Nucleolin, a Novel Partner for the Myb Transcription Factor Family That Regulates Their Activity

Abstract excerpt

To unravel the mechanisms of action of transcriptional regulation by the Myb family of transcription factors, we have set out to isolate their protein partners. We identify nucleolin as one of the nuclear polypeptides that interact specifically with the A-Myb and c-Myb, but not B-Myb DNA-binding domains. We show unambiguously that this interaction is direct and takes place in vivo, as demonstrated by...
