Capping protein modulates the dynamic behavior of actin filaments in response to phosphatidic acid in Arabidopsis.

Remodeling of actin filament arrays in response to biotic and abiotic stimuli is thought to require precise control over the generation and availability of filament ends. Heterodimeric capping protein (CP) is an abundant filament capper, and its activity is inhibited by membrane signaling phospholipids in vitro. How exactly CP modulates the properties of… CONTINUE READING
