Abstract

Provided is a ramp tag capable of solving instability in translation rate resulting from poor compatibility between codons in a foreign gene and a host when expressing a recombinant protein in. Unlike the conventional codon optimization or codon deoptimization method for solving the problem of rare codons, the present invention increases an expression efficiency of a target protein by merely having the ramp tag be fused with a target gene or independently expressed, without changing the original codon sequence, thereby allowing tRNA to be reused. Thus, the present invention provides a novel method for increasing recombinant protein expression which is capable of reducing costs and time in comparison to the codon optimization method that artificially synthesizes DNA sequences. Therefore, it is expected that the method of the present invention will be able to be used in production of high value-added pharmaceuticals or industrial enzymes.
