    basic FUNCTION
  • homologous restriction factor (18 kD) binding through C8G to the membrane attack complex of complement as a membrane inhibitor of cell lysis
  • functions as a co-receptor in natural killer cell activation
  • inhibits assembly of the lytic membrane attack complex of complement by incorporation into the forming complex
  • may inhibit the cytolytic activity of complement by binding to C8/C9 and protect host cell membranes against homologous membrane attack complex (MAC)
  • broadly expressed GPI-anchored molecule, regulates formation of the membrane attack complex of the complement cascade
  • CD55 inhibits the formation of C3 convertases, and CD59 prevents the terminal polymerisation of the membrane attack complex
  • CD55 and CD59 restrict complement activation by inhibiting C3/C5 convertases activities and membrane attack complex formation, respectively (
  • GPI-anchored membrane regulator of complement expressed on blood cells as well as peripheral tissues
    signaling signal transduction
    a component
    small molecule
  • membrane attack complex of complement
  • physically associated with NKP46 and NCR3
  • CD59 (complement defense 59) mRNA is a novel cleavage target of ERN1
  • cell & other T cell activation
    activated by HBXIP, that upregulates CD46, CD55 and CD59 through p-ERK1/2/NFKB signaling to protect breast cancer from complement-dependent cytotoxicity
