Predicted structural motifs of mouse Cidea and FSP27 based on sequence homology with mouse perilipin. FSP27 (amino acids 2–29) and Cidea (amino acids 2–28) show sequence similarity of 32% and 22%, respectively, with a portion of the adipophilin-like sequence of perilipin (amino acids 11–38, I). In perilipin, amino acids 120–152 (II) represents a section of the triacyglycerol shielding region that plays a role in shielding stored triacylglycerol from cytosolic lipases. It has a sequence similarity of 40% with FSP27 (amino acids 46–77) and 51% with Cidea (amino acids 38–69). Similarly, lipid droplet targeting and anchoring regions of perilipin (amino acids 313–352, III; and amino acids 365–391, IV) have sequence similarities of 40% and 30% with respective sequences of FSP27 (amino acids 137–173 and 174–200) and 38% and 48% similarities with Cidea (amino acids 122–158 and 159–185).
