Simian and human immunodeficiency virus type 1 (SIV and HIV-1) Nef proteins are thought to use different molecular surfaces to mediate the protein-protein interactions required for their otherwise similar functions. This genetically separable function suggests convergent evolution of primate lentiviruses and/or structural differences between human and nonhuman primate cellular target proteins. However, such comparative molecular analyses have not been undertaken so far using the respective natural host-derived cellular targets. We cloned simian Src family kinase Hck and analyzed structurally and biochemically its interaction with SIV Nef.
