Until recently, dynein was the least understood of the cytoskeletal motors.
However, a wealth of new structural, mechanistic, and cell biological data is
shedding light on how this complicated minus-end-directed, microtubule-based
motor works. Cytoplasmic dynein-1 performs a wide array of functions in most
eukaryotes, both in interphase, in which it transports organelles, proteins,
mRNAs, and viruses, and in mitosis and meiosis. Mutations in dynein or its
regulators are linked to neurodevelopmental and neurodegenerative diseases. Here,
we begin by providing a synthesis of recent data to describe the current model of
dynein's mechanochemical cycle. Next, we discuss regulators of dynein, with
particular focus on those that directly interact with the motor to modulate its
recruitment to microtubules, initiate cargo transport, or activate
minus-end-directed motility.
