Here we demonstrate that both in vitro-translated PU.1 and PU.1 from nuclear extracts bind to a specific site in the M-CSF receptor promoter just upstream from the major transcription initiation site .
 ( protein: M-CSF receptor, None) , ( DNA: major transcription initiation site, None) , ( protein: PU.1, None) , ( protein: PU.1, None) , ( protein: vitro-translated PU.1, None) , ( protein: M-CSF, None) , ( DNA: M-CSF receptor promoter, None)
