Synaptotagmin 13: Structure and expression of a novel synaptotagmin

open access: yesEuropean Journal of Cell Biology, 2001
Synaptotagmins represent a family of putative vesicular trafficking proteins. With synaptotagmin 13, we have now identified a novel synaptotagmin, making this one of the largest families of trafficking proteins. Similar to synaptotagmins 3, 4, 6, 7, 9, and 11, synaptotagmin 13 is expressed at highest levels in brain but is also detectable at lower ...

SYT1-Associated Neurodevelopmental Disorder: A Narrative Review

open access: yesChildren, 2022
Synaptic dysregulations often result in damaging effects on the central nervous system, resulting in a wide range of brain and neurodevelopment disorders that are caused by mutations disrupting synaptic proteins. SYT1, an identified synaptotagmin protein,

Synaptotagmin 1 directs repetitive release by coupling vesicle exocytosis to the Rab3 cycle

open access: yeseLife, 2015
In response to Ca2+ influx, a synapse needs to release neurotransmitters quickly while immediately preparing for repeat firing. How this harmonization is achieved is not known. In this study, we found that the Ca2+ sensor synaptotagmin 1 orchestrates the

Synaptotagmin 13 is neuroprotective across motor neuron diseases

open access: yesActa Neuropathologica, 2020
In amyotrophic lateral sclerosis (ALS) and spinal muscular atrophy (SMA), spinal and lower brainstem motor neurons degenerate, but some motor neuron subtypes are spared, including oculomotor neurons (OMNs).

A synaptotagmin suppressor screen indicates SNARE binding controls the timing and Ca2+ cooperativity of vesicle fusion

open access: yeseLife, 2017
The synaptic vesicle Ca2+ sensor Synaptotagmin binds Ca2+ through its two C2 domains to trigger membrane interactions. Beyond membrane insertion by the C2 domains, other requirements for Synaptotagmin activity are still being elucidated.

The involvement of actin, calcium channels and exocytosis proteins in somato-dendritic oxytocin and vasopressin release [PDF]

open access: yes, 2012
Hypothalamic magnocellular neurons release vasopressin and oxytocin not only from their axon terminals into the blood, but also from their somata and dendrites into the extracellular space of the brain, and this can be regulated independently ...

Expression and distribution of synaptotagmin family members in the zebrafish retina

open access: yesThe Journal of comparative neurology, 2021
Synaptotagmins belong to a large family of proteins. Although various synaptotagmins have been implicated as Ca2+ sensors for vesicle replenishment and release at conventional synapses, their roles at retinal ribbon synapses remain incompletely ...

Coming together to define membrane contact sites. [PDF]

open access: yes, 2019
Close proximities between organelles have been described for decades. However, only recently a specific field dealing with organelle communication at membrane contact sites has gained wide acceptance, attracting scientists from multiple areas of cell ...

Synaptotagmin gene content of the sequenced genomes

open access: yesBMC Genomics, 2004
Background Synaptotagmins exist as a large gene family in mammals. There is much interest in the function of certain family members which act crucially in the regulated synaptic vesicle exocytosis required for efficient neurotransmission.

Creating Contacts Between Replication and Movement at Plasmodesmata – A Role for Membrane Contact Sites in Plant Virus Infections?

open access: yesFrontiers in Plant Science, 2020
To infect their hosts and cause disease, plant viruses must replicate within cells and move throughout the plant both locally and systemically. RNA virus replication occurs on the surface of various cellular membranes, whose shape and composition become ...
