Random mutagenesis and screening of complex glycoproteins: expression of human gonadotropins in Dictyostelium discoideum [PDF]

, 1999
The soil amoeba Dictyostelium discoideum is a host cell that provides simple genetics in combination with complex protein synthesis. We show that the complex human heterodimeric gonadotropins can be produced and secreted by this organism.
