ACR-2::GFP showed mostly diffused localization on neuronal soma, as well as processes in the ventral cord, sublateral cords, and nerve ring. In the ventral cord, expression of ACR-2::GFP was specifically observed in the VA, VB, DA, and DB motor neurons as reported previously (Jospin et al., 2009). Several additional cells (e.g., SDQ, vulva muscles) also expressed ACR-2::GFP, presumably because of the use of a longer promoter and inclusion of intronic sequences. However, staining of ACR-2::GFP was not seen in the dorsal nerve cord. Because the axonal processes of DA and DB motor neurons are major constituents of the dorsal nerve cord, lack of ACR-2::GFP signals in the dorsal nerve cord indicates that ACR-2 is unlikely to localize to presynaptic sites of these motor neurons.
