  "summary": "Gelsolin is a master regulator of the actin cytoskeleton whose activity is controlled by large Ca2+ dependent conformational transitions of its 6 domains (G1-G6). Despite decades of biochemical and cellular studies, the structural basis of activation of the full-length protein remains poorly understood because active gelsolin is highly dynamic and has largely escaped structural characterization.…",
