Endocytosis is an essential eukaryotic cell process that is required to regulate cell surface composition. In addition to this role, endocytic pathways are associated with a range of diseases including Alzheimers, Huntington’s and cancer. They can also be exploited to serve as entry routes for pathogens and toxins, furthering the need to understand more about the complex mechanisms involved. Clathrin-mediated endocytosis is a well-characterized pathway in both yeast and mammalian cells. Several alternative endocytic pathways have now been described in mammalian cells that can be clathrin, actin, dynamin, Cdc42 and Arf6- dependent or independent. The factors that determine the type of endocytic pathway used are still poorly understood. Research in the model organism Saccharomyces cerevisiae has been central to our current understanding of the mechanism of membrane invagination at the onset of the endocytic process. Some 50 proteins have been demonstrated to co-localize at endocytic, actinassociated patches in S.cerevisiae. To date, a single clathrinmediated pathway has been described and studied in detail. This pathway is characterized by the sequential assembly of coat proteins and adaptors such as clathrin and the YAP180 homologues, followed by recruitment of actin polymerization machinery which facilitates the invagination of the membrane. Vesicle scission is then achieved by function of the yeast dynamin homologue Vps1 and an amphiphysin heterodimer, Rvs161\/Rvs167. Intriguingly, deletion of several components which block function of actin polymerization machinery, including the type 1 myosins or the Wasp homologue, inhibit invagination but do not appear to preclude uptake of bulk lipid or fluid measured through use of the FM4-64 or Lucifer yellow dyes. This continued uptake of membrane and fluid phase markers when the known pathway is CPI-613 purchase<\/a> inhibited indicates the possibility of other endocytic pathways. Genetic evidence, indicates that there is overlap, or redundancy, among some of the known actin patch components. For example, Abp1 is an actin-binding protein that co-localizes to actin patches at the cell surface but its deletion has no clear defects on the behaviour of commonly used endocytic reporters. Abp1 deletion however, is lethal when combined with deletions in any of three other genes, sla1D, sla2D, and sac6D. The proteins encoded by these other three genes all have defined roles and effects in classical endocytosis. This result has been taken to mean that there are multiple proteins performing the same role within a single endocytic patch complex.<\/p>\n","protected":false},"excerpt":{"rendered":"
