To trace the expression of LET-767, we generated a single-copy integrated strain for the translational expression of
let-767::gfp. The green fluorescence of LET-767::GFP was observed mainly in the intestine and hypodermis, the major sites for lipid synthesis and storage (Watts and Ristow, 2017). LET-767 is expressed on both the endoplasmic reticulum and lipid droplets.
