Binding of NS1 to cleavage and host polyadenylation specificity factor (CPSF) GENE ONTOLOGYGO:0046778 Influenza virus's non-structural protein (NS1) binds to the host cell's cleavage and host polyadenylation specificity factor (CPSF), inhibiting the ability of CPSF to bind to pre-mRNAs and thus preventing efficient 3' end processing and export of host cell mRNAs out of the nucleus.
