abstract：:ABCA3 mutations cause fatal surfactant deficiency and interstitial lung disease. ABCA3 protein is a lipid transporter indispensible for surfactant biogenesis and storage in lamellar bodies (LB). The protein folds in endoplasmic reticulum and is glycosylated in Golgi en route to the membrane of mature LB and their prec...
