We have isolated the 5' region of the ecto-5'-nucleotidase (low K(m) 5'-NT) gene and established that a 969-base pair (bp) fragment confers cell-specific expression of a CAT reporter gene that correlates with the expression of endogenous ecto-5'-NT mRNA and enzymatic activity .
 ( DNA: CAT reporter gene, None) , ( DNA: 969-base pair (bp) fragment, None) , ( DNA: 5#$%# region, None) , ( DNA: ecto-5#$%#-nucleotidase (low K(m) 5#$%#-NT) gene, None) , ( RNA: endogenous ecto-5#$%#-NT mRNA, None) , ( protein: ecto-5#$%#-nucleotidase, None)
