Summaries for SFTPB Gene

Entrez Gene Summary for SFTPB Gene

  • This gene encodes the pulmonary-associated surfactant protein B (SPB), an amphipathic surfactant protein essential for lung function and homeostasis after birth. Pulmonary surfactant is a surface-active lipoprotein complex composed of 90% lipids and 10% proteins which include plasma proteins and apolipoproteins SPA, SPB, SPC and SPD. The surfactant is secreted by the alveolar cells of the lung and maintains the stability of pulmonary tissue by reducing the surface tension of fluids that coat the lung. The SPB enhances the rate of spreading and increases the stability of surfactant monolayers in vitro. Multiple mutations in this gene have been identified, which cause pulmonary surfactant metabolism dysfunction type 1, also called pulmonary alveolar proteinosis due to surfactant protein B deficiency, and are associated with fatal respiratory distress in the neonatal period. Alternatively spliced transcript variants encoding the same protein have been identified.[provided by RefSeq, Feb 2010]

GeneCards Summary for SFTPB Gene

SFTPB (Surfactant Protein B) is a Protein Coding gene. Diseases associated with SFTPB include Surfactant Metabolism Dysfunction, Pulmonary, 1 and Sftpb-Related Pulmonary Surfactant Metabolism Dysfunction. Among its related pathways are Diseases of metabolism and Defective CSF2RB causes pulmonary surfactant metabolism dysfunction 5 (SMDP5). An important paralog of this gene is PSAP.

UniProtKB/Swiss-Prot for SFTPB Gene

  • Pulmonary surfactant-associated proteins promote alveolar stability by lowering the surface tension at the air-liquid interface in the peripheral air spaces. SP-B increases the collapse pressure of palmitic acid to nearly 70 millinewtons per meter.

  • Pulmonary surfactant metabolism dysfunction 1 (SMDP1) [MIM:265120]: 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:0000269 PubMed:7491219}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Respiratory distress syndrome in premature infants (RDS) [MIM:267450]: A lung disease affecting usually premature newborn infants. It is characterized by deficient gas exchange, diffuse atelectasis, high-permeability lung edema and fibrin-rich alveolar deposits called hyaline membranes. {ECO:0000269 PubMed:11063734}. Note=Disease susceptibility may be associated with variations affecting the gene represented in this entry. A variation Ile to Thr at position 131 influences the association between specific alleles of SFTPA1 and respiratory distress syndrome in premature infants.
