Synaptotagmin 7 functions as a Ca2+-sensor for synaptic vesicle replenishment

open access: yeseLife, 2014
Synaptotagmin (syt) 7 is one of three syt isoforms found in all metazoans; it is ubiquitously expressed, yet its function in neurons remains obscure. Here, we resolved Ca2+-dependent and Ca2+-independent synaptic vesicle (SV) replenishment pathways, and ...

Expression of synaptotagmin VIII in rat kidney

open access: yes, 1998
The synaptotagmins are a family of integral membrane proteins proposed to function as regulators of both exocytosis and endocytosis. Here, we have used immunochemical techniques and RT-PCR to assess sites of renal expression of synaptotagmin VIII.

Models of synaptotagmin‐1 to trigger Ca2+‐dependent vesicle fusion

open access: yesFEBS Letters, 2018
Vesicles in neurons and neuroendocrine cells store neurotransmitters and peptide hormones, which are released by vesicle fusion in response to Ca2+‐evoking stimuli.

Synaptotagmin: fusogenic role for calcium sensor?

open access: yes, 2006
Two recent studies focusing on synaptotagmin-1's role in synaptic vesicle fusion suggest that it may be key in bringing vesicle and target membranes together and in promoting SNARE assembly.

Synaptotagmin VII as a Plasma Membrane Ca2+ Sensor in Exocytosis [PDF]

open access: yes, 2001
Synaptotagmins I and II are Ca2+ binding proteins of synaptic vesicles essential for fast Ca2+-triggered neurotransmitter release. However, central synapses and neuroendocrine cells lacking these synaptotagmins still exhibit Ca2+-evoked exocytosis.

Concurrent Binding of Complexin and Synaptotagmin to Liposome-Embedded SNARE Complexes

open access: yes, 2015
Synaptotagmin and complexin regulate SNARE-mediated synaptic vesicle exocytosis. It has been proposed that complexin clamps membrane fusion and that Ca2+-synaptotagmin displaces complexin from SNARE complexes to relieve this clamping activity.

Unraveling the Functions of Synaptotagmin and Munc13 in Neurotransmitter Release [PDF]

open access: yes, 2017
Neurotransmitter release is a central event in interneuronal communication. The release machinery includes three SNAREs (soluble N-ethylmaleimide sensitive factor adaptor protein receptor) and Munc18-1 as core components.

SNAP25 disease mutations change the energy landscape for synaptic exocytosis due to aberrant SNARE interactions

open access: yeseLife
SNAP25 is one of three neuronal SNAREs driving synaptic vesicle exocytosis. We studied three mutations in SNAP25 that cause epileptic encephalopathy: V48F, and D166Y in the synaptotagmin-1 (Syt1)-binding interface, and I67N, which destabilizes the SNARE ...

Isoquercitrin and localization of synaptotagmin-1.

open access: yes, 2012
Left, The immuno-staining images show that synaptotagmin-1 localizes especially at spots along the neurites induced by isoquercitrin (Q) alone or combined with Rho inhibitors (Y-27632, C3 transferase). Green = synaptotagmin-1, blue = nuclei.
