Multiple gene expression including sorf contructs and methods with polyproteins, pro-proteins, and proteolysis

摘要

Disclosed is an expression vector for expressing a recombinant protein, comprising a coding sequence for a polyprotein, wherein the polyprotein comprises at least a first and a second protein segment, wherein said protein segments are separated by a protein cleavage site therebetween, wherein the protein cleavage site comprises a self processing peptide cleavage sequence, a signal peptide cleavage sequence, or a protease cleavage sequence; and wherein said coding sequence is expressible in a host cell and is cleaved within the host cell.
