Disruption of iron metabolism resulting from Dmt1/Slc11a2 deficiency compromises Notch protein degradation and transcriptional activation

open access: yesThe FEBS Journal, EarlyView.
Divalent metal transporter 1 (Dmt1) maintains iron homeostasis and lysosomal proteostasis required for physiological Notch receptor–ligand signaling. Dmt1 loss lowers iron storage capacity (ferritin), increasing intracellular Fe2+, driving ROS and lipid peroxidation, and leading to lysosomal/mitochondrial dysfunction.

Biogenesis of TNF‐α‐insights into proteostasis and inflammation

open access: yesThe FEBS Journal, EarlyView.
TNF‐α biogenesis, trafficking, and signalling are tightly and reciprocally coupled to cellular proteostasis systems, including ER chaperones and endoplasmic reticulum‐associated degradation. This bidirectional crosstalk determines whether TNF‐α responses are adaptive or proteotoxic.

Long‐read sequencing‐based atlas of tissue‐specific expression of DNM1L transcript variants

open access: yesThe FEBS Journal, EarlyView.
Targeted long‐read sequencing resolves full‐length DNM1L (Drp1) isoforms and reveals conserved, tissue‐specific expression patterns across human and mouse tissues. Functional assays show that Drp1 isoforms differ in their ability to drive mitochondrial fission, independent of abundance, with specific exons modulating activity.

The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

open access: yesThe FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Ubiquitin and ubiquitin‐like modifications in the endoplasmic reticulum stress response

open access: yesThe FEBS Journal, EarlyView.
Endoplasmic reticulum (ER) stress activates various proteostasis control processes, including the unfolded protein response, ribosome‐associated quality control, and ER‐associated degradation. Ubiquitin and ubiquitin‐like modifications dynamically regulate these processes to determine cell fate, promoting adaptation or inducing cell death.

Enhanced exonuclease–Cas9 systems promote multiple nucleotide deletions with higher efficiency and broader targeting scope in plants

open access: yesJournal of Integrative Plant Biology, EarlyView.
Cas9 preferentially generates small indels. By tethering an exonuclease and a DNA‐binding domain (DBD) to Cas9, the Exo‐DBD‐Cas9 system efficiently promotes multiple nucleotide deletions. These expanded deletions enable effective disruption of miRNA‐mediated regulation and relieve translational repression through targeted editing of 3′ untranslated ...

The ZmRACK1–ZmCDPK7–ZmAPX1 module regulates plant antiviral immunity

open access: yesJournal of Integrative Plant Biology, EarlyView.
In maize, ZmRACK1 acts as a scaffold protein that bridges the cyclin‐dependent kinase ZmCDPK7 and the ascorbate peroxidase ZmAPX1, promoting ZmAPX1 activity to mitigate MCMV infection. Upon viral infection, P31 obstructs formation of the ZmRACK1‐ZmCDPK7‐ZmAPX1 complex, inhibiting ZmCDPK7‐mediated ZmAPX1 activity and promoting reactive oxygen species ...
