Mouse Monoclonal Antibody
Manufacturer: BD Biosciences 611880
Synaptophysin is a major integral membrane glycoprotein that was isolated from the presynaptic vesicles of neurons. The structure of synaptophysin includes four transmembrane domains (TMD), an N-temrinal glycosylation site, nine repeats of basic tetrapeptide motifs (GYGP), multiple collagenase sensitive sites (XGP), and several collagen-type tripeptides (GXX). Synaptophysin mRNA is expressed in nervous tissues, as well as many neuroendocrine tumor cell lines. In PC12 cells and brain synaptic vesicles, synaptophysin binds cholesterol, and cholesterol depletion blocks the biogenesis of synaptic-like microvesicles. In addition, synaptophysin binds dynamin in a Ca2+-dependent manner, and injection of peptides that disrupt this interaction decreases neurotransmitter release during high-frequency stimulation of squid neurons. This decrease in neurotransmitter release results from inhibition of synaptophysin-dependent vesicle retrieval. Thus, synaptophysin may have important roles in the biogenesis and recycling of synaptic vesicles. Synaptophysin is an integral membrane glycoprotein with a calculated molecular weight of 33kD, but has been reported to be observed at 38-42kD due to glycosylation.
