Investigating Structure and Dynamics of Atg8 Family Proteins

Abstract Atg8 family members were the first autophagy-related proteins to be investigated in structural detail and continue to be among the best-understood molecules of the pathway. In this review, we will first provide a concise outline of the major methods that are being applied for structural characterization of these proteins and the complexes they are involved in. This includes a discussion of the strengths and limitations associated with each method, along with guidelines for successful adoption to a specific problem. Subsequently, we will present examples illustrating the application of these techniques, with a particular focus on the complementarity of information they provide.
