Abstract
Expression of an endogenous gene is activated or increased following integration into the cell, by non-homologous or illegitimate recombination, of a regulatory sequence that activates expression of the gene. The invention also provides methods for the identification, activation, isolation, and/or expression of genes undiscoverable by current methods since no target sequence is necessary for integration. The invention also provides methods for the isolation of nucleic acid molecules (particularly cDNA molecules) encoding a variety of proteins, including transmembrane proteins, and for the isolation of cells expressing such transmembrane proteins which may be heterologous transmembrane proteins. Thus, by the present invention, endogenous genes, including those associated with human disease and development, may be activated and isolated without prior knowledge of the sequence, structure, function, or expression profile of the genes.
