Synaptobrevin-like protein 1 (SYBL1), also known as vesicle-associated membrane protein 7 (VAMP7), is a protein that in humans is encoded by the VAMP7, or SYBL1, gene. [4] [5] [6]
SYBL1 is a transmembrane protein that is a member of the soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) family. SYBL1 localizes to late endosomes and lysosomes and is involved in the fusion of transport vesicles to their target membranes. [6]
SYBL1 has been shown to interact with SNAP23 [7] [8] and AP3D1. [7]
SNARE proteins – "SNAPREceptor" – are a large protein family consisting of at least 24 members in yeasts, more than 60 members in mammalian cells, and some numbers in plants. The primary role of SNARE proteins is to mediate vesicle fusion – the fusion of vesicles with the target membrane; this notably mediates exocytosis, but can also mediate the fusion of vesicles with membrane-bound compartments. The best studied SNAREs are those that mediate the neurotransmitter release of synaptic vesicles in neurons. These neuronal SNAREs are the targets of the neurotoxins responsible for botulism and tetanus produced by certain bacteria.
Vesicle associated membrane proteins (VAMP) are a family of SNARE proteins with similar structure, and are mostly involved in vesicle fusion.
Synaptobrevins are small integral membrane proteins of secretory vesicles with molecular weight of 18 kilodalton (kDa) that are part of the vesicle-associated membrane protein (VAMP) family.
Synaptosomal-associated protein 23 is a protein that in humans is encoded by the SNAP23 gene. Two alternative transcript variants encoding different protein isoforms have been described for this gene.
Syntaxin-4 is a protein that in humans is encoded by the STX4 gene.
Vesicle-associated membrane protein 2 (VAMP2) is a protein that in humans is encoded by the VAMP2 gene.
Syntaxin-7 is a protein that in humans is encoded by the STX7 gene.
Syntaxin-6 is a protein that in humans is encoded by the STX6 gene.
N-ethylmaleimide-sensitive factor Attachment Protein Alpha, also known as SNAP-α, is a SNAP protein that is involved in the intra-cellular trafficking and fusing of vesicles to target membranes in cells.

Vesicle-associated membrane protein 5 also known as VAMP5 is a human gene which encodes a member of the synaptobrevin protein family.
Syntaxin 3, also known as STX3, is a protein which in humans is encoded by the STX3 gene.
Munc-18 proteins are the mammalian homologue of UNC-18 and are a member of the Sec1/Munc18-like (SM) protein family. Munc-18 proteins have been identified as essential components of the synaptic vesicle fusion protein complex and are crucial for the regulated exocytosis of neurons and neuroendocrine cells.
Syntaxin-10 (STX10) is a SNARE protein that is encoded by the STX10 gene. This protein is found in most vertebrates but is noticeably absent from mice. As with other SNARE proteins, STX10 facilitates vesicle fusion and thus is important for intracellular trafficking of proteins and other cellular components. More specifically, STX10 has been implicated in endosome to Golgi trafficking of the mannose 6-phosphate receptor and glucose transporter type 4.
Vesicle transport through interaction with t-SNAREs homolog 1A is a protein that in humans is encoded by the VTI1A gene.
