Clinical implication and immunological characterisation of the ARF-GEF family member CYTH4 in ovarian cancer

Autoimmunity, 2020
Background The GTP exchange factors on ADP-ribosylation factor (ARF) mediate the GDP/GTP exchange on ARF, serve as regulators in protein trafficking and membrane dynamics, and play critical roles in various cell processes.

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 ...

ADP-ribosylation factors: a family of ~20-kDa guanine nucleotide-binding proteins that activate cholera toxin

, 1994
ADP-ribosylation factors (ARFs) comprise a family of ∼20 kDa guanine nucleotide-binding proteins that were discovered as one of several cofactors required in cholera toxin-catalyzed ADP-ribosylation of Gsα, the guanine nucleotide-binding protein ...

Clostridial binary toxins: iota and C2 family portraits

Frontiers in Cellular and Infection Microbiology, 2011
There are many pathogenic Clostridium species with diverse virulence factors that include protein toxins. Some of these bacteria, such as C. botulinum, C. difficile, C. perfringens and C. spiroforme, cause enteric problems in animals as well as humans.

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.

Auxin‐related regulation of barley floral organ fate: genetic and phenotypic insights from tweaky spike mutants

New Phytologist, EarlyView.
Inflorescence/floret phenotypes of tweaky spike (tw) barley (Hordeum vulgare) mutants and their respective WT backgrounds. Summary Mutant‐based research is a cornerstone for elucidating gene function in barley (Hordeum vulgare) and other cereals. In this study, we exploited a unique collection of barley tweaky spike (tw) mutants to identify the locus ...

Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

Maternal protein restriction programs the ageing kidney: Proteomic signatures of early‐life origin renal and metabolic dysfunction

The Journal of Physiology, EarlyView.
Abstract figure legend Maternal protein restriction (MPR) induced persistent renal histopathological alterations accompanied by elevated serum creatinine levels. Nephron‐segment proteomic analysis revealed region‐specific molecular dysregulation affecting Bowman's capsule (PARK7, oxidative stress sensor; MSN, cytoskeletal organization), the proximal ...

The Guanine Nucleotide Exchange Factor ARNO mediates the activation of ARF and phospholipase D by insulin

BMC Cell Biology, 2003
Background Phospholipase D (PLD) is involved in many signaling pathways. In most systems, the activity of PLD is primarily regulated by the members of the ADP-Ribosylation Factor (ARF) family of GTPases, but the mechanism of activation of PLD and ARF by ...
