ERP-1 is expressed in cholinergic and GABAergic motor neurons. Fluorescent micrographs, assembled from smaller images, of each one representative animal expressing GFP from the erp-1 promoter (top right) or channelrhodopsin-2 (ChR2)::YFP (i.e., associated with membranes) from the unc-17 promoter (bottom left; specific for cholinergic neurons). Tentative assignment of the ventral nerve cord neuronal cell bodies (starting from the midbody region, i.e., the vulva) shows that ERP-1 is expressed in cholinergic (red lines and neuron names) and GABAergic (green lines and names) neurons, while punc-17 is restricted to the cholinergic neurons only. See Supplementary Figure S2 for a close-up of the vulva region.
