Abstract: Disclosed is a gene therapy vector in which the occurrence of recombination is minimized. In order to minimize the occurrence of recombination, which is a major problem in the production and infection of a retroviral vector virus that continuously expresses a therapeutic gene during virus replication, a cleaved MCMV promoter was prepared by cutting the MCMV promoter on the basis of a repeat sequence, and the cleaved MCMV promoter was introduced to prepare a vector. It was confirmed that the vector having the cleaved MCMV promoter incorporated therein does not cause recombinations even after being incubated multiple times, and shows a continuous expression of the therapeutic protein, and in cells transfected with the virus containing the vector, cell death effectively occurs when a prodrug is administered thereto. Accordingly, the vector with minimized recombination occurrence of the present invention can be advantageously used for the treatment of cancer.
