Fig. 6. The N-terminal domain of Stx7 is responsible for proper sorting of Stx7 to a subset of recycling SVs.

Fig. 6

a Schematic diagram of full length Stx7-SEP, Stx7-SEP lacking the N-terminal domain (Stx7-ΔN-SEP), and Stx7-SEP lacking SNARE motif (Stx7-ΔSNARE-SEP). b Distribution of Stx7-SEP, Stx7-ΔN-SEP, and Stx7-Δ-SNARE-SEP in transfected neurons. Box-whisker plots showing the surface fraction of Stx7-SEP and truncated mutants (c) and vesicular pHs of vesicles carrying respective SEPs (d). Note that vesicular pH of Stx7-ΔSNARE-SEP could not be calculated, since it was exclusively expressed at the cell surface (N.D. indicates ‘not determined’). e Responses of Stx7-SEP (black traces) and Stx7-ΔN-SEP (red traces) upon 10 Hz (left panels) and 40 Hz stimulation (right panels). f Responses of Stx7-ΔN-SEP upon 10-Hz stimulation in control (black) and after TeNT treatment (red). g Responses of Stx7-ΔN-SEP upon 40 Hz stimulation in control (black) and after Lat-A treatment (red).
