...Zhilin Yang; Ryan L. Hanson; Eric Batchelor The dynamics of p53 expression provide a mechanism to increase differentiation between cellular stresses and specificity in appropriate responses. Here, we review recent advances in our understanding of the molecular mechanisms regulating p53 dynamics...

.... Membrane funnels (commonly known as necks and pores) are frequently observed as transient states during fusion and fission of membrane vesicles in cells. However, caveolae display atypical dynamics where the membrane funnel can be stabilized over an extended period of time, resulting in cell surface...

... transport of ions. Tight coordination of the motions of the pump is required to couple the two spatially distant processes of ion binding and ATP hydrolysis. Here, we review our current understanding of the structural dynamics of P-type ATPases, focusing primarily on Ca 2+ pumps. We integrate different...

... regions of the protein, which change conformation depending on the nucleotide present, mediate this switch. A large number of X-ray, NMR and simulation studies have shown that this is an over-simplification. The switch regions themselves are highly dynamic and can exist in distinct sub-states in the GTP...

... ribonucleoprotein particles) and numerous protein factors. Assembly of these snRNPs and associated proteins is a highly dynamic process, making it challenging to study the conformational rearrangements and spliceosome assembly kinetics in bulk studies. In the present review, we discuss recent studies utilizing...

... a distribution of Cc orientations around CcP that was similar to the Brownian dynamics ensembles ( Figure 2 A). Then, the average PREs predicted for this ensemble were calculated, representing the predicted PREs for state B. Also, for state C, the PREs were predicted, using the crystal structure as the model...

...Mikael Akke Protein conformational dynamics can be critical for ligand binding in two ways that relate to kinetics and thermodynamics respectively. First, conformational transitions between different substates can control access to the binding site (kinetics). Secondly, differences between free...

... that the same can be true for molecular biology. In particular, and using basic modular methods of mathematical modelling which are standard in control theory, a set of dynamic models is developed for some illustrative cell signalling processes. These models, supported by recent experimental evidence, are used...
