Background: SFTPA1

Surfactant protein A is a protein with two isoforms, with lengths of 248 and 263 amino acids and weights of approximately 26 and 28 kDa respectively. Surfactant protein A binds to surfactant phospholipids in the presence of calcium ions and helps lower the surface tension in the alveoli of the lungs. Current research is being done on several diseases and disorders linked to this protein including pulmonary fibrosis, allergic bronchopulmonary aspergillosis, pulmonary alveolar proteinosis, non-small cell lung carcinoma, sclerosing hemangioma, otitis media, chronic obstructive pulmonary disease, bronchitis obliterans, bronchopulmonary dysplasia, rhinitis, aspergillosis, pulmonary edema, insulin resistance, and pneumoconiosis. Surfactant protein A has also been shown to have interactions with DMBT1, MYO18A, C1QA, SFTPD, and TLR2 in pathways such as the immune response, bacterial infections in CF airways, cell-cell communication, phagosome, and pertussis pathways.
