Synaptotagmin I and neurexin I mRNAs, coding for proteins involved in neurotransmitter secretion, become detectable in primary sympathetic ganglia shortly after initial induction of the noradrenergic transmitter phenotype.

New insights into epileptic spasm generation and treatment from the TTX animal model
Abstract Currently, we have an incomplete understanding of the mechanisms underlying infantile epileptic spasms syndrome (IESS). However, over the past decade, significant efforts have been made to develop IESS animal models to provide much‐needed mechanistic information for therapy development.

Calcium-dependent oligomerization of synaptotagmins I and II. Synaptotagmins I and II are localized on the same synaptic vesicle and heterodimerize in the presence of calcium. [PDF]
Synaptotagmins constitute a large family of membrane proteins characterized by their distinct distributions and different biochemical features. Genetic evidence suggests that members of this protein family are likely to function as calcium sensors in calcium-regulated events in neurons, although the precise molecular mechanism remains ill defined. Here

Molecular Aspects of Secretory Granule Exocytosis by Neurons and Endocrine Cells [PDF]
Neuronal communication and endocrine signaling are fundamental for integrating the function of tissues and cells in the body. Hormones released by endocrine cells are transported to the target cells through the circulation.

Synaptic vesicle proteins and active zone plasticity
Neurotransmitter is released from synaptic vesicles at the highly specialized presynaptic active zone. The complex molecular architecture of active zones mediates the speed, precision and plasticity of synaptic transmission.

Overexpression of synaptotagmin does not rescue unc-41 mutants.
(A) Images of synaptotagmin (SNT-1::GFP) under different overexpression conditions. All images were taken at identical settings. High levels of tagged synaptotagmin were observed in the nerve rings of snt-1(md290) or unc-41(e268) mutants when injected at

ABSTRACT Insulin secretion is a complex, vesicular transport process. Rab34 is a key regulator of intracellular vesicle transport; however, its role in insulin secretion has not yet been reported. miRNA‐9 is vital for the development and progression of the diagnosis and treatment of type 2 diabetes. This study aimed to investigate whether miR‐9 targets

Synaptotagmin I Synchronizes Transmitter Release in Mouse Hippocampal Neurons [PDF]
We have asked whether loss of the Ca2+sensor protein synaptotagmin I influences the total amount of neurotransmitter released after a presynaptic action potential. Hippocampal neurons from synaptotagmin I knock-out mice had a greatly reduced fast synchronous component of glutamate release, as reported previously.

Calcium-independent stimulation of membrane fusion and SNAREpin formation by synaptotagmin I
Ñeurotransmitter release requires the direct coupling of the calcium sensor with the machinery for membrane fusion. SNARE proteins comprise the minimal fusion machinery, and synaptotagmin I, a synaptic vesicle protein, is the primary candidate for the ...
