Bractoppin is a potent, small-molecule chemical inhibitor that specific selectively blocks phosphopeptide recognition by the BRCA1 tBRCT domain with binding IC50 of 74 nM.
Bractoppin shows no inhibition for recognition of cognate biotinylated phosphopeptides to the TOPBP1 tBRCT 7/8, or GRB2 SH2 proteins.
Bractoppin engages BRCA1 tBRCT residues recognizing pSer in the consensus motif, pSer-Pro-Thr-Phe, plus an abutting hydrophobic pocket.
Bractoppin inhibits substrate recognition detected by Förster resonance energy transfer, and diminishes BRCA1 recruitment to DNA breaks, in turn suppressing damage-induced G2 arrest and assembly of the recombinase, RAD51.
Bractoppin selectively interrupts BRCA1 tBRCT-dependent signals evoked by DNA damage.
