ABSTRACT
|
|
|
| |
|
ASK1, a member of the MAPK Kinase Kinase family of proteins has been shown to
play a key role in cancer, neurodegeneration and cardiovascular diseases and is
emerging as a possible drug target. Here we describe a 'replacement-soaking'
method that has enabled the high-throughput X-ray structure determination of
ASK1/ligand complexes. Comparison of the X-ray structures of five ASK1/ligand
complexes from 3 different chemotypes illustrates that the ASK1 ATP binding site
is able to accommodate a range of chemical diversity and different binding
modes. The replacement-soaking system is also able to tolerate some protein
flexibility. This crystal system provides a robust platform for ASK1/ligand
structure determination and future structure based drug design.
