Venue and Travel Information

Conference Description

This meeting brings together an international group of researchers who share interests in the mechanisms of protein transport across and into cellular membranes. Protein transport is fundamental to the biogenesis of organelles and cellular membranes. Numerous human and plant pathologies are related to protein mistargeteing or the secretion of virulence factors. In 2018, the meeting present the latest breakthroughs in transport mechanisms in eukaryotes and prokaryotes, with a particular focus on how frontier developments in imaging technologies are providing near atomic resolution on the structure and function of cellular components that mediate protein transport events. Sessions are organized around different topical foci, including targeting of proteins to membranes, protein translocation across and into membranes, quality control mechanisms, regulation of translocation, protein secretion in pathogens, and new paradigms in protein translocation. Talks by invited speakers will be supplemented by shorter talks chosen from abstract submissions. The conference provides opportunities for the interaction of both established leaders in the field and early career scientists who will become the leaders in the future.

Related Meeting

This GRC will be held in conjunction with the "Protein Transport Across Cell Membranes (GRS)" Gordon Research Seminar (GRS). Those interested in attending both meetings must submit an application for the GRS in addition to an application for the GRC. Refer to the associated GRS program page for more information.
