Most, if not all, GABAergic motor neurons expressed Pmec-15::GFP. In addition, Pmec-15::GFP was expressed in many non-GABAergic motor neurons in the ventral nerve cord, indicating that
mec-15 is also expressed in cholinergic motor neurons. Pmec-15::GFP was also expressed in neurons in the head and tail as well as in other tissues as reported previously.
