WebJul 25, 2016 · When BICD2N and/or dynactin were added to the assay, they were mixed with dynein at 1:5:2 molar ratio (dynein/dynactin/BICD2N) and incubated at 4 °C for 5 min before adding the complex to beads. WebIn this model, RZZ complex inhibition of the KMN network is modulated by the microtubule minus-end-directed motility of dynein/dynactin, which is linked to the outer kinetochore via SPDL-1 and the RZZ complex . When dynein/dynactin is laterally attached to a microtubule that extends past the kinetochore, the RZZ complex is under low tension …
WebCytoplasmic dynein is a eukaryotic motor protein complex that, along with its regulatory protein dynactin, is essential to the transport of organelles … WebThe different dynein complexes hydrolyze MgATP at different rates, for example, the microtubule stimulated ATPase activity of cow brain cytoplasmic dynein is 0.3 μmol min …
WebFor instance, Dm Spindly is dispensable for kinetochore recruitment of dynactin (a dynein-associated complex) and of the SAC protein Mad2 (Griffis et al. 2007), while SPDL-1 appears to be essential for kinetochore recruitment of both these proteins (Gassmann et al. 2008). The origin of these differences is currently unclear.
