Energetic gradients emerge in developing motor-microtubule structures

Ana I. Duarte, Gabriel L. Salmon, Heun Jin Lee…·Rob Phillips

The paper measures ATP gradients in motor-microtubule assemblies and shows they are sustained by energy consumption, with implications for cytoskeletal organization.

Motor-driven microtubule diffusion in a photobleached dynamical coordinate system

Soichi Hirokawa, Heun Jin Lee, Rachel A. Banks…·Rob Phillips

The paper investigates motor-driven microtubule network contraction and identifies a diffusive-like spread within the network, showing a conserved relationship between contraction rates and diffusion constants.
