Summary of Meeting:
The eukaryotic cytoskeleton is composed of three distinct protein polymer systems: microtubules, actin filaments, and intermediate filaments. These cytoskeletal systems differ from each other in a variety of fundamental ways, and each is associated with characteristic accessory and regulatory proteins. For these reasons, the three systems have classically been studied in isolation. However, it is becoming increasingly apparent that interactions between microtubules, actin filaments, and intermediate filaments not only occur in vivo, but are essential for a variety of fundamental cellular processes ranging from cell division and cell locomotion, to polarity development during early embryogenesis and neuronal path finding. The recent inroads into understanding the cellular and molecular bases of cytoskeletal systems interactions have resulted from advances in high resolution imaging techniques as well as the application of molecular, genetic and biochemical approaches to identify proteins that directly and indirectly link the three systems. This meeting will draw together investigators who are studying the interactions of cytoskeletal systems in different cellular processes, using different approaches, and employing different model organisms. The goal of the meeting is to elucidate the cellular behaviors in which cytoskeletal interactions play a key role, to determine the fundamental types interactions between cytoskeletal systems, discuss their degree of conservation or specialization in different processes, and identify key molecules mediating these interactions. Accordingly, the presentations are structured such that each day combines a series of talks from investigators using a systems approach, to provide cellular context, with a series of talks from investigators working at a more reductionistic level, to provide insights into the functioning of key molecular players.
