A protein kinase switch
| October 2, 2000
Kinase inhibitors are plagued by a lack of specificity. Now in the 21 September Nature Bishop et al. tackle the problem by building on their earlier work, in which they modified the ATP-binding sites of Src-family tyrosine kinases to accept either nucleotide analogs or modified kinase inhibitors. In the new work the researchers mutate kinases from four distinct kinase families by replacing a bulky residue with a small residue. This change provides enough room for the binding of inhibitor analogs
