Abstract : The Endosomal Sorting Complex Required for Transport (ESCRT) is an evolutionarily conserved membrane remodeling machinery that is best known for its essential function in the intra-endosomal sorting of ubiquitinated growth factor receptors towards the intra-lumenal vesicles of multivesicular endosomes. In addition to this role in endosomal biogenesis, a number of studies have led to the identification of additional roles of the ESCRT machinery in processes ranging from cytokinetic abscission to membrane repair and exovesicle release. While the ESCRT complex has been studied extensively with respect to its function in the endocytic regulation of cell signaling, much less is known with respect to the physiological relevance of these more recently discovered ESCRT activities. Our lab uses Drosophila and Zebrafish to study ESCRT function in animal development. In the course of this work, we have found that ESCRT proteins are detected on extracellular vesicles that are present in the lumenal space of epithelial organs in both fish and flies. The data that I will present suggest that ESCRT-positive exovesicles may play an important role in the extracellular transport of developmental signaling molecules.
