grld-1 was expressed in many cell types, including, muscles, epithelial cells and neurons. Coexpressing mCherry under the
opt-3 promoter,
grld-1 was found expressed in AVE.
grld-1 was also expressed in many of the neurons that are important for the nose-touch behavior, including the A-type motor neurons, the sensory neuron, ASH, and the
glr-1expressing interneurons AVA and AVD.
