part of part of in taxon cortical cytoskeleton cytoskeleton of presynaptic active zone presynaptic cytoskeletal matrix assembled at active zones synaptic ribbon presynaptic cytoskeletal matrix The specialized cytoskeletal matrix of the presynaptic active zone. It has specialized functions in organizing synaptic events such as immobilisation or translocation of synaptic vesicles, and assembling active zone components. It is believed to form a molecular scaffold that organizes neurotransmitter release sites. pre-synaptic ribbon active zone cytomatrix GO:0048788 NIF_Subcellular:sao1470121605 pre-synaptic cytoskeletal matrix assembled at active zones CAZ presynaptic ribbon ribbon pre-synaptic dense body T-bar ribbon presynaptic cytomatrix assembled at active zones T-bar presynaptic dense body presynaptic active zone cytoplasmic component presynaptic cytoskeleton Eumetazoa
