This domain is found at the C-terminal end of human Properdin (CFP, for Complement factor P) and similar animal proteins. 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].	Domain
