Dynamic property of intermediate filaments: Regulation by phosphorylation

Abstract

Abstract Site‐specific phosphorylation of intermediate filament (IF) proteins on serine and threonine residues leads to alteration of the filament structure, in vitro and in vivo . Protein kinases involved in cell signaling and those activated in mitosis dynamically control spatial and temporal organization of intracellular IF phosphorylation. Thus, IF phosphorylation appears to be one of the most predominant strategies in coordinating intracellular organization of the IF network.
