DNA fragment, recombination vector containing the same, and method of the expression of alien gene with the use of the same

摘要

A novel DNA which has a sequence different from those of publicly known DNAs capable of promoting the expression of an alien gene and can remarkably promote the expression of an alien gene. An isolated DNA fragment having a base sequence represented by SEQ ID NO:1 in the Sequence Listing; and an isolated DNA fragment represented by this base sequence wherein one or more nucleotides have been added, inserted, deleted or replaced and having the effect of promoting the expression of a gene located in the downstream thereof.
