for the development of functional modulators of pseudokinases that have been
linked to the development of many diseases but which have not been targeted
so far. Efficient development of allosteric inhibitors would require an even better
understanding of the molecular mechanisms of kinase regulation and the dynamic
properties of these enzymes. The fraction of the kinome that has been successfully
targeted is still quite small despite the large number of disease associations that
have been identified for kinases that have not been extensively studied as targets
for the development of drugs [8]. It is therefore likely that many new kinases will
be explored for the development of new medicines in the future.
