Atypical hemolytic uremic syndrome (aHUS) is characterized by complement attack
against host cells due to mutations in complement proteins or autoantibodies
against complement factor H (CFH). It is unknown why nearly all patients with
autoimmune aHUS lack CFHR1 (CFH-related protein-1). These patients have
autoantibodies against CFH domains 19 and 20 (CFH19-20), which are nearly
identical to CFHR1 domains 4 and 5 (CFHR14-5). Here, binding site mapping of
autoantibodies from 17 patients using mutant CFH19-20 constructs revealed an
autoantibody epitope cluster within a loop on domain 20, next to the two buried
residues that are different in CFH19-20 and CFHR14-5. The crystal structure of
CFHR14-5 revealed a difference in conformation of the autoantigenic loop in the
C-terminal domains of CFH and CFHR1, explaining the variation in binding of
autoantibodies from some aHUS patients to CFH19-20 and CFHR14-5. The
autoantigenic loop on CFH seems to be generally flexible, as its conformation in
previously published structures of CFH19-20 bound to the microbial protein OspE
and a sialic acid glycan is somewhat altered. Cumulatively, our data suggest that
association of CFHR1 deficiency with autoimmune aHUS could be due to the
structural difference between CFHR1 and the autoantigenic CFH epitope, suggesting
a novel explanation for CFHR1 deficiency in the pathogenesis of autoimmune aHUS.
