In the early stages of the alternative pathway of complement activation there are complement control proteins that are soluble (factors H and I) and associated with the cell surface (DAF and MCP)

Identify the (i) soluble and (ii) cell surface-associated complement control proteins that operate in the terminal stages of the alternative pathway of complement activation, and describe their activities.

What will be an ideal response?


i. The soluble proteins include S protein, clusterin, and factor J, which all inhibit C5b, C6, and C7 from binding to cell membranes.
ii. The cell surface-associated proteins include homologous restriction factor (HRF) and CD59 (protectin), which both prevent the recruitment of C9 and thus block C9 polymerization.
