SOLUTION STRUCTURE OF TRIMERIC FORM OF PROPERDIN BY X-RAY SOLUTION SCATTERING AND ANALYTICAL ULTRACENTRIFUGATION

Template:ABSTRACT PUBMED 15491616

Disease

[PROP_HUMAN] Defects in CFP are the cause of properdin deficiency (PFD) [MIM: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).[1][2][3]

Function

[PROP_HUMAN] A positive regulator of the alternate pathway of complement. It binds to and stabilizes the C3- and C5-convertase enzyme complexes.

About this Structure
