Localization of pre-synaptic proteins is disrupted in mbl-1 mutants. (A) Schematic of DA9 and wild-type localization of RAB-3. (B-G) Co-localization of RAB-3 and UNC-10 in wild type (B-D) and mbl-1(tm1563) (E-G). (wyEx3709). (H-M) RAB-3 and the active zone protein SYD-2 in wild type (H-J) and mbl-1(tm1563) (K-M). Transgene used is wyEx2055. Scale bar represents 10 μm.
