The EF-1 alpha gene encoding elongation factor-1 alpha is an enzyme which catalyzes the GTP-dependent binding of aminoacyl-tRNA to ribosomes.
EF-1α is one of the most abundant proteins in eukaryotic cells and is expressed in almost all kinds of mammalian cells. The promoter of this ’housekeeping’ gene exhibits a strong activity, higher than viral promoters such as SV40 and RSV promoters [1] and, on the contrary to the CMV promoter, yields persistent expression of the transgene in vivo [2]. InvivoGen has cloned the EF-1α promoter region of different species, among them the chimpanzee and rat. These sequences have not been described yet. They share respectively 98.46, 47.73 and 45.05% homology with the sequence of the human EF-1α promoter.
