CFHR1 (Complement factor H-related protein 1) is a secreted glycoprotein with 5 conserved Sushi (CCP/SCR) domains in the extracellular region. Sushi is a motif of ~60 amino acids characterized by a framework of 4 conserved half-cystine residues (1-3 and 2-4 disulfide-bonded) and several other highly conserved residues including proline, tryptophan, tyrosine/phenylalanine and cysteine. This type of structure, also designated SCR (Short Consensus Repeat), is predominantly present in proteins associated with the complement system. CFHR1 is also a member of the complement factor H (CFH) gene family, and encodes one of the 5 CFH-related (CFHR) proteins. These 5 genes are closely linked to the CFH gene on chromosome 1q31-q32. The CFHRs are secreted plasma proteins synthesized primarily by the liver and composed of highly-related SCRs. CFHR1 may be involved in complement regulation. The dimerized forms of CFHR1 have avidity for tissue-bound complement fragments and efficiently compete with the physiological complement inhibitor CFH. CFHR1 can associate with lipoproteins and may play a role in lipid metabolism.  CFHR1 binds to Pseudomonas aeruginosa elongation factor Tuf together with plasminogen, which is proteolytically activated. Tuf may act as a virulence factor by acquiring host proteins to the pathogen surface, controlling complement, and facilitating tissue invasion. Mutations in the CFHR1 gene are associated with an increased risk of atypical hemolytic-uremic syndrome.

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
