Target Details

  • Target: Complement component (3d/Epstein Barr virus) receptor 2 (CR2, CD21)
  • Tissue cell line specificity: Mouse
  • Target background: CR2 is expressed strongly on mature B cells, follicular dendritic cells and weakly on immature thymocytes and T lymphocytes. In B-cell ontogeny, CR2 appears after the pre-B-stage, is maintained during peripheral B-cell development and is lost upon terminal differentiation into plasma cells. CR2 expression is also gradually lost after stimulation of B cells in vitro. CR2 functions as a receptor for C3d, C3dg and iC3b Complement components and for EBV and for IFN alpha. CR2 binds to CD23 and as...
