The diversity of synaptotagmin isoforms

Current Opinion in Neurobiology, 2020
The synaptotagmin family of molecules is known for regulating calcium-dependent membrane fusion events. Mice and humans express 17 synaptotagmin isoforms, where most studies have focused on isoforms 1, 2, and 7, which are involved in synaptic vesicle exocytosis. Recent work has highlighted how brain function relies on additional isoforms, with roles in

How Synaptotagmin Promotes Membrane Fusion [PDF]

open access: yesScience, 2007
Synaptic vesicles loaded with neurotransmitters are exocytosed in a soluble N -ethylmaleimide–sensitive factor attachment protein receptor (SNARE)–dependent manner after presynaptic depolarization induces calcium ion (Ca 2+ ) influx. The Ca

Synaptotagmin-1 undergoes phase separation to regulate its calcium-sensitive oligomerization

Journal of Cell Biology
Zhu et al. reveal that Synaptotagmin 1 (Syt1) forms condensate to interact with negatively charged lipid bilayers and recruit SNARE complexes and complexin.

Synaptotagmin and neurotransmitter release

Cell, 1993
William M. DeBello,’ Heinrich Bet Torri-Tarelli et al., 1985), and that this exocytosis is trig- gered by a rise in the concentration of Ca within presynap- tic terminals (Miledi, 1973). The source of this triggering Ca is the voltage-gated Ca channel, which is found in close proximity to the sites of exocytosis (Augustine et al., 1987).

Synaptotagmin regulates mast cell functions

Immunological Reviews, 2001
Summary: Synaptotagmin(s) (Syts), are products of a gene family implicated in the control of Ca2+‐dependent exocytosis. Mast cells, specialized secretory cells that release mediators of inflammatory and allergic reactions in a process of regulated exocytosis, express Syt homologues and SNAREs (Soluble NSF Attachment proteins Receptors), which together ...
