PFI-4 Chemical Properties, Uses, Production

Description

PFI 4 is an SGC chemical probe for the bromodomains of the BRPF (BRomodomain and PHD Finger containing) scaffolding protein BRPF1B. PFI 4 specifically binds to BRPF1B with an IC50 = 172 nM and Kd =13 nM as determined by ITC. PFI 4 reduces recovery time in triple BRD cell construct in FRAP and is potent in cells with IC50 250nM, while showing no effect on BRPF1A. PFI 4 exhibits >100-fold selectivity for BRPF1 over a panel of other bromodomains including BRPF2 (BRD1), BRPF3 and BRD4.

Uses

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.

Biological Activity

pfi 4 is a cell permeable, potent and selective inhibitor of brpf1 bromodomain with pic50 and pkd values of 7.1 and 8.0 [1].the brpf (bromodomain and phd finger-containing) family brpf1, brpf2/brd1, and brpf3 operate as scaffolds to assemble myst-family histone acetyltransferases (hats) complexes. brpf1 is a component of complexes containing the moz/morf transcriptional coactivators and links the catalytic hats to the other subunits ing5 and heaf6.8. brpf1 is important for maintaining skeletal development and hox gene expression in fish [1].in the bromoscan panel of 35 bromodomain binding assays, pfi 4 exhibited excellent brpf1 potency with pkd value of 8.0 and excellent selectivity over other bromodomains. in a cellular protein interaction assay, pfi 4 displaced nanoluc-tagged brpf1 bromodomain from halotaggedhistone h3.3 and disrupted chromatin binding [1].

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.
