DNA FRAGMENT, RECOMBINANT VECTOR CONTAINING THE SAME AND METHOD FOR EXPRESSING FOREIGN GENES USING 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; a nd 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.
