Abstract
The present invention provides a process and host cell for use in increasing the amount of a desired protein by a cell line. The process and the cell line use a first transcription unit containing a gene for a transactivator protein to control the transactivation of a second transcription unit such that the amount of the desired protein expression can be increased without adversely affecting the cell growth. Preferred transactivator proteins are derived from EIA.
