Na+-dependent and Na+-independent betaine transport across the apical membrane of rat renal epithelium [PDF]
The low renal excretion of betaine indicates that the kidney efficiently reabsorbs the betaine filtered by the glomeruli but the mechanisms involved in such a process have been scarcely investigated.

CAVER 3.0: A Tool for the Analysis of Transport Pathways in Dynamic Protein Structures
Tunnels and channels facilitate the transport of small molecules, ions and water solvent in a large variety of proteins. Characteristics of individual transport pathways, including their geometry, physico-chemical properties and dynamics are instrumental

Bovine Serum Albumin Rejection by an Open Ultrafiltration Membrane: Characterization and Modeling
The classic application of ultrafiltration (UF) is for the complete retention of proteins, and in that situation, the transport behavior is well established.

Non-Markovian Quantum Jumps in Excitonic Energy Transfer [PDF]
We utilize the novel non-Markovian quantum jump (NMQJ) approach to stochastically simulate exciton dynamics derived from a time-convolutionless master equation.

Molecular Mimicry of SecA and Signal Recognition Particle Binding to the Bacterial Ribosome
Bacteria execute a variety of protein transport systems for maintaining the proper composition of their different cellular compartments. The SecYEG translocon serves as primary transport channel and is engaged in transporting two different substrate ...

MAP7 regulates axon morphogenesis by recruiting kinesin-1 to microtubules and modulating organelle transport. [PDF]
Neuronal cell morphogenesis depends on proper regulation of microtubule-based transport, but the underlying mechanisms are not well understood.

Plant cells are unique as they carry two organelles of endosymbiotic origin, namely mitochondria and chloroplasts (plastids) which have specific but partially overlapping functions, e. g., in energy and redox metabolism.

The mutations that cause Leber congenital amaurosis (LCA) lead to photoreceptor cell death at an early age, causing childhood blindness. To unravel the molecular basis of LCA, we analyzed how mutations in LCA5 affect the connectivity of the encoded ...

Direct quantitation of peptide-mediated protein transport across a droplet-interface bilayer.
We introduce a new method for monitoring and quantitating the transport of materials across a model cell membrane. As a proof-of-concept, the cell-penetrating peptide, Pep-1, was used to carry horseradish peroxidase (HRP) across droplet-interface ...

Diversification and expression of the PIN, AUX/LAX, and ABCB families of putative auxin transporters in \u3cem\u3ePopulus\u3c/em\u3e [PDF]
Intercellular transport of the plant hormone auxin is mediated by three families of membrane-bound protein carriers, with the PIN and ABCB families coding primarily for efflux proteins and the AUX/LAX family coding for influx proteins. In the last decade
