Abstract
The 68k ankyrin-like protein (68k-ank) of unknown function is highly conserved among orthopoxviruses and contains ankyrin repeats and an F-box-like domain. We performed a yeast-two-hybrid screen with 68k-ank to find interacting proteins. From a human and a murine cDNA library, 99% of the interaction partners were S-phase kinase-associated protein 1a (Skp1a), a part of the SCF ubiquitin ligase complex. 68k-ank co-immunoprecipitated with components of the endogenous, mammalian SCF ubiquitin ligase. This interaction was F-box domain dependent and could also be observed in infected cells, indicating that SCF complex formation might be important for the viral life cycle.
