Fluorescence lifetime imaging microscopy, paired with fluorescent, voltage-sensitive dyes, provides a method for measuring and quantifying membrane potentials of living cells.

Hemoglobin affinity and cooperativity reveal mechanistic insights in how the relation between physiology and evolutionary variations shape a protein's molecular property.

A protein fragment forms different folded structures when amplified to different copy numbers within a single polypeptide chain.

Eukaryotic replisomes are strongly connected together to replicate both sister DNAs produced from a bidirectional origin.

The cAMP-dependent protein kinase A controls the switch from actively sprouting new blood vessel formation to vessel quiescence by reducing endothelial autophagy through phosphorylation-mediated destabilisation of ATG16L1.

Identification of how bioactive lipids bind and inhibit glycine transporters has the potential to be exploited in the development of a new class of analgesics for chronic pain.

The signaling ligand (p)ppGpp regulates the enzyme HPRT across species by binding to a novel class of conserved motif, yet its specificity is allosterically altered through evolution of enzyme oligomerization.

The rate of DNA unwinding by RecQ helicases is dramatically modulated by the DNA duplex stability in a geometry-dependent manner, providing an intrinsic mechanism for suppressing illegitimate recombination.

Heme accumulation is toxic, but deficiency of the heme transporter HRG1/SLC48A1 causes heme sequestration and crystallization into hemozoin within enlarged lysosomes of macrophages, thereby conferring heme tolerance to mammals.

DNA replication initiation proteins contain a disordered domain that impacts each stage of their function, from chromatin recruitment and initiator co-assembly to the subsequent displacement of the factors from chromatin.
