Snapshot of protein mobility in the synapse. A region within the synapse at the edge of the synaptic vesicle cluster is shown.
Organelles in grey represent synaptic vesicles (each ~40 nm in diameter). Various shapes correspond to different protein molecules, with each protein species having its own shape, as extracted from stuctural studies. The proteins are colored based on the speed of movement of every individual molecule in every position, from dark violet (the slowest one) to yellow (the fastest). Most proteins move slowly next to the synaptic vesicles, and are much faster in the vesicle-free region.
