Fast amoeboid migrating cells require both cofilin-1 and ADF for fast actin turnover at 'leader bleb' necks.

HS-AFM and Principal Component Analysis provide experimental evidence to substantiate the 'proof of principle' regarding the flexible helical twists of actin filaments that regulate the functions of actin-binding proteins.

A cluster of cofilin along an otherwise bare actin filament induces distinctively asymmetric cooperative conformational changes to the filament on either side of the cluster.

Both cooperative and competitive associations of actin binding proteins with actin filaments help drive the self-organization of functionally diverse F-actin networks in fission yeast.

Three-dimensional fluorescence imaging of microbial eukaryotes in environmental samples allows accurate automated taxonomic profiling and quantitative data about ultrastructures and interactions of organisms.

Telomeric proteins Taz1 or Mit1 specifically regulate telomere association of condensin which is essential for sister-telomere disjunction in mitosis by restraining telomere association of cohesin.

Bacterial warfare protein colicin E1 opens its hinge to plug antibiotic efflux pump TolC and potentiate antibiotics.

Selfish genetic elements may either promote or prevent the evolution of reproductive barriers, depending on the extent of gene flow between species.

Profilin release from the filament end controls the speed of actin growth at physiological conditions.

Single-cell FRET measurements reveal large temporal activity fluctuations within this signaling pathway in Escherichia coli, caused by stochasticity of receptor methylation combined with allosteric interactions and slow rearrangements within receptor clusters.
