Gene control

摘要

The present invention relates to a recombinant genetic material which can be operably linked to protein encoding sequence comprising an expression control sequence having at least one promoter region and at least one repressor region such that basal expression in a tissue where the protein is required to be expressed is reduced whilst allowing induction of expression of the protein encoding sequence. Suitably the promoter is a p450 type promoter whilst suitably it is the p450 CYP1A1 promoter of the rat. The invention further provides a method of manufacturing proteins for polypeptides in the method of manufacturing or recombinant construct for transgene induction.
