Dynamic Clustering of Dyneins on Axonal Endosomes: Evidence from High-Speed Darkfield Imaging

Abstract One of the fundamental features that govern the cooperativity of multiple dyneins during cargo trafficking in cells is the spatial distribution of these dyneins on the cargo. Geometric considerations and recent experiments indicate that clustered distributions of dyneins are required for effective cooperation on micron-sized cargos. However, very little is known about the spatial distribution of dyneins and their cooperativity on smaller cargos, such as vesicles or endosomes
