Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Specific Cleavage of the Nuclear Pore Complex Protein Nup62 by a Viral Protease [PDF]

Journal of Biological Chemistry, 2010
Previous work has shown that several nucleoporins, including Nup62 are degraded in cells infected with human rhinovirus (HRV) and poliovirus (PV) and that this contributes to the disruption of certain nuclear transport pathways. In this study, the mechanisms underlying proteolysis of Nup62 have been investigated.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Quantitative regulation of nuclear pore complex proteins by O-GlcNAcylation

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2013
The nuclear pore complex (NPC) is a macromolecular assembly consisting of approximately 30 different proteins called nucleoporins. Several nucleoporins are O-GlcNAcylated, which is a post-translational modification in which the monosaccharide β-N-acetylglucosamine (GlcNAc) is attached to serine or threonine residues within proteins.

ZC3HC1 has functions distinct from TPR and is dispensable for TPR localisation to the nuclear basket [version 1; peer review: 1 approved, 2 approved with reservations]

Wellcome Open Research
Background The nuclear basket is a ‘fishtrap’-like structure on the nucleoplasmic face of the nuclear pore complex which has been implicated in diverse functions including RNA export, heterochromatin organisation, and mitosis. Recently, a novel component

A designer FG-Nup that reconstitutes the selective transport barrier of the nuclear pore complex

Nature Communications, 2021
Intrinsically disordered FG-Nups line the Nuclear Pore Complex (NPC) lumen and form a selective barrier where transport of most proteins is inhibited, whereas specific transporter proteins are able to pass.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Recruitment of Host Nuclear Pore Components to the Vicinity of Theileria Schizonts

mSphere, 2020
Parasitic protozoans of the genus Theileria are intracellular pathogens that induce the cellular transformation of leukocytes, causing uncontrolled proliferation of the infected host cell.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

The leader proteins of Theiler’s virus and Boone cardiovirus use a combination of short linear motifs (SLiMs) to target RSK kinases to the nuclear pore complex

Journal of Virology
Unrelated pathogens, including viruses and bacteria, use a common short linear motif (SLiM) to interact with cellular kinases of the RSK (p90 S6 ribosomal kinase) family.
