P.60 right column 2nd paragraph:"Single-molecule studies suggest that dynein walks in a hand-over-hand-like fashion (Figure 2b), although its stepping behavior and directionality are more irregular than kinesin's [refs 6, 7, 8 and 9••]. Evidence has shown that dynein advances via coordination of its two motor domains [refs 8 and 32], but the details of cytoplasmic dynein's step size, stall force, and directionality remain controversial [refs 6, 7, 8, 9•• and 33]. Observations of variable step sizes (4–32 nm) and directionality suggest a considerable diffusional component to its step, making dynein stepping more akin to that of myosin VI (21–51 nm) [primary source] than kinesin." |
