  • Title: New twists in actin-microtubule interactions.
    Author: Pimm ML, Henty-Ridilla JL.
    Journal: Mol Biol Cell; 2021 Feb 01; 32(3):211-217. PubMed ID: 33507109.
    Abstract:
    Actin filaments and microtubules are cytoskeletal polymers that participate in many vital cell functions including division, morphogenesis, phagocytosis, and motility. Despite the persistent dogma that actin filament and microtubule networks are distinct in localization, structure, and function, a growing body of evidence shows that these elements are choreographed through intricate mechanisms sensitive to either polymer. Many proteins and cellular signals that mediate actin-microtubule interactions have already been identified. However, the impact of these regulators is typically assessed with actin filament or microtubule polymers alone, independent of the other system. Further, unconventional modes and regulators coordinating actin-microtubule interactions are still being discovered. Here we examine several methods of actin-microtubule crosstalk with an emphasis on the molecular links between both polymer systems and their higher-order interactions.
