This meeting will provide a unique, open, inclusive and interactive forum for the international and domestic research community working on ESCRT biology and be an effective learning environment for all participants, especially graduate students, postdocs and other researchers from diverse backgrounds.

The endosomal sorting complex required for transport (ESCRT) machinery comprises a series of different factors (about 30 proteins in humans; about 45 in plants) that facilitate membrane remodeling and fission reactions throughout the cell.

Over the past decade, there has been an explosion in the number of processes now known to be ESCRT-mediated, including endosomal protein trafficking, cytokinetic abscission, closure of the post-mitotic nuclear envelope, enveloped virus budding, exosome biogenesis, neuronal pruning and membrane repair. Furthermore, ESCRT-like systems have recently been discovered in archaea and bacteria, making this one of the most highly conserved machines in nature. 

This meeting will bring together experts in disciplines as diverse as biophysics, plant biology, cell biology, biochemistry and structural biology from around the world to cover key aspects of ESCRT biology.

Graduate students, postdocs and other researchers established in or wishing to learn about ESCRT biology are encouraged to attend and submit abstracts. The organizers will select oral presenters and there will be a poster session.

Middle: Verdant plant life growing from an interwoven VIPP1 ring structure. VIPP1 (vesicle-inducing protein in plastids) is a conserved membrane-remodeling protein that builds the thylakoid membranes of cyanobacteria, algae and plants. VIPP1, along with its bacterial homolog PspA, are recently described members of the ESCRT-III superfamily of membrane remodelers, extending the conservation of ESCRT-III across all major domains of life.
