Nature News and Views on Asgard cytoskeleton

Laura Eme and Thijs Ettema have co-authored a News and Views highlighting the Nature publication by Akil and Robinson. In this article, the authors performed in vitro experiment on several Asgard profilins and showed that they were able to regulate the polymerization of eukaryotic actin filaments. This suggests that Asgard archaea also have a (perhaps

Our new ISME Journal paper on archaeal endosymbionts is out now

Ettema Lab in collaboration with  T. Martin Embley (Newcastle University, UK) just published a new paper in the ISME Journal. In our latest publication, we assembled genomes from two archaeal methanogenic endosymbionts living in closely related anaerobic ciliates. Although the endosymbiont species are not close relatives of one another, their genomes show some similar features that could have

Linnaeus Prize for Dr. Daniel Tamarit

Huge congratulations to Ettema Lab member Daniel Tamarit, who will receive the Linnaeus Prize (Linnépriset) by the Royal Society of Sciences at Uppsala for his PhD thesis. The Linnaeus Prize is the oldest prize of the Society through a donation by Carl von Linné’s widow Sara E. Linné. The prize is awarded in time for Linné’s birthday (May 23rd), and publicly celebrated

New Nature publication about the origin of mitochondria

‘Deep mitochondrial origin outside the sampled alphaproteobacteria’ is the brand-new publication in Nature by the Ettema-Lab in collaboration with international partners. This study sought to find the closest living relatives of the mitochondrial ancestor and increased the genomic sample of alphaproteobacteria with 13 previously uncharacterized lineages from the Atlantic and Pacific Ocean. After careful phylogenetic

New paper available: RNA sequencing of Stentor cell fragments reveals key processes underlying cellular regeneration

Ettema Lab is pleased to announce the new paper in Current Biology by Henning Onsbring Gustafson on cellular regeneration in the ciliate Stentor at single cell resolution. Our new study uses transcriptomics of cell fragments of the ciliate Stentor to reveal the importance of protein phosphorylation, microtubule-based processes and genes involved in the cell cycle for cellular regeneration. Check the paper out here!

Pre-print available: Comparison of metagenome-assembled and single-amplified genomes

This collaborative study of the Pinhassi-Lab (Linnaeus University, Kalmar), the KTH Royal Inst. of Technology (SciLifeLab, Stockholm) and the Ettema-Lab can now be read as early pre-print at bioRxiv. The paper reports on the comparison of two culture-independent strategies for recovering bacterial genomes: single-amplified genomes and metagenome-assembled genomes, and its implication for in-depth analyses of uncultivated prokaryotic taxa. Read the paper here. /MS

Nature Microbiology Review is celebrating 40 years of Archaea!

For the 40th anniversary celebration of Archaea at Nature Microbiology Review Ettema Lab is honoured to contribute not only with a review paper but also the cover of this special Dec issue! Our review presents a comprehensive overview regarding the current view of how eukaryotes have evolved from an archaeal ancestor. Join us in the celebration of Archaea

40 YEARS OF ARCHAEA Snapshot: Dr. Thijs Ettema

Nature Microbiology celebrates the 40th anniversary of the seminal publication by Carl R. Woese and George E. Fox with a “40 years of Archaea” channel to reflect on key advances in the field since its inception and discuss what the future may bring. Part of this channel is an interview by senior editor Claudio Nunes-Alves with Thijs Ettema about his experiences in working

Just published: Functional reconstruction of a eukaryotic-like ubiquitylation cascade from an uncultured archaeon

The latest publication of the Robinson-lab (Lancaster University, UK) in collaboration with the Ettema-lab is now available online at Nature Communications, regarding the ‘Functional reconstruction of a eukaryotic-like E1/E2/(RING) E3 ubiquitylation cascade from an uncultured archaeon’ – the first time that the ubiquitination cascade has been demonstrated outside of eukaryotes.  You can read the article here. /MS

Daniel Tamarit joins Ettema-lab

Starting October Ettema-lab welcomes Daniel Tamarit as its newest Postdoc. Daniel defended his PhD one year ago at Siv Andersson’s lab (UU), studying genome evolution in host-associated bacteria. Since then, he has performed evolutionary analyses on a bacterial gene transfer system evolved from domesticated bacteriophages, and on the architecture of bacterial chromosomes. Starting this week, as an integral
