The present invention relates to polypeptides which comprise the ligand binding domain of Lck, crystalline forms of these polypeptides, and the use of these crystalline forms to determine the three dimensional structure of the catalytic domain of Lck. The invention also relates to the use of the three dimensional structure of the Lck catalytic domain both alone, or in complex with inhibitors, in methods of designing and/or identifying potential inhibitors of Lck activity, for example, compounds which inhibit the binding of a native substrate to the Lck catalytic domain. The invention also relates to the use of the three dimensional structure of the Lck catalytic domain both alone, or in complex with inhibitors, in methods of designing and/or identifying potential selective inhibitors of Lck activity, for example, compounds which inhibit the binding of a native substrate to the Lck catalytic domain selectively.
本发明涉及包含Lck配体结合域的多肽、这些多肽的结晶形式,以及使用这些结晶形式来确定Lck催化域的三维结构。本发明还涉及使用Lck催化域的三维结构,单独或与抑制剂复合物一起,设计和/或识别Lck活性的潜在抑制剂的方法,例如抑制天然底物与Lck催化域的结合的化合物。本发明还涉及使用Lck催化域的三维结构,单独或与抑制剂复合物一起,设计和/或识别Lck活性的潜在选择性抑制剂的方法,例如选择性抑制天然底物与Lck催化域的结合的化合物。
