RAD51-Stimulatory Compound-1, RS-1

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.

General description

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.This HDR (homology-directed repair) enhancer, is shown to significantly increase both Cas9 & TALEN-mediated knock-in efficiencies.

The mammalian germline is characterized by extensive epigenetic reprogramming during its development into functional eggs and sperm. Specifically, the epigenome requires resetting before parental marks can be established and transmitted to the next generation. In the female germline, X-chromosome inactivation
