Advanced Science, EarlyView.In multiple sclerosis, the disruption of the blood‐spinal cord barrier (BSCB) induced by CXCL13 facilitates the infiltration of inflammatory cells into the central nervous system, resulting in demyelination and neuronal injury. Mechanistically, the deleterious impact of CXCL13 on the BSCB is associated with a reduction in tight junction protein ...

Influence of Hydrodynamic Interactions on Mechanical Unfolding of Proteins [PDF]
, 2007 We incorporate hydrodynamic interactions in a structure-based model of ubiquitin and demonstrate that the hydrodynamic coupling may reduce the peak force when stretching the protein at constant speed, especially at larger speeds. Hydrodynamic interactions are also shown to facilitate unfolding at constant force and inhibit stretching by fluid flows.

Atypical Rho GTPases of the RhoBTB Subfamily: Roles in vesicle trafficking and tumorigenesis [PDF]
, 2016 RhoBTB proteins constitute a subfamily of atypical Rho GTPases represented in mammals by RhoBTB1, RhoBTB2, and RhoBTB3. Their characteristic feature is a carboxyl terminal extension that harbors two BTB domains capable of assembling cullin 3-dependent ...

Structure of a HOIP/E2~ubiquitin complex reveals RBR E3 ligase mechanism and regulation
Nature, 2015 Ubiquitination is a central process affecting all facets of cellular signalling and function. A critical step in ubiquitination is the transfer of ubiquitin from an E2 ubiquitin-conjugating enzyme to a substrate or a growing ubiquitin chain, which is ...

Substrates of the BRCA1-dependent ubiquitin ligase [PDF]
Cancer Biology & Therapy, 2006 Discovering the precise function of the breast and ovarian specific tumor suppressor, BRCA1, has proven to be quite complicated. It has been determined that BRCA1, together with BARD1, comprise an E3 ubiquitin ligase. Since it is now known that BRCA1 is an enzyme, the challenge for BRCA1 research is to learn how this enzymatic activity functions in ...

Advanced Science, EarlyView.TRIM25‐mediated ubiquitination of INSIG1 serves as a key driver of lipid metabolism dysregulation in MASH progression. It identifies a novel small‐molecule inhibitor, C27H26N2O4S, which effectively inhibits TRIM25 activity, reducing lipid accumulation and inflammation.

RNF8/UBC13 ubiquitin signaling suppresses synapse formation in the mammalian brain
Nature Communications, 2017 Ubiquitin ligases play critical roles in neuronal connectivity in the brain. Here, Valnegri and colleagues show that ubiquitin ligase RNF8 and ubiquitin-conjugating enzyme UBC13 regulate synapse number in cerebellar granule neurons and rodent cerebellar ...

E3-targetPred: Prediction of E3-Target Proteins Using Deep Latent Space Encoding [PDF]
arXiv, 2020 Understanding E3 ligase and target substrate interactions are important for cell biology and therapeutic development. However, experimental identification of E3 target relationships is not an easy task due to the labor-intensive nature of the experiments. In this article, a sequence-based E3-target prediction model is proposed for the first time.

Syntaxin 17 Translocation Mediated Mitophagy Switching Drives Hyperglycemia‐Induced Vascular Injury
Advanced Science, EarlyView.Mitophagy switching drives high‐glucose‐induced vascular endothelial injury. Short‐term high‐glucose exposure upregulates Fis1 expression and enhances Fis1‐TBC1D15 interaction, activating Parkin‐mediated mitophagy. Long‐term high‐glucose exposure reduces Fis1 expression, inhibiting Parkin‐mediated mitophagy and triggering mitophagy switching from ...

Replication of proto-RNAs sustained by ligase-helicase cycle in oligomer world [PDF]
arXiv, 2013 A mechanism of the replication of proto-RNAs in oligomer world is proposed. The replication is carried out by a minimum cycle which is sustained by a ligase and a helicase. We expect that such a cycle actually worked in the primordial soup and can be constructed in vitro.
