A rapid cascade of regulatory events defines the developmental fates of embryonic cells. However, once established, these developmental fates and the underlying transcriptional programs can be remarkably stable. Here, we describe two proteins, MEP-1 and LET-418/Mi-2, required for maintenance of somatic differentiation in C. elegans. In animals lacking MEP-1(More)
Pan1p is an essential protein of the yeast Saccharomyces cerevisiae that is required for the internalization step of endocytosis and organization of the actin cytoskeleton. Pan1p, which binds several other endocytic proteins, is composed of multiple protein-protein interaction domains including two Eps15 Homology (EH) domains, a coiled-coil domain, an(More)
Endocytosis is a protein and lipid-trafficking pathway that occurs in all eukaryotic cells. It involves the internalization of plasma membrane proteins and lipids into the cell and the subsequent degradation of proteins in the lysosome or the recycling of proteins and lipids back to the plasma membrane. Over the past decade, studies in yeast and mammalian(More)
The role of aggregation of abnormal proteins in cellular toxicity is of general importance for understanding many neurological disorders. Here, using a yeast model, we demonstrate that mutations in many proteins involved in endocytosis and actin function dramatically enhance the toxic effect of polypeptides with an expanded polyglutamine (polyQ) domain.(More)
Centrioles play an important role in organizing microtubules and are precisely duplicated once per cell cycle. New (daughter) centrioles typically arise in association with existing (mother) centrioles (canonical assembly), suggesting that mother centrioles direct the formation of daughter centrioles. However, under certain circumstances, centrioles can(More)
