Synaptophysin (7H12) Mouse mAb (IF Formulated) recognizes endogenous levels of total synaptophysin protein.
Human, Mouse, Rat
Monoclonal antibody is produced by immunizing animals with a recombinant protein specific to the carboxy terminus of human synaptophysin protein.
Synaptophysin (SYP) is a neuronal synaptic vesicle glycoprotein that is expressed in neuroendocrine cells and neoplasms (1). Synaptophysin contains four transmembrane domains that form a hexameric channel or gap junction-like pore (2). Synaptophysin binds to the SNARE protein synaptobrevin/VAMP, which prevents the inclusion of synaptobrevin in the synaptic vesicle fusion complex and creates a pool of synaptobrevin for exocytosis when synapse activity increases (3). Synaptophysin is also responsible for targeting synaptobrevin 2/VAMP2 to synaptic vesicles, a critical component of the fusion complex (4).
