Versatile and sensitive detection of mono- and poly(ADP-ribosyl)ation reveals XRCC1-dependent remodelling of PARP1 signalling

open access: yesNature Communications
ADP-ribosylation has long been recognised as a key regulator of essential signalling pathways, including the DNA damage response. However, only recent and ongoing technological advances are beginning to make it possible to investigate its distinct forms ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Preserving ester-linked modifications reveals glutamate and aspartate mono-ADP-ribosylation by PARP1 and its reversal by PARG

open access: yesNature Communications
Ester-linked post-translational modifications, including serine and threonine ubiquitination, have gained recognition as important cellular signals. However, their detection remains a significant challenge due to the chemical lability of the ester bond ...

The Critical Role of PARPs in Regulating Innate Immune Responses

open access: yesFrontiers in Immunology, 2021
Poly (adenosine diphosphate-ribose) polymerases (PARPs) are a family of proteins responsible for transferring ADP-ribose groups to target proteins to initiate the ADP-ribosylation, a highly conserved and fundamental post-translational modification in all

A target repurposing approach identifies N-myristoyltransferase as a new candidate drug target in filarial nematodes [PDF]

open access: yes, 2014
Myristoylation is a lipid modification involving the addition of a 14-carbon unsaturated fatty acid, myristic acid, to the N-terminal glycine of a subset of proteins, a modification that promotes their binding to cell membranes for varied biological ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

SnapShot: ADP-Ribosylation Signaling [PDF]

open access: yesMolecular Cell, 2015
Intracellular protein ADP-ribosylation is catalyzed by diphteria toxin-like ADP-ribosyltransferases (ARTDs, formerly PARPs) ("writers"), which use NAD(+) for the modification of different amino acids. While some ARTD members catalyze protein poly-ADP-ribosylation, most of them are mono-ADP-ribosyltransferases.

In vivo vizualisation of mono-ADP-ribosylation by dPARP16 upon amino-acid starvation

open access: yeseLife, 2016
PARP catalysed ADP-ribosylation is a post-translational modification involved in several physiological and pathological processes, including cellular stress.
