    摘要： The present invention provides a method for the identification of a pattern of changes in cellular responses induced by the selective inhibition of a signaling molecule, by determining the specific effects of a selective inhibitor on a mutant form of a signaling molecule on cellular responses. The pattern of alterations in cellular responses resulting from the inhibition by a selective mutant inhibitor of the mutant signaling molecule are characteristic of the cellular response alterations that a specific inhibitor of the wild-type signaling molecule will produce. After determining the pattern of cellular responses of the mutant cells with the mutant molecule, compounds may be identified capable of inhibiting the wild-type molecule by producing a pattern of cellular responses in wild-type cells matching or having similarity to that of the inhibition of the mutant molecule.

Modified nucleotide triphosphate substrates and methods of making and using them. Methods for using such engineered kinases and such modified substrates to identify which protein substrates the kinases act upon, to measure the extent of such action, and to determine if test compounds can modulate such action. Also engineered forms of multi-substrate enzymes which covalently attach part or all of at least one (donor) substrate to at least one other (recipient) substrate, which engineered forms will accept modified substrates that are not as readily utilized by the wild-type forms of those enzymes. Methods for making and using such engineered enzymes. Modified substrates and methods of making and using them. Methods for using such engineered enzymes and such modified substrates to identify the recipient substrates the enzymes act upon, to measure the extent of such action, and to measure whether test compounds modulate such action.
