Abstract: E-mail: [email protected]: http://umr168.curie.fr/en/Sykes-groupCell deformations are part of many vital processes such as division, motility orintracellular transport. They result from the continuous re-organization of the actin cytoskeleton underneath the membrane. In order to unveil how biochemical… read more here.

DOI: 10.1038/s41598-020-62942-8
Abstract: The dynamics of actin networks is modulated by a machinery consisting of actin binding proteins that control the turnover of filaments in space and time. To study this complex orchestration, in vitro reconstitution approaches strive… read more here.

DOI: 10.1091/mbc.e18-01-0061
Abstract: How mechanical stress applied to the actin network modifies actin turnover has attracted considerable attention. Actomyosin exerts the major force on the actin network, which has been implicated in actin stability regulation. However, direct monitoring… read more here.

DOI: 10.1093/jxb/erx269
Abstract: In plant cells, molecular connections link the cell wall-plasma membrane-actin cytoskeleton to form a continuum. It is hypothesized that the cell wall provides stable anchor points around which the actin cytoskeleton remodels. Here we use… read more here.

DOI: 10.1242/jcs.258802
Abstract: EphB2/ephrinB signalling that plays a major role in cell segregation during embryonic development and tissue homeostasis, induces an important reorganization of the cortical actin network. We have previously reported that myosin 1b contributes to the… read more here.
