A family case of fertile human 45,X,psu dic(15;Y) males [PDF]

open access: yes, 2006
We report on a familial case including four male probands from three generations with a 45,X,psu dic(15;Y)(p11.2;q12) karyotype. 45,X is usually associated with a female phenotype and only rarely with maleness, due to translocation of small Y chromosomal

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Proton translocation in proteins [PDF]

open access: yes, 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.

Mechanisms of parasite‐mediated disruption of brain vessels

open access: yesFEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

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

open access: yesEvolutionary 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

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

Full-length prepro-alpha-factor can be translocated across the mammalian microsomal membrane only if translation has not terminated. [PDF]

open access: yes, 1988
We have previously shown that fully synthesized prepro-alpha-factor (pp alpha F), the precursor for the yeast pheromone alpha-factor, can be translocated posttranslationally across yeast rough microsomal (RM) membranes from a soluble, ribosome-free pool.

Evaluating the Applicability of the Fokker-Planck Equation in Polymer Translocation: A Brownian Dynamics Study

open access: yes, 2014
Brownian dynamics (BD) simulations are used to study the translocation dynamics of a coarse-grained polymer through a cylindrical nanopore. We consider the case of short polymers, with a polymer length, N, in the range N=21-61.

Controlling Polymer Capture and Translocation by Electrostatic Polymer-Pore Interactions [PDF]

open access: yes, 2017
Polymer translocation experiments typically involve anionic polyelectrolytes such as DNA molecules driven through negatively charged nanopores. Quantitative modelling of polymer capture to the nanopore followed by translocation therefore necessitates the

ERK1/2-dependent phosphorylation and nuclear translocation of PKM2 promotes the Warburg effect

open access: yesNature Cell Biology, 2012
Pyruvate kinase M2 (PKM2) is upregulated in multiple cancer types and contributes to the Warburg effect by unclear mechanisms. Here we demonstrate that EGFR-activated ERK2 binds directly to PKM2 Ile 429/Leu 431 through the ERK2 docking groove and ...
