   3.4.21.46 | malfunction |
deficiency of factor D leads to exacerbated liver injury and inflammatory cells. The absence of Factor D and lack of C3b/iC3b/C3c deposition following CCl4-induced injury is associated with more severe and prolonged liver injury |

| 3.4.21.46 | malfunction |
knockdown of complement factor D in senescent fibroblasts significantly reduces the increase of matrix metalloproteinase 1 in the co-cultured young fibroblasts |

| 3.4.21.46 | metabolism |
in humans neither MASP-1 nor MASP-3 are required for alternative pathway function. During MASP-1/-3 deficiency significant alternative pathway activity remains, indicating that mature factor D is present in the absence of MASP-1/-3 |

the substrate-binding, or exosite, region displays a well defined and rigid conformation. A salt bridge between Arg202 on the self-inhibitory loop and Asp177 locks the S1 pocket and rigidifies the exosite. Asp-His-Ser catalytic site. The enzyme exhibits conformational dynamics like thrombin, but unlike in thrombin a mechanism has evolved in factor D that locks the unbound native state into an ordered inactive conformation via the self-inhibitory loop. The Asp-His-Ser catalytic site of the enzyme is in an enzymatically active conformation induced by substrate binding at the exosite |

| 3.4.21.46 | physiological function |
alternative complement pathway component Factor D contributes to efficient clearance of tissue debris following acute CCl4-induced injury in the liver. Acute toxic injury to the liver results in the death of hepatocytesby necrosis and apoptosis. If removal of damaged tissue is inadequate and injury persists, reorganization of the extracellular matrix is impaired |

| 3.4.21.46 | physiological function |
enzyme overexpression promotes adipocyte differentiation, increasesC3a production, and leads to induction of C3a receptor target gene expression |

| 3.4.21.46 | physiological function |
human factor D is a self-inhibited thrombin-like serine proteinase that is critical for amplification of the complement immune response |

| 3.4.21.46 | physiological function |
in total 150 gastric cancer patients who underwent radical gastrectomy are analyzed (75 cases presented with hepatic metastases and 75 cases presented without any recurrences). Significant association is shown between VEGF-D expression and hepatic metastasis from gastric cancer after radical gastrectomy |
