CFP is a positive regulator of the alternate pathway (AP) of complement. It contains six thrombospondin repeat type I (TSP 1-6 domains and an N-terminal domain (Pfam:PF18487). This entry represents the last TSP type I domain, which binds to the first TSP type I domain (Pfam:PF00090), contributing to multimerisation [1-5].

Subsequently, many additional members of the family were identified on the basis of sequence similarity between the C-terminal domains of netrins, complement proteins C3, C4, C5, secreted frizzled-related proteins, and type I pro-collagen C-proteinase enhancer proteins (PCOLCEs), which are homologous with the N-terminal domains of tissue inhibitors of metalloproteinases (TIMPs). The TIMPs are classified as a separate family in Pfam (Pfam:PF00965) [2]. This expanded domain family has been named as the NTR module [2].
