Supplementary information

Synaptotagmin VII also known as Syt7 is a calcium-sensitive protein that plays an important role in the process of vesicle trafficking and membrane fusion. It has a molecular weight of approximately 48 kDa. This protein belongs to the synaptotagmin family with several isoforms expressed in different tissues. Synaptotagmin VII is mainly found in the cerebrum and other parts of the central nervous system where it regulates neurotransmitter release. Its calcium-binding domains are essential for its function in synaptic vesicle exocytosis and endocytosis.
Biological function summary

The function of Synaptotagmin VII involves the facilitation of calcium-dependent exocytosis. It acts as a calcium sensor that triggers the rapid release of neurotransmitters in response to synaptic activity. Synaptotagmin VII forms part of a larger protein complex that includes SNARE proteins which are directly involved in the docking and fusion of synaptic vesicles. Synaptotagmin VII's action ensures efficient communication between neurons by ensuring that neurotransmitter release occurs at the right moment when triggered by a rise in intracellular calcium levels.

Pathways

Synaptotagmin VII is important for pathways that involve synaptic vesicle cycling which includes the calcium-triggered synaptic vesicle exocytosis pathway. It interacts with other proteins such as syntaxin and SNAP-25 as part of the SNARE complex which mediates vesicle fusion. Synaptotagmin VII's function in these pathways ensures that neuronal signaling is rapid and tightly regulated a vital component for maintaining synaptic plasticity and normal brain function.

Alterations in Synaptotagmin VII expression or function can be linked to neurological conditions such as epilepsy and certain forms of cognitive dysfunction. Dysregulation of Synaptotagmin VII may lead to impaired neurotransmission contributing to the pathophysiology of these disorders. Moreover its connection with proteins in the SNARE complex hints at its potential involvement in diseases where these pathways are disrupted. For instance an imbalance in synaptotagmin and SNARE protein interactions can lead to defective neurotransmitter release potentially exacerbating synaptic abnormalities observed in some seizure disorders.

Target data

Ca(2+) sensor involved in Ca(2+)-dependent exocytosis of secretory and synaptic vesicles through Ca(2+) and phospholipid binding to the C2 domain. Ca(2+) induces binding of the C2-domains to phospholipid membranes and to assembled SNARE-complexes; both actions contribute to triggering exocytosis. SYT7 binds Ca(2+) with high affinity and slow kinetics compared to other synaptotagmins (PubMed : 26738595). Involved in Ca(2+)-triggered lysosomal exocytosis, a major component of the plasma membrane repair (By similarity). Ca(2+)-regulated delivery of lysosomal membranes to the cell surface is also involved in the phagocytic uptake of particles by macrophages (PubMed : 16982801, PubMed : 21041449). Ca(2+)-triggered lysosomal exocytosis also plays a role in bone remodeling by regulating secretory pathways in osteoclasts and osteoblasts (PubMed : 18539119). Involved in cholesterol transport from lysosome to peroxisome by promoting membrane contacts between lysosomes and peroxisomes : probably acts by promoting vesicle fusion by binding phosphatidylinositol-4,5-bisphosphate on peroxisomal membranes (PubMed : 25860611). Acts as a key mediator of synaptic facilitation, a process also named short-term synaptic potentiation : synaptic facilitation takes place at synapses with a low initial release probability and is caused by influx of Ca(2+) into the axon terminal after spike generation, increasing the release probability of neurotransmitters (PubMed : 24569478, PubMed : 26738595). Probably mediates synaptic facilitation by directly increasing the probability of release (PubMed : 26738595). May also contribute to synaptic facilitation by regulating synaptic vesicle replenishment, a process required to ensure that synaptic vesicles are ready for the arrival of the next action potential : SYT7 is required for synaptic vesicle replenishment by acting as a sensor for Ca(2+) and by forming a complex with calmodulin (PubMed : 24569478). Also acts as a regulator of Ca(2+)-dependent insulin and glucagon secretion in beta-cells (PubMed : 18308938, PubMed : 19171650). Triggers exocytosis by promoting fusion pore opening and fusion pore expansion in chromaffin cells (PubMed : 20956309). Also regulates the secretion of some non-synaptic secretory granules of specialized cells (By similarity).
