Description

Application

I-CBP112 has been used in cell culture and sample preparation,[1] to verify the acetylation of VPS34 (vacuolar protein sorting 34), by p300 at K29, K771 and K781[2] and to diminish synergistic gene expression.[3]

Biochem/physiol Actions

I-CBP112 is a selective inhibitor of the bromodomain-containing transcription factors CREBBP (CBP) and EP300 (IC₅₀ = 0.142 and 0.625 μM, respectively). I-CBP112 has little activity against other bromodomains at concentrations up to 1 mM. For full characterization details, please see I-CBP112 on the Structural Genomics Consortium (SGC) website.
