An actin-binding protein; a Ca2+-triggered actin-filament-severing protein; hence, it has roles in locomotion, secretion, and endocytosis.

* * *

gel·sol·in (jel-solґin) any of a family of actin-binding proteins that sever and cap actin filaments at high calcium concentrations, thus controlling the length of actin filaments and lowering the viscosity of cytoplasm in processes such the formation of filopodia. They also bind to phosphatidylinositol bisphosphate, linking actin organization and signal transduction. See also profilin.
