Abstract

Biological membranes are two dimensional, making the discovery of quasi-one-dimensional diffusion of membrane proteins puzzling. Jaqaman et al. (2011) now show that actomyosin and tubulin interact to establish long, thin diffusion corridors, thereby increasing the effective concentration of select membrane proteins to promote their interactions and modulate signaling.
