Mechanism Of Cadmium-Mediated Inhibition Of Msh2-Msh6 Function In Dna Mismatch Repair, Manju Hingorani Oct 2009

Mechanism Of Cadmium-Mediated Inhibition Of Msh2-Msh6 Function In Dna Mismatch Repair, Manju Hingorani

Manju Hingorani

The observation that Cadmium (Cd(2+)) inhibits Msh2-Msh6, which is responsible for identifying base pair mismatches and other discrepancies in DNA, has led to the proposal that selective targeting of this protein and consequent suppression of DNA repair or apoptosis promote the carcinogenic effects of the heavy metal toxin. It has been suggested that Cd(2+) binding to specific sites on Msh2-Msh6 blocks its DNA binding and ATPase activities. To investigate the mechanism of inhibition, we measured Cd(2+) binding to Msh2-Msh6, directly and by monitoring changes in protein structure and enzymatic activity. Global fitting of the data to a multiligand binding model …
