observed robust ACS-4::GFP expression throughout development in all
larval stages and in adult worms. In addition to lipid droplet localization,
we observed that ACS-4::GFP is expressed in a range of other tissues, including
the pharynx, seam cells, dorsal and ventral nerve cords, and
other cells, likely neurons, in the head and tail (Supplemental Fig. 2).
Thus, ACS-4 appears to be a resident lipid droplet protein, although it
may function in other tissues in C. elegans as well.
