Soluble Membrane Attack Complex: Biochemistry and Immunobiology

• Jerry Martin

The soluble membrane assault complicated (sMAC, a.ok.a., sC5b-9 or TCC) is generated on activation of complement and incorporates the complement proteins C5b, C6, C7, C8, C9 along with the regulatory proteins clusterin and/or vitronectin. sMAC is a member of the MACPF/cholesterol-dependent-cytolysin superfamily of pore-forming molecules that insert into lipid bilayers and disrupt mobile integrity and…
