Abstract: A transgenic rat containing in its genome a nucleotide sequence encoding a Ga subunit protein, which Ga protein subunit is uncoupled from regulation by Regulators of G-Protein Signaling (RGS) proteins, which Gx subunit protein is eventually the dominant-negative G188S mutant of Gax9, which nucleotide sequence is operatively associated with a neuron-specific expression control sequence, wherein the transgenic rat expresses the GA subunit protein in neural cells resulting in extended D-protein coupled receptor signaling mediated by the Ga subunit protein.

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.
