| Outline of Final Research Achievements |
MIG-17, an ADAMTS metalloprotease controls migration of gonadal distal tip cells (DTCs) through regulation of extracellular matrix in C. elegans. In the present study, we asked why the mutation in a ribosomal protein RPL-20(G82R) can suppress the DTC migration defect in the mig-17 mutants. Although we could not reach a clear understanding of the mechanism, we found that RPL-20(G82R) does not affect the regulatory mechanism of translational initiation. We also showed that RPL-20(G82R) is not secreted, but that it appears to act through unknown secreted proteins to suppress the mig-17 defects. We found that the RPL-20 activity is especially important in the intestine for the suppression to occur.
