DNA fragment elevating gene expression dose

摘要

A novel DNA fragment capable of enhancing the expression level of a gene. The DNA fragment according to the present invention contains a nucleotide sequence from one of the nucleotides at around positions 1- to 152 to one of the nucleotides at around positions 259 to 374 in the sequence represented by SEQ ID NO:1 and is capable of enhancing the expression level of a gene.
