In the present study we have performed electrophoretic mobility-shift assays to investigate the pattern of protein binding to a 150 bp fragment of the proximal 5'-flanking region of the human monoamine oxidase B gene .
 ( DNA: proximal 5#$%#-flanking region, None) , ( protein: monoamine oxidase B, None) , ( DNA: 150 bp fragment, None) , ( DNA: human monoamine oxidase B gene, None)
