Membrane cofactor protein (MCP; CD46). Isoforms differ in protection against the classical pathway of complement
1 Jun 1996
Abstract excerpt
Membrane cofactor protein (MCP; CD46) is a widely distributed C3b/C4b-binding glycoprotein that inhibits complement activation on host cells. MCP is expressed primarily as four isoforms that arise by alternative splicing of a single gene. The differences reside in the domains for O-glycosylation and cytoplasmic tails. Tissue-specific expression of isoforms and the differential processing of precursors mediated by...
