Proacrosin, the zymogen precursor of acrosin, was shown to associate with anionic phospholipid membranes through apparent electrostatic charge interactions. This association was diminished by elevated cation concentrations and was dependent on membrane composition, as shown both by direct binding assays and by following the phospholipid stimulation of conversion of proacrosin into acrosin.

It has become clear that β2-glycoprotein I (β2GPI) is the most common and best-characterised antigenic target for ‘antiphospholipid’ (aPL) autoantibodies. These antibodies preferentially bind β2GPI that has been immobilised on anionic phospholipid membranes or certain synthetic surfaces. These surfaces appear to act by increasing antigen density to allow binding of intrinsically low-affinity anti-β2GPI autoantibodies. Binding of β2GPI in fluid phase is weak and requires high concentrations of β2GPI. Our understanding of the pathophysiology of the ‘Antiphospholipid’ Syndrome (APS) has increased exponentially with the number of studies into the interactions of aPL antibodies and β2GPI.
