Abstract
A polypeptide having gamma-interferon activity which lacks the amino acid sequence coded for by exon 4, a polynucleotide sequence which codes for said polypeptide, a replicable expression vehicle containing said polynucleotide sequence and a transformed microorganism containing said replicable expression vehicle are disclosed. The transformed microorganism is useful for preparing the polypeptide having gamma-interferon activity.
