Phasic microfilament behaviors of the growth and stabilization of cortical actin caps are driven by distinct combinations of actin regulatory proteins, which display features of a deep competition for G-actin.

Phosphorylation of Aurora A does not trigger a population shift to the active state as previously thought, but instead switches the kinase on by tuning the structure and dynamics of a dynamically sampled subpopulation.
A critical review of the limitations posed by current preclinical animal models of Alzheimer's disease and of the oversimplistic assumptions proposed by the amyloid cascade hypothesis (ACH).
The striking reduction in open probability of CFTR channels harboring the R117H cystic fibrosis mutation is caused by loss of a strong hydrogen bond between positions 117 and 1124, which is formed in wild-type channels selectively in the open state.
Smurf1 and Smurf2 have essential functions in the mammalian Shh signaling pathway, binding to and ubiquitylating Patched1, leading to its endocytosis and subsequent degradation in lysosomes.

Disulfide-bridged fibroblast growth factor 2 (FGF2) dimerization at the inner plasma membrane leaflet produces the building block for higher FGF2 oligomers that drive FGF2 membrane translocation into the extracellular space.
The pathogen Acinetobacter baumannii recognises preacinetobactin not acinetobactin, yet appears likely to translocate both compounds through a mixed complex.

Integrated biophysical, structural, and in-cell approaches demonstrate a non-canonical and non-isomerizable binding motif-dependent mode of protein kinase C regulation by the peptidyl-prolyl isomerase Pin1 in mammalian cells.
