cah-2 shows strong neuronal expression in adults. Using a pBAG::mCherry marker, was shown that
cah-2, but not apparently any of the other five cah genes, was expressed in BAG.
cah-2 was also expressed in a set of four quadrant head neurons, other unidentified head neurons, the canal neurons CANL/R, whose processes run parallel to the tracts of the excretory cell, and a pair of tail neurons.
