Lipid storage in fat tissue is important for energy homeostasis and cellular functions. Through RNAi screening inDrosophilafat body, we found that knockdown of aDrosophilaNAD kinase (NADK), which phosphorylates NAD to synthesize NADPde novo, causes lipid storage defects. NADK sustains lipogenesis by maintaining the pool of NADPH. Promoting NADPH production rescues the lipid storage defect in the fat body ofNADKRNAi animals. Furthermore, NADK and fatty acid synthase 1 (FASN1) regulate mitochondrial mass and function by altering the levels of acetyl-CoA and fatty acids. Reducing the level of acetyl-CoA or increasing the synthesis of cardiolipin (CL), a mitochondrion-specific phospholipid, partially rescues the mitochondrial defects ofNADKRNAi. Therefore, NADK- and FASN1-mediated fatty acid synthesis coordinates lipid storage and mitochondrial function.
