It is a hydrophobic protein with an approximate mass of 8 kDa after processing from its precursor form which is larger. The protein is expressed predominantly in type II alveolar cells in the lungs and is found in lamellar bodies. SP-B functions mechanically by reducing surface tension in the alveoli facilitating efficient gaseous exchange and lung compliance.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nSP-B plays a significant role in the formation and stabilization of pulmonary surfactant film. It acts in conjunction with phospholipids to form a protein-lipid complex. This complex is critical for lowering surface tension at the air-liquid interface in the alveoli preventing lung collapse during exhalation. SP-B integrates lipid components into the surfactant matrix and enhances its spreading and surface activity.\u003cbr\u003e\nPathways\u003cbr\u003e\nSP-B serves an integral part in lung surfactant metabolism and the phospholipid metabolic pathway. These pathways ensure the homeostasis and turnover of surfactant materials. Proteins such as surfactant proteins A (SP-A) and C (SP-C) are also involved in these pathways coordinating with SP-B to maintain surfactant function and lung physiology. Together these proteins help maintain the balance necessary for proper respiratory mechanics.\u003cbr\u003e\nDeficiency or mutation in SP-B is associated with respiratory distress syndrome (RDS) and interstitial lung diseases. These conditions manifest due to compromised surfactant function leading to alveolar collapse. SP-B mutations can disrupt the normal surfactant pathway leading to insufficient lung function. Disorders like these often involve SP-C as well with both proteins affected in cases of congenital surfactant deficiency further impacting pulmonary health.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843904131241,"sku":"ab114372","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab114372","provider":"Iright","version":"1.0","type":"link"}
