GtoPdb Ligand ID: 9271

PDB Ligand
Compound class: Synthetic organic
Comment: Mps1, a dual-specificity kinase, is required for the proper functioning of the spindle assembly checkpoint and for the maintenance of chromosomal stability. MPS1-IN-1 leads to defects in Mad1 and Mad2 establishment at unattached kinetochores, decreased Aurora B kinase activity, premature mitotic exit and gross aneuploidy. In addtion inhibitor treatment resulted in a decrease in cancer cell viability [1]. While this is included in the Probe Portal as SGC MPS1-IN-1, it is superceded by more potent and specific compounds.
