摘要

Endophilin I is a brain-specific protein functioning in clathrin-mediated endocytosis. The present invention is based on the finding that the rat germinal center kinase-like kinase (rGLK), a member of the germinal center kinase (GCK) family of c-jun N-terminal kinase (JNK) activating enzymes, is a novel endophilin I-binding partner. In a first aspect of the present invention, the novel interaction between endophilin I and rGLK is put to use in a novel screening assay. In a second aspect of the present invention, the interaction between endophilin I and GLK is modulated for therapeutic purposes, namely for the prevention and/or curtailment of neurological disorders associated with the JNK pathway. JNK-mediated neuronal cell death is believed to play an important role in injuries and diseases involving neuronal degeneration, such as Huntington's disease.
