Synaptophysin is an integral membrane protein of small synaptic vesicles in brain and endocrine cells (1). Synaptophysin (syp I) is a synaptic vesicle membrane protein that constitutes approximately 7% of the total vesicle protein. Multiple lines of evidence implicate syp I in a number of nerve terminal functions (2). Synaptophysin is one of the most abundant membrane proteins of small synaptic vesicles. In mature nerve terminals it forms a complex with the vesicular membrane protein synaptobrevin, which appears to modulate synaptobrevin's interaction with the plasma membrane-associated proteins syntaxin and SNAP25 to form the SNARE complex as a prerequisite for membrane fusion. It has been shown that synaptobrevin is preferentially cleaved by tetanus toxin while bound to synaptophysin or when existing as a homodimer (3). data suggest that synaptophysin is released from the Golgi apparatus in a vesicular form, after glycosylation, and is then transported to nerve endings by a mechanism which requires integrity of microtubules (4).
