RECOMBINANT TRANSFERRIN MUTANTS

摘要

The present invention provides a recombinant protein comprising the sequence of a transferrin mutant, wherein Ser415 is mutated to an amino acid which does not allow glycosylation at Asn413 and/or wherein Thr613 is mutated to an amino acid which does not allow glycosylation as Asn61 1. It also provides polynucleotides encoding the same and methods of making and using said recombinant protein.
