Probing JNK MAPK function with peptide inhibitors. It has generally been accepted that the JNK MAPK family of protein kinases is rapidly and potently activated following the exposure of mammalian cells to stresses and cytokines. However, their biological role has remained controversial. We believe that this problem reflects the lack of a generally applicable and specific JNK MAPK inhibitor.

It has generally been accepted that the JNK MAPK family of protein kinases is rapidly and potently activated following the exposure of mammalian cells to stresses and cytokines. However, their biological role has remained controversial. We believe that this problem reflects the lack of a generally applicable and specific JNK MAPK inhibitor. In this project we continue our characterisation of a small peptide inhibitor developed in our laboratories. We aim to determine its mechanism of inhibition, the specificity of interaction, and to evolve more effective inhibitors. With these new inhibitors, we can effectively address the biological roles of these kinases.Read moreRead less
