A cell-permeable sulfonamido-benzamide-based allosteric regulator that stimulates DNA binding and recombinase activities of hRAD51 by locking hRAD51 in an active conformation without affecting its active site ATP hydrolysis. Although RS-1 enhances hRAD51 filament formation on ssDNA with or without the cofactor NTP, active filaments and recombinase activity are only induced in the presence of ATP or AMP-PNP, but not with ADP or no cofactors. Shown to promote resistance of primary human neonatal dermal fibroblasts to Cisplatin- (Cat. No.
232120) induced death in a dose-dependent manner. RS-1 is inactive toward related DNA strand exchange proteins scRAD5 and scDMC1 of yeast origin or
E. coli RedA.
