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. Enhances the expression of MYO18A/SP-R210 on alveolar macrophages (By similarity). (Microbial infection) Recognition of M.tuberculosis by dendritic cells may occur partially via this molecule (PubMed:17158455, PubMed:21203928). Can recognize, bind, and opsonize pathogens to enhance their elimination by alveolar macrophages (PubMed:21123169). (Microbial infection) Binds M.pneumoniae CARDS toxin, serves as one receptor for this pathogen (PubMed:15845487, PubMed:25139904). When SFTPA1 is down-regulated by siRNA, less toxin binds to human cells and less vacuolization (a symptom of M.pneumoniae infection) is seen (PubMed:25139904).

Activity summary

SFTPA1 and SFTPA2 also known as surfactant protein A1 and A2 are essential components of the pulmonary surfactant system. SFTPA1 and SFTPA2 are glycoproteins with a molecular mass of approximately 26 kDa. These proteins are mainly expressed in the lung alveolar type II epithelial cells. They play a critical role in reducing surface tension in the alveoli preventing lung collapse during respiration. SFTPA1 and SFTPA2 bind to lipids within the surfactant helping to maintain its structure and function.

Biological function summary

SFTPA1 and SFTPA2 are involved in the immune defense mechanisms of the lungs. Both proteins are part of the collectin family and form higher-order oligomeric structures. As a component of the surfactant protein complex they enhance phagocytosis of pathogens by alveolar macrophages and neutralize pathogens directly. Additionally they modulate inflammatory responses in the lung therefore contributing to the protection of pulmonary tissues.

Pathways

SFTPA1 and SFTPA2 are integral to the innate immune response and lipid metabolism pathways in the lungs. They interact with toll-like receptors (TLRs) and other surfactant proteins like surfactant protein D (SFTPD) to activate signaling pathways that lead to inflammation control. SFTPA1 and SFTPA2 also influence surfactant homeostasis within the lung environment contributing to the maintenance of respiratory function.

Associated diseases and disorders

SFTPA1 and SFTPA2 relate closely to respiratory distress syndrome (RDS) and pulmonary alveolar proteinosis (PAP). Mutations in SFTPA1 and SFTPA2 genes can impair surfactant function which often results in RDS particularly in premature infants. Moreover alterations in these proteins can also contribute to PAP where abnormal surfactant accumulation occurs. Their interplay with proteins like surfactant protein B (SFTPB) further links them to these pulmonary disorders as these proteins work together to ensure proper surfactant functionality.
