Methods and compositions for expression of competent eukaryotic gene products

DETAILED DESCRIPTION DNA constructions are provided comprising control elements derived from heat-shock genes associated with genes of interest, which permit the expression of the gene of interest in both procaryotic and eucaryotic cells.
In particular, for the efficient synthesis of fully competent gene products, a homologous combination of expression unit and host cell for expression is used and the nature of this homologous system is that of the same or similar cell type or organism that normally produces the said gene product.
