Entrez Gene Summary for CFHR1 Gene

  • This gene encodes a secreted protein belonging to the complement factor H protein family. It binds to Pseudomonas aeruginosa elongation factor Tuf together with plasminogen, which is proteolytically activated. It is proposed that Tuf acts as a virulence factor by acquiring host proteins to the pathogen surface, controlling complement, and facilitating tissue invasion. Mutations in this gene are associated with an increased risk of atypical hemolytic-uremic syndrome. [provided by RefSeq, Oct 2009]

GeneCards Summary for CFHR1 Gene

CFHR1 (Complement Factor H-Related 1) is a Protein Coding gene. Diseases associated with CFHR1 include atypical hemolytic-uremic syndrome with anti-factor h antibodies and hemolytic uremic syndrome, atypical 1. An important paralog of this gene is F13B.

UniProtKB/Swiss-Prot for CFHR1 Gene

  • Involved in complement regulation. The dimerized forms have avidity for tissue-bound complement fragments and efficiently compete with the physiological complement inhibitor CFH. Can associate with lipoproteins and may play a role in lipid metabolism.
