Abstract
Alpha2-macroglobulin (a2-M) is a broad spectrum protease binding protein. It is known to bind i.e. α-thrombin (1), and activated protein C (APC) (2). The proteinases are physically trapped and thus their active sites are excluded from natural substrates. It has been suggested that a2-M may provide protection from thromboembolic events in antithrombin (AT) deficient children due to complex formation with free α-thrombin (3).
