Poly(A) polymerase purified from HeLa cell nuclear extract is required for both cleavage and polyadenylation of pre-mRNA in vitro.
We have partially purified a poly(A) polymerase (PAP) from HeLa cell nuclear extract which is involved in the 3'-end formation of polyadenylated mRNA. PAP had a molecular weight of approximately 50 to 60 kilodaltons. In the presence of manganese ions, PAP was able to polyadenylate RNA nonspecif...
