian stonin 2) have been shown to link the synaptic vesicle protein synaptotagmin to the endocytic ...
