Novel proteins possessing substantially the same biological activity as human GM-CSF, as well as proteins having a higher specific activity than native human GM-CSF, are disclosed. The proteins may (a) be unglycosylated; (b) lack N-linked glycosylation but have O-linked glycosylation; or (c) lack one of the two N-linked carbohydrate chains characteristic of native human GM-CSF. The proteins are produced using recombinant DNA techniques in eucaryotic host cells, such as mammalian, yeast, and filamentous fungal host cells. Pharmaceutical compositions including an effective amount of one of the proteins of the invention and a physiologically acceptable carrier or diluent are also disclosed.
