Biochem/physiol Actions

TP-472 is a selective probe for bromodomain-containing proteins BRD9 and BRD7. This BRD9/7 probe was developed out of a collaborative effort by Takeda and the SGC, and is of a different chemotype from BRD9/7 probes previously available. TP-472 has a KD value of 33nM for BRD9 and 340nM for BRD7 by ITC. It is >30 fold selective for BRD9 over all other bromodomain family members except BRD7. It is suitable for in vivo applications. For full characterization details, please visit the TP-472 probe summary on the Structural Genomics Consortium (SGC) website.

TP-472N is used as a negative control and is available from Sigma. To learn more about and purchase TP-472N, click here.
