From local asters to global contraction: How filament length and concentration shape microtubule–motor organization

Abstract: How do simple changes in biological building blocks affect the large-scale structures they form? We pursue this question in a system of microtubules and kinesin motors. Microtubules are stiff protein filaments that help organize the interior of cells, while kinesin motors move along them and generate forces. When combined in vitro, microtubules and motors organize in very different ways—from localized asters to contractile structures spanning the entire system. Using simulations guided by experiments, we examine how two basic properties—the concentration of microtubules and their length—control which of these structures emerges. We find that lower concentrations favor localized asters, while higher concentrations promote asters or system-spanning contraction, with filament length strongly shifting the balance between the two. By connecting simulations with experiments, this work shows how simple microscopic properties can determine whether motor-driven filaments organize locally or collectively across much larger scales.
Bio: Dr. Aravind Rao Karanam is a postdoctoral researcher at the Das Lab at at RIT. He studies the dynamics of biopolymer networks using simulations and theory. He received his Ph.D. from UC San Diego where he studied reaction networks in eukaryotic chemotaxis.
