Background: HAI-1
Hepatocyte growth factor activator inhibitor-1 (HAI-1) encoded by the Spint1 gene is a Kunitz-type serine protease inhibitor, identified as a strong inhibitor of HGF activator (HGFA) and matripase (1). The membrane-anchored HAI-1 consists of two Kunitz domains, a LDL-receptor-like domain, and a C-terminal transmembrane domain (2). Two soluble forms are generated by ectodomain shedding, one with a single Kunitz domain and the other with two Kunitz domains. HAI-1 is not only an inhibitor but also a specific receptor of active HGFA, acting as a reservoir of this enzyme on the cell surface (3). The shedding of HAI-1 and HGFA/HAI-1 complex is enhanced by treatment with phorbol 12-myristate, 13-acetate or IL-1 beta. The regulated shedding is completely inhibited by a synthetic zinc metalloprotease inhibitor (3).
