IMPROVED PROTEIN PRODUCTION IN A HOST

摘要

Recombinant DNA constructs that provide for expression of desired target proteins as protein bodies in various host cells, tissues, and organisms are disclosed. Such recombinant DNA constructs contain a heterologous polynucleotide comprising an ER luminal folding chaperone interacting domain (CID), a sequence that codes for a trans-membrane domain (TMD); and a sequence that codes for a protein-protein interaction domain (PPID) that are operably linked to a sequence encoding the desired target protein. Proteins obtained from the constructs, host cells containing the constructs, and methods for obtaining desired target proteins encoded by the constructs are also disclosed.
