Supplementary information

Vesicle-associated membrane protein 2 (VAMP2) also known as synaptobrevin 2 is a member of the SNARE protein family with a molecular mass of approximately 13 kDa. VAMP2 plays an important role in vesicle trafficking and membrane fusion particularly in the nervous system. It is prominently expressed in the brain where it facilitates neurotransmitter release by forming SNARE complexes essential for synaptic vesicle fusion with the presynaptic membrane.
Biological function summary

VAMP2 interacts with other SNARE proteins such as synaptosomal-associated protein 25 (SNAP-25) and syntaxin-1 to form stable complexes necessary for synaptic vesicle docking and exocytosis. As part of the SNARE complex VAMP2 contributes to the precise regulation of neurotransmitter release in neurons which is critical for synaptic transmission and plasticity. Its function is vital for the communication between neurons and proper brain function.

Pathways

VAMP2 plays a significant role in the synaptic vesicle cycle and neurotransmitter release pathways. It is central to the exocytosis pathway where it interacts with Rab3a a small GTPase that regulates vesicle docking. By participating in these pathways VAMP2 ensures efficient neurotransmission and contributes to neuronal communication processes. VAMP2's interaction with related proteins like SNAP-25 and syntaxin-1 highlights its importance in these synaptic processes.

VAMP2 has associations with conditions such as epilepsy and neurodegenerative diseases. Alterations in VAMP2 expression or function can disrupt normal neurotransmitter release impacting synaptic function and leading to neurological symptoms. VAMP2's relationship with SNAP-25 and syntaxin-1 further implicates it in these disorders as these proteins collectively regulate neural communication. Understanding VAMP2's role in these illnesses aids in the development of potential therapeutic strategies targeting SNARE complex dysfunctions.

General info

Function

Involved in the targeting and/or fusion of transport vesicles to their target membrane (By similarity). Major SNARE protein of synaptic vesicles which mediates fusion of synaptic vesicles to release neurotransmitters. Essential for fast vesicular exocytosis and activity-dependent neurotransmitter release as well as fast endocytosis that mediates rapid reuse of synaptic vesicles (By similarity) (PubMed : 30929742). Modulates the gating characteristics of the delayed rectifier voltage-dependent potassium channel KCNB1.

Sequence similarities

Belongs to the synaptobrevin family.

Post-translational modifications

Phosphorylated by PRKCZ in vitro and this phosphorylation is increased in the presence of WDFY2.. (Microbial infection) Targeted and hydrolyzed by C.botulinum neurotoxin type B (BoNT/B, botB) which hydrolyzes the 76-Gln-|-Phe-77 bond and probably inhibits neurotransmitter release (PubMed:7803399).. (Microbial infection) Targeted and hydrolyzed by C.botulinum neurotoxin type D (BoNT/D, botD) which probably hydrolyzes the 59-Lys-|-Leu-60 bond and inhibits neurotransmitter release (PubMed:22289120). Note that humans are not known to be infected by C.botulinum type D.. (Microbial infection) Targeted and hydrolyzed by C.botulinum neurotoxin type F (BoNT/F, botF) which hydrolyzes the 58-Gln-|-Lys-59 bond and probably inhibits neurotransmitter release (PubMed:19543288).. (Microbial infection) Targeted and hydrolyzed by C.tetani tetanus toxin (tetX) which hydrolyzes the 76-Gln-|-Phe-77 bond and probably inhibits neurotransmitter release (PubMed:7803399).
