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. Homohexamer or homotetramer. Interacts with SRCIN1. Characteristic of a type of small (30-80 nm) neurosecretory vesicles, including presynaptic vesicles, but also vesicles of various neuroendocrine cells of both neuronal and epithelial phenotype. Belongs to the synaptophysin/synaptobrevin family. Note: This description may include information from UniProtKB.
