List of interactors

Use the search utility to find the interactor you are looking for. By clicking the column headers the table will be sorted on that column. Use shift+click to sort on multiple columns. Default sorting is on number of experiments, number of unique methods and the number of publications, and alphabetical on standard name, in that order.
