Deconstructing gelsolin: identifying sites that mimic or alter binding to actin and phosphoinositides.
Gelsolin is involved in cytoskeletal remodeling as it can fragment and guide reassembly of actin networks. Recent advances in defining the structure of gelsolin identified functionally important sites. These structural insights could lead to the design of small molecule analogs to enhance, inhibit or mimic the functions of gelsolin.
