Extra Details:: Inhibition of the nuclear export of poly(A)-containing mRNAs caused by the influenza A virus NS1 protein requires its effector domain. The NS1 effector domain functionally interacts with the cellular 30kD subunit of CPSF4 an essential component of the 3' end processing machinery of cellular pre-mRNAs. In influenza virus- infected cells, the NS1 protein is physically associated with cleavage and polyadenylation specific factor 4, 30kD subunit. Binding of the NS1 protein to the 30kD protein in vitro prevents CPSF binding to the RNA substrate and inhibits 3' end cleavage and polyadenylation of host pre-mRNAs. Source: Recombinant protein corresponding to human CPSF4, fused to His-tag at N-terminal expressed in E.coli.
