Abstract

See full text

Methods of inserting genes into defined locations in the chromosomal DNA of cultured mammalian cell lines which are subject to gene amplification are disclosed. In particular, sequences of interest (e.g., genes encoding biotherapeutic proteins) are inserted proximal to selectable genes in amplifiable loci, and the transformed cells are subjected to selection to induce co-amplification of the selectable gene and the sequence of interest. The invention also relates to meganucleases, vectors and engineered cell lines necessary for performing the methods, to cell lines resulting from the application of the methods, and use of the cell lines to produce protein products of interest.
