Major synaptic vesicle protein p38; MRX96; MRXSYP; Syn p38; Synaptophysin; Syp; SYPH; SYPH_HUMAN; SypI;



Purified recombinant fragment of human SYP expressed in E. Coli.


Expressed in the brain, with expression in the hippocampus, the neuropil in the dentate gyrus, where expression is higher in the outer half of the molecular layer than in the inner half, and in the neuropil of CA4 and CA3.

Synaptophysin (p38) is an integral membrane protein of small synaptic vesicles in brain and endocrine cells.Synaptophysin contains four transmembrane domains that form a hexameric channel or gap junction-like pore. 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. Synaptophysin is also responsible for targeting synaptobrevin 2/VAMP2 to synaptic vesicles, a critical component of the fusion complex.

Research Backgrounds


Possibly involved in structural functions as organizing other membrane components or in targeting the vesicles to the plasma membrane. Involved in the regulation of short-term and long-term synaptic plasticity (By similarity).


Ubiquitinated; mediated by SIAH1 or SIAH2 and leading to its subsequent proteasomal degradation.

Tissue Specificity:

Expressed in the brain, with expression in the hippocampus, the neuropil in the dentate gyrus, where expression is higher in the outer half of the molecular layer than in the inner half, and in the neuropil of CA4 and CA3.

Subunit Structure:

Homohexamer or homotetramer. Interacts with SRCIN1. Interacts with VAMP2; the interaction is inhibit by interaction of VAPM2 with SEPT8 (By similarity).


The calcium-binding activity is thought to be localized in the cytoplasmic tail of the protein.

Belongs to the synaptophysin/synaptobrevin family.
