Tetanus toxin is the tetanus toxin produced by the anaerobic bacillus?Clostridium tetani.
Tetanus toxin from Clostridium tetani has been used as the exocytosis inhibitor/Golgi-dependent secretion to examine whether secretory carrier membrane protein (SCAMP5) stimulated α-synuclein secretion via the conventional Golgi-dependent pathway. It has also been used in peripheral blood mononuclear cells (PBMCs) culture for?T?cell?proliferation screening.
Tetanus toxin is also known as tetanospasmin. It is a 150-kDa protein, produced by Clostridium tetani. This protein consists of a light and a heavy chain.
Binds to polysialogangliosides acceptors on surface of all peripheral presynaptic nerve terminals. Internalized by receptor-mediated endocytosis and carried to spinal cord and brain by transsynaptic retrograde transport. Blocks the release of glycine from inhibitory interneurons of the spinal cord. Cleaves synaptobrevin (VAMP-2), and blocks synaptic vesicle exocytosis in vivo.
