Anna Akhmanova studied biochemistry and molecular biology at the Moscow State University. She received her PhD in 1997 at the University of Nijmegen. She worked as a post-doc at the Department of Microbiology and Evolutionary Biology at the University of Nijmegen and at the Department of Cell Biology at the Erasmus Medical Center in Rotterdam. In 2001, she has started her own research group at the Department of Cell Biology at the Erasmus Medical Center. Since 2011, Anna Akhmanova is professor of Cell Biology at Utrecht University.
Anna Akhmanova is a recipient of the ALW Vernieuwingsimpuls VIDI (2001) and VICI awards (2007), and an ERC Synergy grant (2013). She is the Chair of the board of the Netherlands Microscopy Society and a member of the European Molecular Biology Organization (EMBO).

My group studies cytoskeletal organization and trafficking processes, which contribute to cell polarization, differentiation, vertebrate development and human disease. We are interested in understanding, at a systems level, in how different aspects of cell architecture are coordinated.
The main focus of our studies is the microtubule cytoskeleton. Our research relies on combining high-resolution live cell imaging and quantitative analysis of cytoskeletal dynamics, measurement of protein dynamics using advanced microscopic assays, in vitro reconstitution of dynamic cytoskeleton-based processes and different methods of identification of protein-protein interactions (in vitro binding studies, pull-down assays, yeast two-hybrid screens and mass spectrometry-based protein identification). In addition to cultured cells, we employ mouse knockout technologies and couple mouse genetic modification (such as GFP knock-in technology) to live tissue imaging. In collaboration with mathematicians we are working on development of automated analysis and modeling of cytoskeletal dynamics and vesicle transport.
One of the main topics of our research is the structure and function of microtubule plus-end tracking proteins - a group of factors that associate specifically with the growing microtubule ends, regulate microtubule dynamics and their interactions with various cellular structures, such as the actin cytoskeleton, focal adhesions and cell-cell contacts.
In another line of study, we investigate molecular mechanisms of microtubule-based vesicle transport. We identified several linkers between vesicles and microtubule motors and developed novel assays to demonstrate specific functions of these linkers in recruitment of motor proteins to membrane organelles. As a model system, we are currently investigating the process of constitutive exocytosis, which received relatively little attention in the literature in spite of its fundamental importance.
Microtubule-based processes are essential for cell division, normal functioning of large cells such as neurons and for intracellular transport of pathogens; therefore, our studies are relevant for combating abnormal cell proliferation, neurodegeneration and infectious diseases.
Microtubules play an essential role in mitosis, positioning and movement of cellular organelles, maintenance of cell shape and cell motility. Microtubules are highly dynamic: they continuously switch between phases of growth and shrinkage. This phenomenon, termed dynamic instability, is essential for formation and remodeling of microtubule networks.
Microtubules are hollow cylindrical polymers, which are intrinsically polarized. Microtubule plus-ends are the fast-growing ends in vitro and the only ends that grow in cells. The opposite (minus) ends can slowly grow in vitro, while in cells they are usually stabilized or serve as the sites of disassembly. A number of specialized proteins and protein complexes that are conserved in all eukaryotes specifically accumulate at growing microtubule plus ends, and are collectively referred to as plus-end-tracking proteins (+TIP). We are interested in understanding how +TIPs interact with microtubule ends and with each other, and how they regulate microtubule dynamics and microtubule interactions with different cellular structures.
+TIPs include motors, adaptors and linker proteins from different structurally unrelated families. They all share the capacity to form comet-like accumulations at the growing microtubule tips.

Many +TIPs do not recognize the plus ends directly but rather bind to them through the highly conserved members of the EB (End Binding) protein family.
Some +TIPs specifically localize to certain cellular structures, such as mitotic kinetochores or the cell cortex, and regulate microtubule dynamics in the vicinity of these structures. For example, CLASPs stabilize microtubules at the leading edge of migrating fibroblasts.
Localization of CLASP2 (green) to the leading edge of a migrating mouse 3T3 fibroblast. Stable (acetylated) microtubules are shown in red.
Our studies are aimed at revealing the functions of +TIPs and the molecular mechanisms underlying their activities. They heavily rely on advanced microscopy techniques such as wide field, confocal and Total Internal Reflection Fluorescence Microscopy with high spatial and temporal resolution.

Various cellular organelles (mitochondria, peroxisomes, lysosomes, endosomes, ER- and Golgi-derived vesicles) are transported within cells along cytoskeletal tracks. Long-range intracellular transport occurs along microtubules and depends on kinesin and dynein motors. Cytoplasmic dynein (as opposed to flagellar dyneins, which are responsible for the movements of the cilia and flagella) is a microtubule minus end-directed motor, which is involved in the transport of membrane organelles, mRNAs and protein complexes. The aim of our research is to understand how dynein is linked to various cargos and how dynein activity is coordinated with that of plus end-directed motors, kinesins, present on the same cargos. We also investigate how different signaling pathways regulate motor activities.
Our current studies are focused on the evolutionary conserved adaptor protein Bicaudal D, which can interact with dynein-dynactin complex and also with kinesin-1. In flies, Bicaudal D plays an important role in dynein-dependent polarized transport of mRNAs. In mammalian cells, Bicaudal D homologues are involved in dynein-dependent transport of exocytotic vesicles positive for the small GTPase Rab6, as well as in dynein and kinesin-mediated positioning of the nucleus and the centrosome at the onset of mitosis.
Bicaudal D1 (green) and Rab6 (red) colocalise at the Golgi complex and cytoplasmic vesicles in interphase HeLa cells.
Dual color time lapse live imaging of a Rab6-postive exocytotic vesicle (green) moving on a microtubule (red). Note that the vesicle changes the direction of movement: it switches from plus end directed to minus end directed transport.
We use multicolor microscopy techniques such as wide field, confocal and Total Internal Reflection Fluorescence Microscopy with high spatial and temporal resolution to study vesicle movement along microtubules and different biochemical techniques to investigate the interactions of Bicaudal D2 with motors and cargo molecules.

- Characterization of the signaling pathways regulating Bicaudal D association with motors and cargos
Exocytotic carriers exit from the Golgi apparatus, move along microtubule tracks towards cell periphery and then fuse with the plasma membrane. Recently, we found that the same cortical complexes are involved in attachment of microtubule plus ends to the plasma membrane and in promoting vesicle fusion. These complexes contain the lipid binding protein LL5β and the adaptor protein ELKS (also known as ERC1 or Rab6IP2). These complexes depend on integrins for their localization at the plasma membrane and are intimately associated with focal adhesions.
Our aim is to understand how these complexes are assembled and regulated, how they control microtubule attachment and dynamics, and what is the molecular mechanism underlying the ability to enhance vesicle fusion. Since ELKS protein was also found as an important part of the NF-κB signaling pathway, we are also interested in the functional interactions between the components of this pathway, microtubule stabilization and vesicle fusion machinery.
Cortical patches positive for LL5β (red) serve as microtubule attachment sites in a HeLa cell (microtubules are shown in green).
Cortical patches positive for LL5β (green) accumulate around focal adhesions visualized by staining for focal adhesion kinase (red). This phenomenon is particularly apparent when microtubules are disassembled with microtubule-depolymerizing drug nocodazole.
