In particular, Western , supershift , and promoter deletion analyses suggested a role for CCAAT/enhancer-binding protein-beta ( C/EBP-beta ) binding site between -2010 and -1954 in regulating transcription of collagenase-1 in monocytic cells .
 ( protein: collagenase-1, None) , ( protein: CCAAT/enhancer-binding protein-beta, None) , ( protein: C/EBP-beta, None) , ( DNA: -2010 and -1954, None) , ( cell type: monocytic cells, None) , ( DNA: CCAAT/enhancer-binding protein-beta ( C/EBP-beta ) binding site, None)
