Mammalian N1-adenosine PARylation is a reversible DNA modification

open access: yesNature Communications, 2022
Poly-ADP-ribosylation (PARylation) is a well-known posttranslational modification of proteins. Here the authors show that beyond proteins also mammalian single-stranded DNA is PARylated in vitro and in vivo.

Tissue-Specific Posttranslational Modification Allows Functional Targeting of Thyrotropin

open access: yesCell Reports, 2014
Thyroid-stimulating hormone (TSH; thyrotropin) is a glycoprotein secreted from the pituitary gland. Pars distalis-derived TSH (PD-TSH) stimulates the thyroid gland to produce thyroid hormones (THs), whereas pars tuberalis-derived TSH (PT-TSH) acts on the

Structure of the planar cell polarity cadherins Fat4 and Dachsous1

open access: yesNature Communications, 2023
Fat and Dachsous are large cadherins that regulate planar polarity as a receptor:ligand pair. Here, authors determine the structure of the Fat:Dachsous complex to uncover the molecular determinants of binding and posttranslational modification.

Protein glutaminylation is a yeast-specific posttranslational modification of elongation factor 1A [PDF]

open access: yes, 2017
Ribosomal translation factors are fundamental for protein synthesis and highly conserved in all kingdoms of life. The essential eukaryotic elongation factor 1A (eEF1A) delivers aminoacyl tRNAs to the A-site of the translating 80S ribosome.

The Nervous System Cytoskeleton under Oxidative Stress

open access: yesDiseases, 2013
Oxidative stress is a key mechanism causing protein aggregation, cell death and neurodegeneration in the nervous system. The neuronal cytoskeleton, that is, microtubules, actin filaments and neurofilaments, plays a key role in defending the nervous ...

An Anti‐Amyloidogenic Approach to Specifically Block Memory Consolidation in Mice for Therapeutic Intervention

open access: yesAdvanced Science, EarlyView.
Functional amyloid conversion of the translation regulator CPEB3 is essential for long‐term memory persistence. This study demonstrates that targeting this molecular switch with the anti‐amyloidogenic peptide QBP1 selectively blocks CPEB3 fibrillation without disrupting phase separation.

Posttranslational modification of human glyoxalase 1 indicates redox-dependent regulation. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Glyoxalase 1 (Glo1) and glyoxalase 2 (Glo2) are ubiquitously expressed cytosolic enzymes that catalyze the conversion of toxic alpha-oxo-aldehydes into the corresponding alpha-hydroxy acids using L-glutathione (GSH) as a cofactor.

Regulation of the water channel aquaporin-2 by posttranslational modification

open access: yes, 2011
The cellular functions of many eukaryotic membrane proteins, including the vasopressin-regulated water channel aquaporin-2 (AQP2), are regulated by posttranslational modifications.

Site-Specific Modification and Segmental Isotope Labelling of HMGN1 Reveals Long-Range Conformational Perturbations Caused by Posttranslational Modifications [PDF]

open access: yes, 2020
Interactions between histones, which package DNA in eukaryotes, and nuclear proteins such as the high mobility group nucleosome-binding protein HMGN1 are important for regulating access to DNA.
