Improper Primate Release Fuels Interspecific Mating: Cases of Two Mixed‐Species Groups in Bangladesh

Ecology and Evolution
Wildlife trafficking has escalated in recent years, leading to a rise in animal rescues every year. In Bangladesh, increasing numbers of primates are being rescued from illegal trades and private collections.

Exact steady-state velocity of ratchets driven by random sequential adsorption

, 2008
We solve the problem of discrete translocation of a polymer through a pore, driven by the irreversible, random sequential adsorption of particles on one side of the pore.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Translocation arrest by reversible folding of a precursor protein imported into mitochondria [PDF]

, 1989
Passage of precursor proteins through translocation contact sites of mitochondria was investigated by studying the import of a fusion protein consisting of the NH2-terminal 167 amino acids of yeast cytochrome b2 precursor and the complete mouse ...

Directed motion emerging from two coupled random processes: Translocation of a chain through a membrane nanopore driven by binding proteins

, 2005
We investigate the translocation of a stiff polymer consisting of M monomers through a nanopore in a membrane, in the presence of binding particles (chaperones) that bind onto the polymer, and partially prevent backsliding of the polymer through the pore.

Coupled dynamics of RNA folding and nanopore translocation [PDF]

, 2005
The translocation of structured RNA or DNA molecules through narrow pores necessitates the opening of all base pairs. Here, we study the interplay between the dynamics of translocation and base-pairing theoretically, using kinetic Monte Carlo simulations

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Conservation in the Anthropocene: Using Genetics to Understand the Past and Manage for the Future of the Threatened Stephens' Kangaroo Rat

Evolutionary Applications
Habitat loss and fragmentation are major drivers of biodiversity decline, reducing connectivity among populations and leading to genetic isolation, loss of diversity, increased inbreeding, and reduced fitness.

Chromosome territory formation attenuates the translocation potential of cells

eLife, 2019
The formation and spatial arrangement of chromosome territories (CTs) in interphase has been posited to influence the outcome and frequency of genomic translocations.

Proton translocation in proteins [PDF]

, 1989
The active transport of protons across the low dielectric barrier imposed by biological membranes is accomplished by a plethora of proteins that span the ca. 40 Å of the phospholipid bilayer.
