== Publication Abstract from PubMed ==
 +
beta-Thymosin (betaT) and WH2 domains are widespread, intrinsically disordered actin-binding peptides that display significant sequence variability and different regulations of actin self-assembly in motile and morphogenetic processes. Here, we reveal the structural mechanisms by which, in their 1:1 stoichiometric complexes with actin, they either inhibit assembly by sequestering actin monomers like Thymosin-beta4, or enhance motility by directing polarized filament assembly like Ciboulot betaT. We combined mutational, functional or structural analysis by X-ray crystallography, SAXS (small angle X-ray scattering) and NMR on Thymosin-beta4, Ciboulot, TetraThymosinbeta and the long WH2 domain of WASP-interacting protein. The latter sequesters G-actin with the same molecular mechanisms as Thymosin-beta4. Functionally different betaT/WH2 domains differ by distinct dynamics of their C-terminal half interactions with G-actin pointed face. These C-terminal interaction dynamics are controlled by the strength of electrostatic interactions with G-actin. At physiological ionic strength, a single salt bridge with actin located next to their central LKKT/V motif induces G-actin sequestration in both isolated long betaT and WH2 domains. The results open perspectives for elucidating the functions of betaT/WH2 domains in other modular proteins.

[[http://www.uniprot.org/uniprot/ACTS_RAT ACTS_RAT]] Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells. [[http://www.uniprot.org/uniprot/TYB4_BOVIN TYB4_BOVIN]] Plays an important role in the organization of the cytoskeleton. Binds to and sequesters actin monomers (G actin) and therefore inhibits actin polymerization (By similarity). Seraspenide inhibits the entry of hematopoietic pluripotent stem cells into the S-phase.
