A complementary DNA analysis of the protein has revealed extensive amino-acid sequence homology to the products of a set of genes recently identified in organisms as diverse as Escherichia coli and man, which include the eukaryotic translation initiation factor elF-4A. The protein products of the new gene family have several motifs in common which are thought to be involved in nucleic acid unwinding. As yet, however, only elF-4A, through its effect on RNA, has been shown to possess unwinding activity. Here we report that purified p68 also exhibits RNA-dependent ATPase activity and functions as an RNA helicase in vitro. The protein was first identified by its specific immunological cross reaction with the simian virus 40 large T antigen, the transforming protein of a small DNA tumour virus. Surprisingly, T antigen also has an RNA-unwinding activity: the homology between the two polypeptides, although confined to only a small region resembling the epitope of the cross-reacting antibody (PAb204), should therefore be of functional significance. Furthermore, the RNA-unwinding activity may be involved in the growth-regulating functions of both proteins.</dcterms:abstract> <dc:contributor>Scheffner, Martin</dc:contributor> <bibo:uri rdf:resource=""/> <dc:creator>Scheffner, Martin</dc:creator> </rdf:Description> </rdf:RDF>
