Symbol | Description | Expression & Subcellular Location | Function | Disease |
---|---|---|---|---|
Elovl1 | Elongation of very long chain fatty acid protein1 | Expressed in lung type II cells. Endoplasmic Reticulum Membrane | Tissue-specific synthesis of very long fatty acids and sphingolipids. May catalyze the conversion of beta-ketoacyl CoA to beta-hydroxyacyl CoA or Reduction of trans-2-enoyl CoA to the saturated acyl CoA derivative. | Parkinson's disease |
Slc34a2 | Solute carrier family 34 (sodium phosphate), Member 2 | Apical Membrane of Type II cells | Actively transporting phosphate into cells via Na+ cotransport. May have a role in the synthesis of surfactant in lungs' alveoli. | pulmonary alveolar microlithiasis, ovarian cancer |
Soat1 (Acat) | Sterol O-acyltransferase 1 | Expressed in lung type II cells. Endoplasmic Reticulum Membrane | Catylyzes the formation of fatty acid-cholesterol esters. Plays a role in lipoprotein assembly and dietary cholesterol absorption. | atherosclerosis |
Zdhhc3 (Godz) | Palmitoyltransferase Zinc finger DHHC domain-containing protein 3 | Expressed in lung type II cells. Golgi apparatus | Palmitoyltransferase with broad specificity; membrane protein trafficking | Â |
Lpcat1 (Atyl2) | Acyltransferase-like 2 Phosphonoformate immuno-associated protein 3 | Expressed in lung type II cells. Endoplasmic Reticulum and Golgi Apparatus Membrane | Mediates the conversion of 1-acyl-sn-glycero-3-phosphocholine (LPC) into phosphatidylcholine (PC). May synthesize phosphatidylcholine in pulmonary surfactant, play a pivotal role in respiratory physiology. | migraines |
Stard4 | START domain-containing protein 4 | Expressed in lung type II cells. Mitochondria. | May be involved in the intracellular transport of sterols or other lipids. May bind cholesterol or other sterols | Huntington's disease |
Dlk1 (DLK) | Protein delta homolog 1 | Expressed in lung type II cells. Membrane | May function in adipocyte differentiation and in neuroendocrine differentiation | lung cancer, bronchiolo-alveolar adenocarcinoma, blepharophimosis, obesity, neoplasia, hypertriglyceridemia |
Prdx6 | Peroxiredoxin 6 | Expressed in lung type II cells. Cytoplasm, Lysosome, lung secretory organelles. | Involved in redox regulation of the cell. Can reduce H(2)O(2) and short chain organic, fatty acid, and phospholipid hydroperoxides. May play a role in the regulation of phospholipid turnover as well as in protection against oxidative injury | acute allergic pulmonary eosinophilia, asthma, follicular adenoma, Huntington's disease, neoplasia |
Abca3 | ATP-binding cassette, sub-family A (ABC1), member 3 | Expressed in lung type II cells. Membrane | Plays an important role in the formation of pulmonary surfactant, probably by transporting lipids such as cholesterol | surfactant metabolism dysfunction, inflation, respiratory failure, atelectasis |
