Biogenesis of TNF‐α‐insights into proteostasis and inflammation
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.

Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

Understanding and addressing resistance to IMiDs immunomodulatory compounds in multiple myeloma
IMiDs are pivotal in the treatment of multiple myeloma. Mechanisms of resistance comprise cell intrinsic and extrinsic pathways, involving tumour microenvironment, immune cell dysfunction, CRBN‐dependent and independent genetic drivers and epigenetic changes.

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

Combating ageing beyond the cell: Emerging roles of extracellular proteostasis
Ageing challenges the body's ability to maintain a stable and functional proteome, leading to protein damage and aggregation both inside and outside cells. This review focuses on the less well understood mechanisms of extracellular protein quality control and how they become disrupted in ageing, particularly in neurodegenerative diseases.

Conserved dimerization architecture in C‐type lectins from virus‐vector mosquitoes
C‐type lectins (CTLs) are involved in the detection of viral/microbial carbohydrates. We studied a family of soluble CTLs in the mosquito Aedes aegypti, which acts as a vector for viruses like dengue and Zika. Using crystallography, biophysics, and structure prediction approaches, we found that these proteins consistently pair together in the same ...

In Neurospora crassa, a cytosolic GH18 endo‐β‐n‐acetylglucosaminidase (ENGase) functions as an active deglycosylating enzyme. Deletion of this severely alters tolerance to multiple stress conditions and causes extensive transcriptomic reprogramming, including upregulation of a GH20 exo‐β‐n‐acetylhexosaminidase under ER stress, indicating that N. crassa
