| Summary: | This invention describes a crystal comprising a purified polypeptide which includes an extracellular domain of the receptor protein tyrosine kinase (RPTK) either alone or in complex with ligands. Further disclosed are properties of the tetragonal space group symmetry and unit cell dimensions. Methods of determination and use are also included for such three dimensional structures of the receptor protein tyrosine kinases and/or their ligands, such as in the design and identification of RPTK modulators, which are useful in the treatment of diseases that are mediated by inappropriate RPTK activity. |
| Abstract: | The determination and use of three dimensional structures of receptor protein tyrosine kinases and/or their ligands are described. One particular group of such structures includes three dimensional structures of the extracellular domain of RPTKs. The three dimensional structures of RPTKs can faciliate the design and identification of modulators of RPTK function. Other such structures can include of RPTK ligands, such as stem cell factor or a fragment thereof. Modulators of RPTK function can be used to treat diseases that are mediated by inappropriate RPTK activity. |
