Cloning and sequence determination of the Schizosaccharomyces pombe rpb2 gene encoding the subunit 2 of RNA polymerase II.

abstract：:Influenza A virus segment 2 mRNA expresses three polypeptides: PB1, PB1-F2 and PB1-N40, from AUGs 1, 4 and 5 respectively. Two short open reading frames (sORFs) initiated by AUGs 2 and 3 are also present. To understand translational regulation in this system, we systematically mutated AUGs 1-4 and monitored polypeptid...
