unc-103::GFP construct expressed broadly in the head and ventral cord neurons in both males and hermaphrodites. In the male tail the SPC motor neurons and the PCB postcloacal sensory neurons expressed the construct. Many neurons express the construct, but because of variability in cell position and cellular localization of the fusion protein in processes, the list of
unc-103-expressing cells is far from complete. In the head region ALA, ADL, ASK, AVH, AVJ, AIN, AVA, ASJ, SMDD, SIA, ADE, and AVD express the construct. In the tail region PHA, DVC, ALN, and PVP express the construct. The
unc-103 fusion protein accumulates extensively in the processes of many ventral cord neurons; however, only some cells in the AS class of excitatory neurons was identified. In the adult hermaphrodite HSN expresses the
unc-103::gfp construct.
