LIS1 (Pac1) binding slows dissociation of dynein from microtubules

LIS1 is an essential cofactor for the assembly of the cytoplasmic dynein transport machinery. How LIS1 binding affects dynein motility was unclear. Single-molecule experiments reveal that Pac1 (the yeast homolog of LIS1) binding reduces dynein speed by slowing its detachment from microtubules and does not disrupt the mechanism by which it generates force.
