Exploring the functional domain and the target of the tetanus toxin light chain in neurohypophysial terminals [PDF]

open access: yes, 1994
The tetanus toxin light chain blocks calcium induced vasopressin release from neurohypophysial nerve terminals. Here we show that histidine residue 233 within the putative zinc binding motif of the tetanus toxin light chain is essential for the ...

The release of inhibition model reproduces kinetics and plasticity of neurotransmitter release in central synapses

open access: yesCommunications Biology, 2023
Calcium-evoked release of neurotransmitters from synaptic vesicles (SVs) is catalysed by SNARE proteins. The predominant view is that, at rest, complete assembly of SNARE complexes is inhibited (‘clamped’) by synaptotagmin and complexin molecules ...

Implication of synaptotagmins 4 and 7 in activity-dependent somatodendritic dopamine release in the ventral midbrain

open access: yesOpen Biology, 2022
Dopamine (DA) neurons can release DA not just from axon terminals, but also from their somatodendritic (STD) compartment through a mechanism that is still incompletely understood. Using voltammetry in mouse mesencephalic brain slices, we find that STD DA

Cholinergic efferent synaptic transmission regulates the maturation of auditory hair cell ribbon synapses. [PDF]

open access: yes, 2013
Spontaneous electrical activity generated by developing sensory cells and neurons is crucial for the maturation of neural circuits. The full maturation of mammalian auditory inner hair cells (IHCs) depends on patterns of spontaneous action potentials ...

Autophagosomal membranes assemble at ER-plasma membrane contact sites

open access: yesMolecular & Cellular Oncology, 2017
The biogenesis of autophagosome, the double membrane bound organelle related to macro-autophagy, is a complex event requiring numerous key-proteins and membrane remodeling events.

A manual collection of Syt, Esyt, Rph3a, Rph3al, Doc2, and Dblc2 genes from 46 metazoan genomes - an open access resource for neuroscience and evolutionary biology

open access: yesBMC Genomics, 2010
Background Synaptotagmin proteins were first identified in nervous tissue, residing in synaptic vesicles. Synaptotagmins were subsequently found to form a large family, some members of which play important roles in calcium triggered exocytic events ...

The highly expressed calcium‐insensitive synaptotagmin‐11 and synaptotagmin‐13 modulate insulin secretion

open access: yesActa Physiologica, 2022
AbstractAimSYT11 and SYT13, two calcium‐insensitive synaptotagmins, are downregulated in islets from type 2 diabetic donors, but their function in insulin secretion is unknown. To address this, we investigated the physiological role of these two synaptotagmins in insulin‐secreting cells.MethodsCorrelations between gene expression levels were performed ...

The Arabidopsis synaptotagmin SYTA regulates the cell-to-cell movement of diverse plant viruses

open access: yesFrontiers in Plant Science, 2014
Synaptotagmins are a large gene family in animals that have been extensively characterized due to their role as calcium sensors to regulate synaptic vesicle exocytosis and endocytosis in neurons, and dense core vesicle exocytosis for hormone secretion ...

Doc2B acts as a calcium sensor for vesicle priming requiring synaptotagmin-1, Munc13-2 and SNAREs

open access: yeseLife, 2017
Doc2B is a cytosolic protein with binding sites for Munc13 and Tctex-1 (dynein light chain), and two C2-domains that bind to phospholipids, Ca2+ and SNAREs.

Sticking With It: ER-PM Membrane Contact Sites as a Coordinating Nexus for Regulating Lipids and Proteins at the Cell Cortex

open access: yesFrontiers in Cell and Developmental Biology, 2020
Membrane contact sites between the cortical endoplasmic reticulum (ER) and the plasma membrane (PM) provide a direct conduit for small molecule transfer and signaling between the two largest membranes of the cell.
