Figure 8. Model of the synaptic tiling in DA8/DA9.
PLX-1 is localized at the synaptic tiling border dependent on both SMP-1 in DA9 and unknown molecule(s) in DA8. Localized and activated PLX-1 inhibits synapse formation in DA9 as well as restricts the activity or localization of unknown molecule(s) in DA8. See text for detail.
