  • 機能
    Participates in at least several B-cell activation processes as well as of other cell types. It is a costimulator of DNA-synthesis. It induces the expression of class II MHC molecules on resting B-cells. It enhances both secretion and cell surface expression of IgE and IgG1. It also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes.
  • 関連疾患
    Genetic variations in IL4 may be a cause of susceptibility to ischemic stroke (ISCHSTR) [MIM:601367]; also known as cerebrovascular accident or cerebral infarction. A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. Ischemic strokes, resulting from vascular occlusion, is considered to be a highly complex disease consisting of a group of heterogeneous disorders with multiple genetic and environmental risk factors.
  • 配列類似性
    Belongs to the IL-4/IL-13 family.
  • 細胞内局在
    Secreted.
  • Information by UniProt

レビューと Q&A

Thank you for contacting us. The ED50 is an expression of activity at 50% of its maximum response. Specific activity is just another way of conveying the activity of the protein. To calculate a specific activity, divide 1 x 106 by the ED50 in ng/ml...
