== Disease ==
[https://www.uniprot.org/uniprot/PROP_HUMAN PROP_HUMAN] Defects in CFP are the cause of properdin deficiency (PFD) [MIM:[https://omim.org/entry/312060 312060]. PFD results in higher susceptibility to bacterial infections; especially to meningococcal infections. Three phenotypes have been reported: complete deficiency (type I), incomplete deficiency (type II), and dysfunction of properdin (type III).<ref>PMID:8871668</ref> <ref>PMID:9710744</ref> <ref>PMID:10909851</ref> 
== Function ==
[https://www.uniprot.org/uniprot/PROP_HUMAN PROP_HUMAN] A positive regulator of the alternate pathway of complement. It binds to and stabilizes the C3- and C5-convertase enzyme complexes.
