The helical bacterium Helicobacter pylori patterns cell wall synthesis using two distinct cytoskeletal proteins, CcmA and MreB, to achieve its characteristic shape.

The pro-apoptotic BH3-protein Bim contains two distinct binding sites for anti-apoptotic proteins that together confer resistance of Bim/Bcl-2 and Bim/Bcl-XL complexes to BH3-mimetic drugs under development for use in humans.

A simple, yet elegant method for robust self-assembly of diverse membrane proteins into soluble peptide nanoparticles for their structural and functional analysis in detergent-free solutions.
Cell-specific architectural properties such as the axon diameter of the white matter of the human brain can be quantified accurately and non-invasively using diffusion magnetic resonance imaging.
Paul E Schavemaker, Wojciech M Śmigiel, Bert Poolman
The diffusion coefficients of proteins in the cytoplasm depend on their net charge and the distribution of charge over the protein surface, with positive proteins moving up to 100-fold slower because they bind to ribosomes.

A genetically encoded fluorescent biosensor reveals temporally resolved changes to aspartate concentration during genetic, pharmacological, and nutritional manipulations.

The helical cell shape of Helicobacter pylori depends on the polymerizing cytoskeletal protein CcmA’s recruitment to the cell envelope by Csd5 and CcmA’s indirect stabilization of a periplasmic cell wall hydrolase via interactions with the transmembrane protein Csd7.
A new native prion protein aggregation assay shows that syntaxin-6, a risk factor for sporadic Creutzfeldt–Jakob disease, delays prion protein fibril formation and prolongs the presence of toxic aggregation intermediates.

The convergent evolution of unusually strict substrate specificity in apicomplexan LDHs arose by classic neofunctionalization of a duplicated MDH gene via few mutations of large effect.
Airborne PM2.5 exposure triggers oxidative stress and mitochondrial apoptosis in placental trophoblast cells via the KLF9/CYP1A1 transcriptional axis, ultimately leading to adverse pregnancy outcomes.
