Crystal Structure of Fyn kinase domain complexed with staurosporine
Overview
The tyrosine kinase Fyn is a member of the Src kinase family. Besides the, role of Fyn in T cell signal transduction in concert with Lck, its excess, activity in the brain is involved with conditions such as Alzheimer's and, Parkinson's diseases. Therefore, inhibition of Fyn kinase may help, counteract these nervous system disorders. Here, we solved the crystal, structure of the human Fyn kinase domain complexed with staurosporine, a, potent kinase inhibitor, at 2.8 A resolution. Staurosporine binds to the, ATP-binding site of Fyn in a similar manner as in the Lck- and, Csk-complexes. The small structural differences in the, staurosporine-binding and/or -unbinding region among the three kinase, domains may help obtaining the selective inhibitors against the respective, kinases.
