EMSA showed that nuclear proteins from PC12 but not C6 or Rat2 cells bind the CRE as a complex containing activating transcription factor ( ATF ) - 4 and CCAAT enhancer - binding protein beta , while both PC12 and C6 cell nuclear extracts were recruited by the CCAAT - box as a complex containing nuclear factor Y .
 GENE: activating transcription factor ( ATF ) - 4; GENE: CCAAT enhancer - binding protein beta; GENE: nuclear factor Y
