Calcium 23-30 gelsolin Homo sapiens 34-42 9398317-1 1997 Gelsolin is a calcium-regulated actin severing and capping protein that binds two calcium ions and has three sites for actin; two recognize monomeric actin and one attaches to the sides of filaments. Calcium 14-21 gelsolin Homo sapiens 0-8 9398317-1 1997 Gelsolin is a calcium-regulated actin severing and capping protein that binds two calcium ions and has three sites for actin; two recognize monomeric actin and one attaches to the sides of filaments. Calcium 82-89 gelsolin Homo sapiens 0-8 9398317-3 1997 Here, we have analyzed the effects of calcium ions on (i) limited proteolysis of bacterially expressed human gelsolin by plasmin and (ii) dynamic light scattering and circular dichroism of gelsolin and various of its subdomains. Calcium 38-45 gelsolin Homo sapiens 109-117 9398317-4 1997 Following cleavage of gelsolin in the absence of calcium between Lys150 and His151 (the junction between G1 and G2), the molecule does not fall apart, nor does it bind actin without added calcium. Calcium 188-195 gelsolin Homo sapiens 22-30 9398317-6 1997 The noncovalently linked form of gelsolin shows three actin binding sites in calcium and requires 3 microM calcium for 50% activation of actin binding. Calcium 77-84 gelsolin Homo sapiens 33-41 9398317-6 1997 The noncovalently linked form of gelsolin shows three actin binding sites in calcium and requires 3 microM calcium for 50% activation of actin binding. Calcium 107-114 gelsolin Homo sapiens 33-41 9398317-7 1997 Measurements of light scattering and circular dichroism revealed structural changes in response to calcium for intact gelsolin and a number of its actin-binding subdomains. Calcium 99-106 gelsolin Homo sapiens 118-126 9398317-9 1997 These results are discussed in relation to the calcium control of gelsolin function and its three-dimensional structure (Burtnick et al.
