Structural insights into ADP-ribosylation of ubiquitin by Deltex family E3 ubiquitin ligases

open access: yesScience Advances, 2020
The C-terminal RING and DTC domains of mammalian Deltex proteins catalyze ADP-ribosylation at the C terminus of ubiquitin. Cellular cross-talk between ubiquitination and other posttranslational modifications contributes to the regulation of numerous ...

Immunometabolic and Spatiotemporal Control of Tissue‐Resident Memory T Cell Biology

open access: yesBarrier Immunity, EarlyView.
Tissue‐resident memory T (TRM) cells in barrier tissues provide a frontline defense against invading pathogens. Immune (Signals 1–3) and nutrient (Signal 4) cues play an integral role in directing TRM formation and heterogeneity. The spatial and temporal organization of these signals establishes durable TRM cells across tissues, enabling diverse ...

Intracellular Mono-ADP-Ribosylation in Signaling and Disease

open access: yesCells, 2015
A key process in the regulation of protein activities and thus cellular signaling pathways is the modification of proteins by post-translational mechanisms.

Fine-tuning of Smad protein function by poly(ADP-ribose) polymerases and poly(ADP-ribose) glycohydrolase during transforming growth factor β signaling. [PDF]

open access: yesPLoS ONE, 2014
Initiation, amplitude, duration and termination of transforming growth factor β (TGFβ) signaling via Smad proteins is regulated by post-translational modifications, including phosphorylation, ubiquitination and acetylation.

Dissection of GTPase activating proteins reveals functional asymmetry in the COPI coat of budding yeast. [PDF]

open access: yes, 2019
The Arf GTPase controls formation of the COPI vesicle coat. Recent structural models of COPI revealed the positioning of two Arf1 molecules in contrasting molecular environments.

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

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

open access: yesPLoS 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.

Cool-associated Tyrosine-phosphorylated Protein 1 Is Required for the Anchorage-independent Growth of Cervical Carcinoma Cells by Binding Paxillin and Promoting AKT Activation. [PDF]

open access: yes, 2017
Cool-associated tyrosine-phosphorylated protein 1 (Cat-1) is a signaling scaffold as well as an ADP-ribosylation factor-GTPase-activating protein. Although best known for its role in cell migration, we recently showed that the ability of Cat-1 to bind ...

Profiling of HCAR1 signalling reveals Gαi/o and Gαs activation without β‐arrestin recruitment and the discovery of an allosteric agonist

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Lactate, historically viewed as a metabolic by‐product, has emerged as a signalling molecule via the G protein–coupled receptor Hydroxycarboxylic Acid Receptor 1 (HCAR1). The receptor is primarily expressed in adipocytes but also found in various other tissues.
