Abstract

Dynamin-related proteins are multidomain, mechanochemical GTPases that self-assemble and orchestrate a wide array of cellular processes. Over the past decade, structural insights from X-ray crystallography and cryo-electron microscopy have reshaped our mechanistic understanding of these proteins. Here, we provide a historical perspective on these advances that highlights the structural attributes of different dynamin family members and explores how these characteristics affect GTP hydrolysis, conformational coupling and oligomerization. We also discuss a number of lingering challenges remaining in the field that suggest future directions of study.

Keywords: BSE; GTPase; bundle signaling element; dynamin; dynamin-related proteins; helix.
