title: [Hepatocyte receptors for proteinase inhibitor complexes with plasmin].
abstract: Hepatocyte receptors have been found for such complexes as alpha 2-macroglobulin-plasmin, pregnancy-associated plasma protein A-plasmin, and pregnancy-associated alpha 2-glycoprotein-plasmin, molecular masses of these receptors being estimated. The proteinaceous component of hepatocyte membranes contains heavy chains of plasmin and a 50 kDa fragment of plasmin molecule. These chains and the fragment are able to bind the native alpha 2-antiplasmin. Using immunoblotting no hepatocyte receptors for native macroglobulins, and alpha 2-antiplasmin-plasmin, alpha 1-proteinase inhibitor were detected.
