    basic FUNCTION
  • SNAP91 and PICALM function as endocytic accessory proteins at synapses, but each may regulate distinct clathrin pathways
  • required for the proper assembly of synaptic vesicles via clathrin-mediated endocytosis
  • SNAP91 and PICALM play critical roles in establishing the polarity and controlling the growth of axons and dendrites in embryonic hippocampal neurons
  • having functions in intracellular trafficking that are essential in the growth of neurons
  • SNAP91 and PICALM, while similar in their domain structures and biochemical properties, are in fact dedicated to separate trafficking pathways in neurons
  • its function in retrieving surface-stranded synaptobrevin from the neuronal surface may be related to its role in neurodegenerative disorders, including Alzheimer disease
  • its levels and synaptic distribution are highly sensitive to neuronal activity
  • involved in the assembly of clathrin coated vesicles in synaptic vesicle endocytosis
  • SNAP91 and PICALM are cargo-specific adaptors for synaptobrevin endocytosis, in the central nervous system
  • SNAP91 and PICALM not only regulate the assembly of the endocytic machinery but also act as sorters for a subset of SNAREs, the vesicle-associated membrane proteins (VAMPs), most notably VAMP/synaptobrevin 2 at synapses
  • SNAP91 and PICALM regulate the assembly of clathrin-coated vesicles (CCVs), which mediate diverse intracellular trafficking processes, including synaptic vesicle (SV) recycling at the synapse
  • SNAP91 and PICALM in the presynaptic terminals of hippocampal neurons, have a similar role in regulating synaptic vesicles
