Compromised DNA replication in gut cells underlies sensitivity to genotoxic stress in the tardigrade Hypsibius exemplaris

open access: yesThe FEBS Journal, EarlyView.
DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

The sorting nexin Snx21 promotes flotillin‐mediated endocytosis

open access: yesThe FEBS Journal, EarlyView.
In this study, we describe a novel function of the previously uncharacterized Snx21 protein as a specific positive regulator of flotillin‐mediated endocytic trafficking. Snx21 is recruited to endosomal membranes via binding to PI(3)P, and it colocalizes with flotillins on the surface of late endosomes.

Structural insights into θ‐type carbonic anhydrases 3 and 4: Tuning the directionality of CO2 hydration in a diatom

open access: yesThe FEBS Journal, EarlyView.
θ‐CA3 from a marine diatom has an N‐terminal transmembrane helix and two homologous catalytic domains. The enzyme functions as a dimer, with active sites formed near the dimer interface. A bicarbonate ion binds on the symmetry axis of the dimer and forms hydrogen bonds with both monomers, thereby activating θ‐CA3 and tuning CO2 hydration activity ...

GSK3α‐mediated regulation of the RNA demethylase fat mass and obesity‐associated protein (FTO) during murine spermatogenesis

open access: yesThe FEBS Journal, EarlyView.
FTO regulates mRNA stability and translational efficiency through its m6A‐demethylation activity. GSK3 functions as an upstream regulator of FTO, leading to its inhibition via phosphorylation. In male germ cells, FTO activity is kept in check by GSK3α.

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 ...

RLIM‐associated neurodevelopmental disorders: From clinical spectrum to molecular mechanisms

open access: yesThe FEBS Journal, EarlyView.
RLIM (RNF12) is an E3 ubiquitin ligase essential for mammalian development. Loss‐of‐function variants cause Tønne–Kalscheuer syndrome, while duplications cause Xq13 duplication syndrome, highlighting RLIM dosage sensitivity. This review summarizes the genetics, clinical features, and molecular mechanisms of RLIM‐associated disorders, integrating ...
