The present invention relates to a method for producing an interleukin-2 protein using methylotrophic yeast. The method for producing interleukin-2 according to the present invention shows high cell growth and protein synthesis rates by use of the established optimal cell line, and produces a large amount of a protein comprising interleukin-2 by use of the established optimal culture conditions utilizing methanol that is an inexpensive carbon source. In addition, the method according to the present invention isolates and purifies the protein by a simple process. Accordingly, the method according to the present invention highly pure interleukin-2, and thus has a significant effect on the mass-production of interleukin-2.

Method for producing interleukin-2 protein using methylotrophic yeast

The present invention relates to an interleukin-2 expression construct for yeast, comprising a methanol oxidase (MOX) promoter; a human serum albumin gene or a fragment thereof; and an interleukin-2 (IL-2) gene, and to a yeast comprising the expression construct. The interleukin-2 expression construct for yeast according to the present invention makes it possible to produce an expressed and secreted fusion protein of human serum albumin (HSA) and interleukin-2 at low costs and easily separate recombinant interleukin-2 from the fusion protein. Thus, the interleukin-2 expression construct for yeast may be effectively used to produce a large amount of recombinant interleukin-2 with high purity.
