Description: CTPB is a potent activator of p300 activity, but not of PCAF (p300/CBP-associated factor). This compound has been shown to enhance p300 HAT-dependent transcriptional activation from in vitro assembled chromatin template. CTPB has also been noted to be a membrane-impermeable molecule that requires a carrier to move across the membrane barrier of cells.
