From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Conference Report: Challenging Construction Grammar: New Insights from Morphology (8–12 April 2024; Monte Verità, Switzerland)

open access: yesZeitschrift für Wortbildung
As reflected in its title, this workshop, which took place from the eighth to the twelfth of April 2024 at Monte Verità, Ascona, Switzerland, focused on constructional perspectives in their application to morphology (Hoffmann & Trousdale 2013).

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

A United Effort on an Autonomous Island

open access: yesFafnir, 2016
Year 2015 saw a Nordic alliance on the Convention front. Instead of hosting their own events on their respective mainlands, Swedish and Finnish fandoms joined forces to hold a con together. They chose the most neutral area possible, Åland, an autonomous

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

The ubiquitin system in normal and infected germinal center B cells

open access: yesFEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Conference Report: The Legacies of Ursula K. Le Guin

open access: yesFafnir, 2019
When Ursula K. Le Guin passed away last January, her absence left a hole in the hearts of many in the speculative-fiction community, as much for loss of her personal grace and wit as for her outsized contributions to the field. Understandably, many felt
