mRNA 5'-cap binding activity in purified influenza virus detected by simple, rapid assay.

mRNA 5'-cap binding activity in purified influenza virus detected by simple, rapid assay. H Kroath and A J Shatkin ABSTRACT Reovirus mRNA 5'-terminal caps were 3'-radiolabeled with pCp and as affinity probes for proteins with cap binding activity. A rapid, simple, and sensitive blot assay was devised that could detect cellular cap binding protein in a complex polypeptide mixture. By using this method, cap binding activity was found in detergent-treated influenza virus but not in reovirus or vaccinia virus. Preincubation of capped reovirus mRNA with purified cellular cap binding protein reduced its primer effect on influenza transcriptase, whereas priming by ApG was not affected. The results indicate that influenza transcriptase complexes include cap-recognizing proteins that are involved in the formation of chimeric mRNAs.
