Serine residues in proteins are the primary targets for PARP-dependent ADP-ribosylation signalling upon DNA damage.

ARH3 is an enzyme that hydrolyses serine ADP-ribosylation, a recently uncovered post-translational protein modification.

Interactions between serines and molecules of ADP-ribose play an important role in signaling that the DNA in a cell has been damaged and needs to be repaired.

Amino-acid induced Sec body formation is mediated by PARP16 dependent MARylation of Sec16, a component of the endoplasmic reticulum exit site.

In C. elegans and mouse neurons, the balance between poly(ADP-ribose) glycohydrolases and poly(ADP-ribose) polymerases regulates axon regeneration downstream of DLK-1/MAPKKK signaling.

A molecular model of the assembled COPI coat, determined by cryo-electron tomography of an in vitro reconstituted budding reaction, reveals details of interactions mediating coat assembly and shows the binding site of ArfGAP2.

Dysfunction of pyramidal neuron-PV interneuron circuits contributes to cognitive failure in Alzheimer's disease.

An ensemble of cryo-EM structures reveals how eukaryotic elongation factor 2 positions the first codon of a viral mRNA for translation.

A novel BAC transgenic mouse model reveals glial restriction of P2X7 expression in the central and peripheral nervous systems.
