Background
This gene encodes a lung surfactant protein that is a member of a subfamily of C-type lectins called collectins. The encoded protein binds specific carbohydrate moieties found on lipids and on the surface of microorganisms. This protein plays an essential role in surfactant homeostasis and in the defense against respiratory pathogens. Mutations in this gene are associated with idiopathic pulmonary fibrosis. Alternate splicing results in multiple transcript variants. [provided by RefSeq, May 2010],
Function
disease:Genetic variations in SFTPA1 are associated with respiratory distress syndrome in premature infants (RDS) [MIM:267450]; also known as RDS in prematurity. RDS in the newborn is the main cause of mortality and morbidity in premature infants. RDS is characterized by deficient gas exchange that is caused by diffuse atelectasis and high-permeability lung edema that results in fibrin-rich alveolar deposits called 'hyaline membranes'. The risk of bronchopulmonary dysplasia increases with the severity of RDS.,function:In presence of calcium ions, it binds to surfactant phospholipids and contributes to lower the surface tension at the air-liquid interface in the alveoli of the mammalian lung and is essential for normal respiration.,miscellaneous:Pulmonary surfactant consists of 90% lipid and 10% protein. There are 4 surfactant-associated proteins: 2 collagenous, carbohydrate-binding glyco
