“…However, interpretation of Nod-gal localization is complicated by in vitro studies showing that Nod lacks directional motor activity and preferentially binds MT plus-ends, rather than minus-ends (Matthies et al, 2001;Cui et al, 2005). Furthermore, both fulllength Nod and the endogenous minus end-directed motor protein cytoplasmic Dynein accumulate at the posterior pole at stage 9, along with the plus-end directed motor protein Kinesin I (Li et al, 1994;Brendza et al, 2002;Duncan and Warrior, 2002;Januschke et al, 2002;Cui et al, 2005). Although the significance of this is not completely clear, it has been speculated that this reflects Kinesin-mediated recycling of Dynein (Duncan and Warrior, 2002;Januschke et al, 2002).…”
