Although sequences located between -559 and -88 of the zeta 2 globin gene were dispensable for its expression on enhancerless plasmids , they were required for the HS-40 enhancer -mediated activity of the zeta 2 globin promoter .
 DNA: zeta 2 globin promoter; DNA: HS-40 enhancer; DNA: enhancerless plasmids; DNA: zeta 2 globin gene; DNA: HS-40
