  • Target

    • Function

      Potent inhibitor of the complement membrane attack complex (MAC) action. Acts by binding to the C8 and/or C9 complements of the assembling MAC, thereby preventing incorporation of the multiple copies of C9 required for complete formation of the osmolytic pore. This inhibitor appears to be species-specific. Involved in signal transduction for T-cell activation complexed to a protein tyrosine kinase.
      The soluble form from urine retains its specific complement binding activity, but exhibits greatly reduced ability to inhibit MAC assembly on cell membranes.
    • Involvement in disease

      Defects in CD59 are the cause of CD59 deficiency (CD59D) [MIM:612300].
    • Sequence similarities

      Contains 1 UPAR/Ly6 domain.
    • Post-translational

      N- and O-glycosylated. The N-glycosylation mainly consists of a family of biantennary complex-type structures with and without lactosamine extensions and outer arm fucose residues. Also significant amounts of triantennary complexes (22%). Variable sialylation also present in the Asn-43 oligosaccharide. The predominant O-glycans are mono-sialylated forms of the disaccharide, Gal-beta-1,3GalNAc, and their sites of attachment are probably on Thr-76 and Thr-77. The GPI-anchor of soluble urinary CD59 has no inositol-associated phospholipid, but is composed of seven different GPI-anchor variants of one or more monosaccharide units. Major variants contain sialic acid, mannose and glucosamine Sialic acid linked to an N-acetylhexosamine-galactose arm is present in two variants.
      Glycated. Glycation is found in diabetic subjects, but only at minimal levels in nondiabetic subjects. Glycated CD59 lacks MAC-inhibitory function and confers to vascular complications of diabetes.
    • Cellular localization

      Cell membrane. Secreted. Soluble form found in a number of tissues.

    • Lane 1: Wild-type HAP1 whole cell lysate (40 µg)
      Lane 2: CD59 knockout HAP1 whole cell lysate (40 µg)

      Lanes 1 - 2: Merged signal (red and green). Green - ab133707 observed at 14 kDa. Red - loading control, ab9484, observed at 37 kDa.

      ab133707 was shown to specifically react with CD59 in wild-type HAP1 cells as signal was lost in CD59 knockout cells. Wild-type and CD59 knockout samples were subjected to SDS-PAGE. Ab133707 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
