RIM localization is partially dependent on ELKS. A, The PDZ and C2A domains of RIM are sufficient for RIM localization. GFP (green) and ELKS (red) immunostaining in the ventral nerve cord of transgenic unc-10(md1117) animals expressing GFP-PDZC2ARIM (GFP-tagged RIM containing amino acids 627-974) or GFP-C2ARIM (GFP-tagged RIM containing amino acids 826-974) is shown. B, The localization of GFP-PDZC2ARIM is ELKS dependent. GFP (green) and ELKS (red) immunostaining in the ventral nerve cord of transgenic elks(js816); unc-10(md1117) expressing GFP-PDZC2ARIM. C, RIM localizes in the absence of ELKS and other active zone components. RIM immunostaining in the dorsal nerve cord of unc-13(s69); elks(js816), elks(js816); unc-2(e55), and elks(js816); syd-2(ju37) double-mutant animal is shown. Scale bars, 20 μm.
