靶點(diǎn)詳情

  • 功能：
    Serum protease that plays an important role in the activation of the complement system via mannose-binding lectin. After activation by auto-catalytic cleavage it cleaves C2 and C4, leading to their activation and to the formation of C3 convertase.
  • 基因功能參考文獻(xiàn)：
    1. MASP-2 has an essential role in the mediation of cerebral ischemia-reperfusion injury. PMID: 27577570
    2. this study shows that MASP-2 contributes to the development of collagen Ab-induced arthritis PMID: 28739878
    3. We induced anti-myeloperoxidase vasculitis in mice and showed that neither MASP-2- nor properdin-deficient mice were protected, suggesting that alternative pathway activation does not require properdin or the lectin pathway. PMID: 27235854
    4. Mannan-binding lectin-associated serine protease 2 is critical for the development of renal ischemia reperfusion injury and mediates tissue injury in the absence of complement C4. PMID: 24868011
    5. Gene targeting of mouse TDP-43 negatively affects Masp2 expression. PMID: 24740308
    6. ALI in H5N1-infected mice was caused by excessive complement activation, as demonstrated by deposition of C3, C5b-9, and MBL-C in lung tissue, and by up-regulation of MBL-associated serine protease-2 and the complement receptors C3aR and C5aR. PMID: 23526211
    7. study corroborates the essential function of MASP-2 in the lectin pathway and highlights the importance of mannan-binding lectin-independent lectin pathway activation in the host defense against pneumococci PMID: 22792067
    8. Targeting of mannan-binding lectin-associated serine protease-2 confers protection from myocardial and gastrointestinal ischemia/reperfusion injury. PMID: 21502512
    9. Highly conserved intron sequences. Restricted expression contrasts with the ubiquitous expression of neighboring genes. PMID: 15672593
    10. Recombinant protein of masp2 was made and purified. PMID: 15826378
    11. MASP-2 is essential for the activation of C4 and sMAP plays a regulatory role in the activation of the lectin pathway. PMID: 17142762
