Snap91 - synaptosome associated protein 91

Enables several functions, including SH2 domain binding activity; anion binding activity; and clathrin binding activity. Involved in several processes, including negative regulation of phospholipase activity; positive regulation of cellular component organization; and positive regulation of synaptic vesicle clustering. Located in several cellular components, including cytoplasmic vesicle; postsynaptic density; and presynaptic active zone membrane. Is active in Schaffer collateral - CA1 synapse; parallel fiber to Purkinje cell synapse; and postsynaptic membrane. Is extrinsic component of presynaptic endocytic zone membrane. Biomarker of middle cerebral artery infarction. Orthologous to human SNAP91 (synaptosome associated protein 91). [provided by Alliance of Genome Resources, Apr 2022]
