Lipid droplet-associated protein which plays a role in lipid droplet clustering (PubMed:26121959, PubMed:26025681, PubMed:26357594). Expressed in intestinal and epidermal cells (PubMed:26357594). Expressed in the muscle and hypodermis (PubMed:26025681). Expressed from embryos to adults (PubMed:26357594). First expressed at the 3-fold stage of embryonic development (PubMed:26357594). Highly expressed in embryos (PubMed:26025681). Viable, and able to reproduce normally, but embryos contain large lipid droplets (PubMed:26121959, PubMed:26357594). Reduced body fat accumulation (PubMed:26121959). Lipid droplets cluster in intestinal cells and contain a reduced amount of triglycerides (PubMed:26025681). RNAi-mediated knockdown results in a reduced brood size (PubMed:26357594). Belongs to the perilipin family.
