摘要
The interaction of the N-type calcium channel beta 3 subunit with the alpha 1B subunit alters the activation/inactivation kinetics and the maximal conductance of the channel. The defined protein-protein interaction of the human alpha 1B and beta 3 subunits provides a target for small-molecule modulation of N-type channel activity. We describe a high throughput screen based on a counterselection yeast two-hybrid assay, which was used to identify small molecules that disrupt alpha 1B-beta 3 subunit interactions and Inhibit N-type calcium channel activity. These small molecules may be a new class of calcium channel antagonists with therapeutic potential.
