Description: | MS31 is a potent, highly affinity and selective fragment-like methyllysine reader protein spindlin 1 (SPIN1) inhibitor. MS31 potently inhibits the interactions between SPIN1 and H3K4me3 (IC50=77 nM, AlphaLISA; 243 nM, FP). MS31 selectively binds Tudor domain II of SPIN1 (Kd=91 nM). MS31 potently inhibits binding of trimethyllysine-containing peptides to SPIN1. MS31 is not toxic to nontumorigenic cells[1]. |
