STRUCTURE OF HUMAN AURORA-A 122-403 PHOSPHORYLATED ON THR287, THR288
Overview
Aurora-A is an oncogenic kinase essential for mitotic spindle assembly. It, is activated by phosphorylation and by the microtubule-associated protein, TPX2, which also localizes the kinase to spindle microtubules. We have, uncovered the molecular mechanism of Aurora-A activation by determining, crystal structures of its phosphorylated form both with and without a 43, residue long domain of TPX2 that we identified as fully functional for, kinase activation and protection from dephosphorylation. In the absence of, TPX2, the Aurora-A activation segment is in an inactive conformation, with, the crucial phosphothreonine exposed and accessible for deactivation., Binding of TPX2 triggers no global conformational changes in the kinase, but pulls on the activation segment, swinging the ...
