靶點詳情

  • 功能：
    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.
  • 基因功能參考文獻：
    1. SP-A expression was up-regulated in the middle ear effusion of non-typeable Haemophilus influenza otitis media. PMID: 30055742
    2. SPA binds dipalmitoyl-phosphatidylcholine, the major surfactant lipid component, but not phosphatidylinositol; SPD exhibits the opposite preference. Data suggest flexibility in a key surface loop supports distinctive lipid binding of SPA; quadruple mutant SPA (E171D/P175E/R197N/K203D) that introduces SPD-like loop-stabilizing Ca2+ binding site in carbohydrate recognition domain exhibits ligand-binding preferences of SPD.

    9. A novel role is demonstrated for SP-A in modulating endolysosomal trafficking via Rab7b (but not Rab5 nor Rab11) in primary alveolar macrophages, and the biochemical pathways are defined. PMID: 21248257
    10. SP-A stimulates the release of neutrophil chemotactic factor by alveolar type II cells, and this effect is mediated by the receptor for SP-A specifically expressed by these cells. PMID: 20473679
    11. VIP elevated SP-A expression in ATII cells which was mediated by enhanced sp-a gene transcription PMID: 20688121

    14. Data suggest that the pathway for secretion of newly synthesized surfactant protein-A is by transfer from the site of synthesis to the storage/secretory organelle prior to lamellar body exocytosis. PMID: 20382745
    15. the ability of SP-A to inhibit immune cell activation by Re-LPS may be due to its ability to block the binding of Re-LPS to LBP and prevent the initiation of the LBP/CD14 pathway for inflammatory reactions in the lung. PMID: 12204898
    16. SP-A selectively enhances mannose receptor expression on monocyte-derived macrophages, a process involving both the attached sugars and collagen-like domain of SP-A. PMID: 12244146
    17. SP-A can reverse the detrimental effects of surfactant oxidation on the biophysical properties of surfactant, by a mechanism that is dependent on interchain disulfide bond formation and the C-terminal domains of the protein. PMID: 12600986

    25. NO mediated the decrease in surfactant protein gene expression PMID: 15640287
    26. We suggest that enhanced release of surfactant phospholipids and SP-A represents an early protective response that compensates in part for the inactivation of intraalveolar surfactant in the early phase of IR injury. PMID: 15969762
    27. The addition of rat or recombinant rat SP-A to human monocyte-derived macrophages significantly raises the level of cytosolic calcium above baseline within 10 seconds of SP-A addition PMID: 16081790
    28. SP-A and Prdx6 directly interact, which provides a mechanism for regulation of the PLA(2) activity of Prdx6 by SP-A PMID: 16330552
    29. results indicated SP-A & SP-D have distinct functions in lung homeostasis & the function of the neck domain & carbohydrate recognition domain of SP-D is dependent on its own NH2-terminal & collagenous domains that cannot be complemented by those of SP-A PMID: 16500946
    30. Direct effect of SFTPA1 on rat myometrial cells and inhibitory cross talk between SFTPA1 and LPS signals. PMID: 17202387
    31. SP-A2 enhances phagocytosis of Pseudomonas aeruginosa by rat alveolar macrophages more than does SP-A1. PMID: 17220308
    32. Air spaces of neonatal lungs comprised lower fractions of tubular myelinand increased unilamellar vesicles, which correlated with low SP-A concentrations in lung lavage fluid and increased respiratory rates, respectively PMID: 17469149
