BLM inhibitor 2 is a specific inhibitor of BLM (Bloom syndrome protein) ATPase-coupled DNA helicase activity (IC50=2.2 uM) via the allosteric binding site.BLM inhibitor 2 displays high selectivity over members of the RecQ-helicase family in ATP-turnover assays, including recombinant helicase domains (HD) from human WRN, human RecQ5 or E. coli helicase UvrD, and human RecQ1.BLM inhibitor 2 is a non-competitive inhibitor, does not interfere with ATP-binding, unliker ML216.BLM inhibitor 2 inhibits production of the single-stranded DNA product in a dose-dependent manner (IC50=1.8 uM) via inhibition of the helicase activity of BLM-HD.BLM (Bloom syndrome protein) is a RECQ-family helicase involved in the dissolution of complex DNA structures and repair intermediates (BLM, WRN, RECQ1, RECQ4, and RECQ5 in humans).
