Evolutionary conservation of the lipopolysaccharide binding site of β2-glycoprotein I

Abstract excerpt

β₂-Glycoprotein I (β₂GPI) is a highly abundant plasma protein and the major antigen for autoantibodies in the antiphospholipid syndrome. Recently, we have described a novel function of β₂GPI as scavenger of lipopolysaccharide (LPS). With this in mind we investigated the conservation of β₂GPI in vertebrates and set out to identify the binding site of LPS within β₂GPI. The genome sequences of 42 species were...
