The modular structure of hepatocyte growth factor/scatter factor (HGF/SF) has facilitated structure-function analysis. Domain deletion experiments have established that the N-domain, kringle 1 and kringle 2 are essential for HGF/SF activity on target cells and that, conversely, truncated variants containing the N-domain and kringle 1 (NK1) or kringles 1 and 2 (NK2) exhibit partial agonistic or antagonistic activity depending on target cells and the presence of full length HGF/SF. The 3D structures of the six domains of HGF/SF have been modelled on the structure of homologues, offering interesting insights into putative mechanisms of domain interactions, receptor binding and activation. The predictions offered by such models are currently assessed by protein engineering techniques and will ultimately be measured against experimental structures.
