Identification of the Mouse T Cell ADP-Ribosylome Uncovers ARTC2.2 Mediated Regulation of CD73 by ADP-Ribosylation

Frontiers in Immunology, 2021
Mouse T cells express the ecto-ADP-ribosyltransferase ARTC2.2, which can transfer the ADP-ribose group of extracellular nicotinamide adenine dinucleotide (NAD+) to arginine residues of various cell surface proteins thereby influencing their function ...

Enterovirus infections in children

Pediatric Investigation, EarlyView.
Enteroviruses (EVs) are major pathogens causing a wide spectrum of diseases in children worldwide. This review summarizes the epidemiology, virology, viral replication, and virus‐host interactions of EVs. It also highlights current advances in clinical diagnosis, antiviral therapies, and vaccine development, providing insights into future strategies ...

Epigenetic Regulation of Liver Fibrosis: Mechanisms and Therapeutic Implications

Portal Hypertension &Cirrhosis, EarlyView.
This review synthesizes the epigenetic mechanisms—DNA methylation, histone modifications, and non‐coding RNAs—that drive hepatic stellate cell activation and the progression of liver fibrosis. It further evaluates emerging therapeutic strategies targeting these epigenetic regulators, including DNA methyltransferase and histone deacetylase inhibitors ...

RNF13 regulates the endolysosomal pathway through interaction with the small GTPase Arl8B

The FEBS Journal, EarlyView.
The E3 ubiquitin ligase RNF13 functions as a regulatory scaffold, organizing Arl8B‐dependent complexes and tuning downstream signaling that controls endolysosomal organization and trafficking. In this model, wild‐type RNF13 associates with Arl8B on endolysosomes, whereas Arl8B (E22D/F55A) or RNF13 (L244A) variants weaken complex assembly, potentially ...

Tankyrase‐2 regulates adipocyte differentiation through AMPK/mTOR signaling

The FEBS Journal, EarlyView.
Tankyrase 2 (TNKS2), a PARP family member, underpins adipocyte differentiation. TNKS2 controls LKB1 protein level, and consequently, the activity of the mTOR/AMPK system and adipocyte differentiation through a layered process. Pharmacological inhibition of TNKS2 leaves other PARPs and DNA repair active and therefore represents a novel target in ...

Biochemical and Developmental Characterization of ADP-ribosylation Factors, A Family of 20 kDa Guanine Nucleotide-binding Proteins

The cholera toxin A subunit (CT-A) is an ADP-ribosyltransferase; its principal cellular substrates are the α subunits of Gs, the stimulatory G protein of adenylyl cyclase.

Structures of the UBR4 complex reveal a giant arena to capture diverse substrates for ubiquitin chain elongation

The FEBS Journal, EarlyView.
This review summarizes recent structures of the UBR4 complex, a giant E4 ubiquitin ligase which recognizes proteins with pre‐existing ubiquitin modifications and marks them for degradation. The UBR4 complex uses a large arena lined with substrate interaction modules to select features on ubiquitinated substrates, such as the presence of N‐degrons or ...

Phosphorylation of BigH1 regulates its expression pattern and promotes embryonic development

The FEBS Journal, EarlyView.
Phosphorylation is a key regulator of the linker histone variant BigH1 during Drosophila embryogenesis. We reveal that N‐terminal phosphorylation promotes the timely removal of BigH1 from chromatin. In contrast, C‐terminal phosphorylation supports early nuclear divisions and embryonic viability.

The nucleosome-remodeling ATPase ISWI is regulated by poly-ADP-ribosylation.

PLoS Biology, 2008
ATP-dependent nucleosome-remodeling enzymes and covalent modifiers of chromatin set the functional state of chromatin. However, how these enzymatic activities are coordinated in the nucleus is largely unknown.
