"we analyzed GABA receptor clusters in
unc-104 mutants... we could not detect any SNB-1-CFP in the dorsal nerve cord of
unc-104(
e1265) mutants (Fig. 5A)... In these animals, a faint and diffuse UNC-49-YFP signal was observed in dorsal muscle cells, but no clusters were present along the dorsal cord (Fig. 5B). Furthermore, along the ventral side of the
unc-104(
e1265) mutants, unusually large and irregular UNC-49-YFP aggregates were found along the ventral cord where residual numbers of synaptic vesicles accumulated (Fig. 5C). UNC-49-YFP clusters were also found directly in contact with the cell bodies of the GABA motor neurons (Fig. 5C, inset)."
