Hepatocyte growth factor activator inhibitor

From Proteopedia

Human hepatocyte growth factor activator inhibitor 1 Kunitz domain 1 (green) complex with HGFA (blue) and phosphate (PDB code 1yc0) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Function Hepatocyte growth factor activator inhibitor (HAI) or Kunitz-type protease inhibitor contains 2 Kunitz domains[1]. HAI-1 is a cell surface-binding protein and regulates hepatocyte growth factor activator activity in the pericellular microenvironment[2]. Relevance Abnormal levels of HAI-1 were observed in various types of human cancer[3]. Structural highlights in the manner of other trypsin-like proteases inhibitors[4].
