Research Abstract

We analyzed the rme mutants which show defects in yolk uptake by oocytes in C.elegans and identified novel rme genes conserved from the worm to human. We found that the rme-3 gene encodes clathrin. We also revealed that RME-4 functions on coated pits and/or vesicles to recruit small GTPase RAB-35, which in turn functions in the endosomes to promote receptor recycling. We further identified a candidate for the Rab35 effector molecule and examined its functions in endocytosis.
