LIM domain and actin-binding protein 1 (LIMA1)

Actin-binding protein involved in actin cytoskeleton regulation and dynamics. Increases the amount and size of actin stress fibers and inhibits membrane ruffling.

Inhibits actin filament depolymerization. Bundles actin filaments, delays filament nucleation and reduces formation of branched filaments (PubMed:12566430).
