The trimeric Shu complex in C. elegans is an ATPase that remodels RAD51 filaments in the homologous recombination‐associated DNA damage response

open access: yesThe FEBS Journal, EarlyView.
The C. elegans Shu complex (RFS‐1/RIP‐1/SWS‐1) is a DNA‐dependent ATPase that regulates RAD‐51 filaments during homologous recombination. The trimer preferentially binds 5′‐exposed DNA, remodels RAD‐51 filaments via ATP hydrolysis, and stabilizes filaments through ATP binding.

Structures of the UBR4 complex reveal a giant arena to capture diverse substrates for ubiquitin chain elongation

open access: yesThe FEBS Journal, EarlyView.
This review summarizes recent structures of the UBR4 complex, a giant E4 ubiquitin ligase which recognizes proteins with pre‐existing ubiquitin modifications and marks them for degradation. The UBR4 complex uses a large arena lined with substrate interaction modules to select features on ubiquitinated substrates, such as the presence of N‐degrons or ...

Phosphorylation of BigH1 regulates its expression pattern and promotes embryonic development

open access: yesThe FEBS Journal, EarlyView.
Phosphorylation is a key regulator of the linker histone variant BigH1 during Drosophila embryogenesis. We reveal that N‐terminal phosphorylation promotes the timely removal of BigH1 from chromatin. In contrast, C‐terminal phosphorylation supports early nuclear divisions and embryonic viability.

Crystal structure of human NIF3‐like protein reveals dynamic hexameric assembly with a single divalent metal binding site

open access: yesThe FEBS Journal, EarlyView.
We present the first crystal structures of human NIF3, revealing a dynamic, hexameric ring with a central cavity regulated by flexible insertion domains. Crucially, human NIF3 features a mononuclear zinc‐binding site, marking a distinct evolutionary departure from the dinuclear centers of bacterial homologs.

Dragonfly taxonomic and functional responses to urbanized streams in southeastern Europe, with management recommendations

open access: yesInsect Conservation and Diversity, EarlyView.
Urbanization drives turnover in dragonfly species composition, traits, and habitat conservation value. Natural stream sections have a higher conservation value (higher DBI) due to presence of specialists. Properly managed urban streams can support diverse dragonfly assemblages.
