Furthermore, we demonstrate that a CCAAT site located upstream of the PU.1 site between positions -70 and -54 is involved in positive-negative regulation of the GM-CSF receptor alpha promoter activity .
 DNA: CCAAT site; protein: GM-CSF; protein: PU.1; DNA: PU.1 site; DNA: GM-CSF receptor alpha promoter; protein: GM-CSF receptor alpha
