Formation of transmembrane tubules by spontaneous polymerization of the hydrophilic complement protein C9.

Abstract

The ninth component of complement C9 can undergo circular polymerization in the fluid phase and on lipid membranes. The concomitant hydrophilic-amphiphilic transition is the result of a conformational reorganization of C9 and allows insertion of poly C9 into membranes in the form of a transmembrane protein channel. The ultrastructure of poly C9 resembles that of membrane lesions caused by complement.
