Crystal structure of human CD59Crystal structure of human CD59
DiseaseDisease
[CD59_HUMAN] Defects in CD59 are the cause of CD59 deficiency (CD59D) [MIM:612300].[1]
FunctionFunction
[CD59_HUMAN] 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.
