Background

FHR4 (Complement factor H-related protein 4; also FHR4B and CFHR4) is a 45 kDa glycoprotein member of the factor H-related protein family. It is synthesized by hepatocytes and circulates in plasma. FHR4(B) binds to C3b and C3d. It also binds to native (pentameric) C-reactive protein (pCRP), and is suggested to promote pCRP binding to necrotic cells surfaces, thus promoting cell clearance. Mature human CFHR is 312 amino acids (aa) in length. It contains five Sushi/SCR domains, the first of which (aa 23-85) is associated with pCRP binding. There is a circulating, 86 kDa alternative splice form termed FHR4A that shows an insertion of 247 aa after Asp92. This is considered the dominant isoform, and appears to show the same activity as CFHR. Over aa 41-331, human CFHR shares 61% aa identity with a related molecule found in rat.
