(f) Presynaptic localization of mouse CaBP4 (red) demonstrated by covisualization with a presynaptic protein (PSD95; green). Arrows indicate rod spherules and cone pedicles. (g) Colocalization of synaptic vesicle proteins SV2 and synaptophysin (green) with mouse CaBP4 (red).
Biochemical evidence showing mouse CaBP4 (red) localization to the presynaptic region based on co-localization with the PSD95 marker (green).
