Secondary Information

Protein Function Gelsolin superfamily proteins have roles in a diversity of cellular processes; regulation of actin dynamics; antiapoptotic role; inhibit Aß-induced neurotoxicity; increased expression of gelsolin in oxidative stress helps cells to escape death. Gelsolin is a calcium-regulated actin binding protein that severs and caps actin filaments. Gelsolin's severing activity is important for regulating actin filament assembly dynamics that are required for cell motility as well as survival.
Biochemical Properties on calcium or pH signaling, gelsolin becomes activated and can sever actin filaments;
