This transgene comprises the enhanced green fluorescent protein cDNA downstream of the "CAG promoter" - which consists of the cytomegalovirus immediate early (CMV-IE) enhancer followed by a 1.3-kb DNA segment including the promoter, first exon and first intron of the chicken beta-actin gene, with the 3'splice junction sequence replaced by that of the rabbit hemoglobin beta gene -- and followed by the bovine globin polyadenylation signal. In this line, fluorescence in situ hybridization showed that the transgene integrated into band C3 of the X Chromosome. (J:87415, J:110379, J:122541, J:126028)
