Protein Structure
UniProt Annotation
Function Plays an important role in the formation of pulmonary surfactant, probably by transporting lipids such as cholesterol.
Subcellular Localization Membrane {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}.
Disease Associations Pulmonary surfactant metabolism dysfunction 3 (SMDP3) [MIM:610921]: A rare lung disorder due to impaired surfactant homeostasis. It is characterized by alveolar filling with floccular material that stains positive using the periodic acid- Schiff method and is derived from surfactant phospholipids and protein components. Excessive lipoproteins accumulation in the alveoli results in severe respiratory distress. {ECO:0000269PubMed:15044640}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Highly expressed in lung, followed by brain, pancreas, skeletal muscle and heart. Weakly expressed in placenta, kidney and liver. Also expressed in medullary thyroid carcinoma cells (MTC) and in C-cell carcinoma.
