PFI-4 Chemische Eigenschaften,Einsatz,Produktion Methoden
Verwenden
PFI-4 is a chemical probe that specifically binds to the bromodomain of BRPF1 inhibiting binding to tri-acetylated histone 4 affecting the development of multiple tissues axial skeleton and hematopoietic system.
Biochem/physiol Actions
PFI-4 is an SGC chemical probe for the bromodomains of the BRPF (BRomodomain and PHD Finger containing) scaffolding protein BRPF1B. The BRPF proteins (BRPF1/2/3) assemble histone acetyltransferase (HAT) complexes of the MYST transcriptional coactivator family members MOZ and MORF. The BRPF1 protein is the scaffold subunit of the MYST acetyltransferase complex, which plays a crucial roles in DNA repair, recombination and replication as well as transcription activation. Mutations in MOZ, MORF, and BRPF1 have all been associated with cancer. BRPF1 exists in 2 different isoforms: BRPF1A and BRPF1B. PFI-4 specifically binds to BRPF1B with a Kd =13 nM as determined by ITC. It reduces recovery time in triple BRD cell construct in FRAP and is potent in cells with IC50 250nM, while showing no effect on BRPF1A.
