  28.  J. Xu, Z. Shu, S.J. King, and S.P. Gross, "Tuning Multiple Motor Travel Via Single Motor Velocity", Traffic, March 27, (2012). [pdf]
    Shows that for multiple-motor based transport, velocity can be used to control mean travel. For single kinesin motors, processivity is independent of velocity, which means that the slower you go, the lower the single-motor off rate. Thus, for multiple motors acting together, since the "on" rate is independent of velocity, but the off-rate is not,?the ratio of on-rate to off-rate can be tuned by velocity, and this can be used to quite dramatically alter how far the group of motors takes the cargo.

    Discovers a new pathway of kinesin inactivation/reactivation. Shows that kinesin by itself tends to go inactive, and that this inactivation can be reversed by the presence of CK2, both in vitro and in vivo. Importantly, this new inactivation/reactivation pathway does NOT involve autoinhibition of kinesin via the established head-tail inactivation pathway, as even tail-less kinesin goes inactive.

  34. A. Kunwar, Kunwar, S.K. Tripathy, J. Xu, M.K. Mattson, P. Anand, R. Sigua, M. Vershinin, R.J. McKenney, C. C. Yu, A. Mogilner+†, and S.P. Gross+†, "Mechanical stochastic tug-of-war models cannot explain bidirectional lipid-droplet transport", PNAS, November 14, (2011). [pdf]
    Investigates theoretically how multiple kinesin and dynein motors function together. By comparing theory and experiments, it concludes that straightforward mechanistic tug-of-war scenarios are inconsistent with observed motion for bi-directional lipid droplet motion, suggesting additional coordination mechanism likely exist.
  35. J. Yi, K. Ori-McKenney, R. McKenney, M. Vershinin, S.P. Gross, and R. B. Vallee, "High Resolution Imaging Reveals Indirect Coordination of Opposite Motors and LIS1 Role in High-load Axonal Transport.", J. Cell Biol., (2011).?[pdf]
    A paper following-up on the in-vitro study (#53, below) of Dynein"s regulation by NudE and Lis1, but this time looking at transport in cells. The main points are 2. First, that coordination between opposite motors (for bi-directionally moving transport) is NOT directly and immediately mediated by activity of the motors. That is, when dynein (minus-end) activity is decreased rapidly (by acute inhibition), plus-end motion is inhibited, but with a temporal delay. Thus, however motor inactivation is sensed (potentially by force production, or other mechanisms), once detected, inactivation of the opposite motors requires some additional feedback mechanism. This is consistent with the fact that in vitro, neither kinesin or dynein require opposite-polarity motors to be present to function. The second point of the paper is that in neurons, larger cargos appear likely to be exposed to significantly more opposition to motion, so that their appropriate transport requires NudE/Lis1 function, but this?requirement is much less for smaller cargos.

    Discovers that loss of CAV1 function can result in multiple disease phenotypes by affecting Mitochondrial function. CAV1 is discovered to contribute to mitochondrial cholesterol homeostasis, and by altering cholesterol in the mitochondrial membrane,?loss of CAV1 function thus results in a variety of alterations of mitochondrial function.

    Determines the mechanistic effects of the LOA mutation, a mutation in the dynein heavy chain, that leads to an ALS-like phenotype in heterozygous mice bearing the mutation. Homozygous mice die at birth. The paper has a number of main findings. First, that the mutation decreases single-molecule processivity. Second, that this defect carries over to multiple-motor transport, and the effects on processivity at the single-molecule can quantitatively explain?the observed impairment in multiple-motor based transport, likely resulting in the observed disease phenotype. This study thus provided the first direct experimental evidence supporting the long=hypothesized importance of single-motor processivity for healthy transport. The study also suggests a role for the tail in controlling enzymatic coordination between the two heads. Because this loss of enzymatic coordination correlates with increased side-to-side stepping of the motor, and hence less lateral contact between the two heads, we believe this is consistent with a mechanism whereby dynein heads communicate with each other laterally.

    Discovers the mechanistic role of NudE and Lis1. Briefly, NudE alone both recruits dynein to a particular location, but also inactivates it. Lis1 then binds NudE, and the combined Dynein-NudE-Lis1 complex is again active, but now with improved performance. In particular, the complexes processivity is increased, and more importantly, detachment under load is decreased. This allows the motors to "hold on" under load, and is critical in allowing multiple motors to work well together. In the presence of NudE and Lis1, the same number of motors can exert a higher average force, not because each motor exerts more force, but rather because on average more motors are engaged (they don"t fall off).

    A brief review discussing a paper from the Lipowsky group that recently appeared in PNAS.

    A previous PNAS paper (#38, below) investigated how two or three kinesin motors function together, and showed that tau"at levels found in cells"can function to regulate the number of engaged motors, allowing cells the possibility to spatially regulate plus-end transport via control of track (microtubule) accessibility. This raised the potential problem of cross-talk between plus-end and minus-end transport, since they both occur along microtubules. In this manuscript we investigate dynein"s sensitivity to tau, in both the single- and multiple-motor regimes. We show that filament-level regulation can occur without cross-talk, because dynein is essentially unaffected by the low levels to moderate levels to tau that so significantly alter kinesin-based transport. Using a construct (a portions of dynein"s microtubule-binding domain), we investigate how dynein avoids kinesins" tau sensitivity.

    Investigates properties of different step-detection methods, and then applies the best one to the problem of how multiple kinesin motors function together. It shows that under low load, and saturating ATP, in vitro two kinesin motors attached to a cargo do not coordinate, but instead function independently, so that the center of mass of the cargo moves in ~4nm steps.

    A review of advances in our understanding of how multiple motors move cargos, and the ramifications of the number of engaged motors moving cargos.

    Uses mass spectrometry to determine the proteins present on embryonic lipid droplets.?Because the proteins present are found to be highly conserved between Drosophila and mammalian droplets, this suggests that studying the Drosophila droplets can provide important insights into the similar processes in mammals. In the proteome, certain unexpected proteins"histones"are present in large amounts The localization of histones to the droplets is investigated in depth, and concluded to be real, and temporally regulated. Based on these findings, together with published observations from others, the manuscript proposes a new model for lipid droplets as generalized sites of protein storage/sequestration.

    Investigates how two or three dynein motors function together, and shows that stall forces for motors are additive, and that multiple dynein motors move cargos very long distances. Shows that a cargo moved by two dyneins is expected to move a very long distance, so that for cargos moved by two or more dynein motors in cells, the dynactin complex (which increases dynein processivity) is likely unnecessary as far as facilitating travel distance. This does not?mean, however, that the dynactin complex is unimportant"we have previously shown that in some cases it plays a role in coordinating kinesin and dynein, and others have shown that it frequently plays an important role in dynein-cargo attachment.
