dop-3 reporters were expressed in neurons of the head, ventral cord and tail.
dop-3 reporter expression was also seen in some body-wall muscles, although this was weak and variable, and in two mechanosensory neurons known as PVD neurons. They were not expressed in the command interneurons that affect locomotion nor in any dopaminergic neurons, as expression of the RFP reporters for
dop-1 and
dop-3 did not overlap expression of integrated GFP reporters for
glr-1 or
dat-1, which label these two classes of cells, respectively.
