The present invention relates to methods of screening libraries of chimeric molecules comprising ribotoxic polypeptides, where screening is based on the interim reduction or elimination of ribotoxicity and the methods can identify cytotoxic molecules, each comprising a binding region and a ribotoxic region which jointly possess a desired assay-selectable characteristic, such as, e.g., binding to a target biomolecule, binding to a target cell, and/or cellular internalization.
