AnneResearch summary

Microtubules are essential for chromosome segregation, intracellular transport, positioning of organelles, directed cell migration and differentiation. All these processes require the organisation of microtubules into arrays with different geometry and density and the proper regulation of dynamics and interactions at the microtubule ends. My lab focuses on the mechanisms that generate specific microtubule arrays in polarised cells and on the dynamic interactions of microtubule tips with intracellular structures and the cell cortex to control cell shape changes and directed cell migration. To do this we combine quantitative live cell imaging approaches with in vitro reconstitution assays.

M13wobblewobbly phages as nanosensors

This paper demonstrates the use of a fluorescently-labelled and surface-anchored bacteriophage M13 to measure wall shear stress. Bacteriophage anchored on collagen-coated slides and the surface of endothelial cells were subjected to various levels of shear stress by modulating buffer flow through the imaging chamber.

HSP70chaperoning the spindle

We describe Nek6-dependent spindle recruitment of Hsp70, which is required for K-fibre stability and function. Data generated in the Straube lab suggest that the weak direct interaction of Hsp70 with microtubules is not affected by the Nek6-mediated phosphorylation at T66. Thus Hsp70 possibly acts by recruiting the chTOG/TACC3/Clathrin complex to spindle microtubules.

MAP4zippering microtubules

Here, we identify a previously uncharacterised isoform of microtubule-associated protein MAP4, oMAP4, as a microtubule organising factor that is crucial for myogenesis. Depletion of oMAP4 impairs cell elongation and cell-cell fusion. oMAP4 is required for paraxial microtubule organisation in muscle cells and prevents dynein- and kinesin-driven microtubule-microtubule sliding. Purified oMAP4 aligns dynamic microtubules into antiparallel bundles that withstand motor forces in vitro.

EMLmicrotubule binding motif revealed

In this paper we identify the MT-binding domain in EML proteins. Daniel and Anne performed TIRF-based MT binding assays using full-length, mutant and truncation constructs of human EML1 fused to YFP. We show that EML contains a trimerisation domain that is required, but not sufficient for MT binding.

podosomeskinesin under MAP control

Here we show that the kinesin KIF1C is required for the de-novo formation of podosomes in vascular smooth muscle cells. We describe a pathway whereby activation of PKC results in the enrichment of CLASPs at microtubule ends, which stimulates KIF1C translocation to the cell periphery, where KIF1C localises to incipient podosome sites.

In this paper we describe a computational framework to analyse and classify cell morphology. The approach uses a machine learning process based on the calculation of a shape similarity matrix and low-dimensional representation of cell shapes using diffusion map. We show that this approach is suitable for the highly variable cell shapes observed in migrating epithelial cells.

spaghettimicrotubule rigidity

In this paper we investigate the flexural rigidity of microtubules that have been stabilised by Taxol, non-hydrolysable GTP analogs or two different microtubule-associated proteins, tau and MAP4. We find that Taxol and GTPγS make microtubules more flexible, while tau and GMP-CPP make them stiffer. We show that combinations of these stabilisers do not have additive effects, but rather one stabiliser dominates the mechanical properties. MAP4 is not changing rigidity per se, but limits the variability of rigidity between microtubules.

AnneAnne Straube | PI

After a Diploma in Biochemistry and Molecular Biology from the University of Hamburg, Germany, I joined the lab of Gero Steinberg at the Ludwig Maximilian University in Munich and later at the Max Planck Institute for Terrestrial Microbiology in Marburg. Fo my PhD project I studied the microtubule cytoskeleton in the fungus Ustilago maydis, concentrating in particular on the dynamic re-organisation of microtubules during the cell cycle and on intracellular transport by the molecular motors dynein and kinesin, which carry traffic along microtubules. I then moved as a Postdoctoral Fellow of the Emmy Noether programme of the German Science Foundation (DFG) to the Wellcome Trust Centre for Cell Biology in Edinburgh, where I worked with Andreas Merdes on the microtubule cytoskeleton in differentiating muscle cells. In 2007, after three years in Edinburgh, I started my own lab at the Marie Curie Research Institute (MCRI) in Oxted, Surrey. When the MCRI closed in 2010, I moved with my colleagues Rob Cross and Andrew McAinsh to the University of Warwick to found the Centre for Mechanochemical Cell Biology.

Kinesin motors perform the long-distance transport towards the plus end of microtubules. Thus kinesins are likely to be responsible for delivering polarity factors to the cell edges. I have identified Kif1C as the transporter for rearward transport of integrins in migrating cells and shown that this transport supports tail stability and rear drag, a mechanism important for directionally persistent cell migration in the absence of external guidance cues (Theisen et al., Dev Cell 2012).

AndrewAndrew McAinsh | CMCB | Warwick

Andrew and I collaborate since I started my lab at the Marie Curie Research Institute. We share an interest in live cell imaging and what microtubules do when they arrive at subcellular structures, the kinetochore or the cell cortex. We have successfully combined our expertise investigating MAP4 and CLASP1 and dynein in mitotic spindle positioning (Samora et al., Nature Cell Biology, 2011).

JennyJenny Ross | UMass | Amherst

Jenny and I first met at the "Microtubule Dynamics" workshop I organised at the Marie Curie Research Institute. We met later at the EMBL Microtubule conference and decided to do some work together. Jenny has helped us with dynein gliding assays to prove the direct role of MAP4 in controlling dynein force generation (Samora et al., Nature Cell Biology, 2011) and we have provided her lab with MAP proteins to study the mechanical properties of microtubules in the presence of various microtubule stabilisers (Hawkins et al., Biophysical Journal, 2013).

Andrew, Richard and I collaborate on the structure and function of EML proteins, microtubule-associated proteins that form oncogenic fusion proteins with tyrosine kinases (Richards et al., Biochem J 2015).

IrinaIrina Kaverina | Vanderbilt University

Irina and I share an interest in how dynamic microtubules control directional cell migration. We have recently documented our ideas on this in a review article (Kaverina & Straube, Seminars Cell Dev Biol, 2011). We held a joint lab retreat in May 2012 and currently collaborate on the role of microtubules and the motor Kif1C in podosome formation (Efimova et al., J Cell Science 2014) and on the microtubule plus tip complex (Grimaldi et al., Developmental Cell 2014).

PapaEkkehard Straube | Physik | Universität Halle

My father is a (retired) theoretical physicist who applies his knowledge of polymer physics to the analysis of our cell migration tracks. He has contributed a directional persistence analysis program to our recent paper on the role of Kif1C-mediated stabilisation of trailing adhesions in directed cell migration (Theisen et al., Developmental Cell, 2012).

SteveSteve Royle | CMCB | Warwick

Since becoming office neighbours, Steve and I have started to collaborate on aspects of clathrin's microtubule binding properties (Hood et al., Journal of Cell Biology, 2013). In the future we want to exploit our complementary expertise to understand the handing over of vesicles from clathrin-mediated endocytosis to microtubule-based transport.
