Features：a modified cytosolic fragment of Stargazin (SGZ) increased SNR of optical minis. These variants exhibited narrower optical minis and improved surface trafficking as measured by ΔF/F on glutamate application. GPI and SGZ motifs that increase the SNR of synaptic signals, improve trafficking in cultured neurons, and improve iGluSnFR’s postsynaptic localization in vivo
