The universal eukaryotic DNA replication kinetics is the consequence of simple physicochemical rules resulting from the localisation of potential replication origins at discrete sites and the diffusion of limiting origin firing factors in the nuclear space.
Dynactin acts as an anti-catastrophe factor that extends microtubule growth; posteriorly elucidating a new essential step in oskar mRNA localisation and providing a novel mechanism by which motor-dependent transport can amplify the polarity of MT networks.
Two methyl-binding domain proteins have interdependent functions in embryonic stem cells, and this interdependency extends to the DNA methylation/hydroxymethylation machinery.
During centrosome maturation, pericentrin is delivered to the centrosome co-translationally by a microtubule- and dynein-dependent process, as pericentrin mRNA is undergoing active translation near the centrosome.
Live-cell nanometer-resolution RNA labeling method enables transcriptome-wide mapping of endogenous RNAs in nuclear, cytosol, ER, and mitochondrial subcompartments.
Regulation of conserved Nodal factors by a maternal protein ensures that Nodal signaling is repressed until the appropriate time in embryonic development.
In vitro reconstitution of mRNA motility reveals the basis of directionally biased motion by groups of motors, their response to potential obstacles, and the consequences of reaching microtubule ends.
