Protein Structure
|
|
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.
