Structural basis for evolutionarily conserved interactions between TFIIS and Paf1C.

The elongation factor TFIIS interacts with Paf1C complex to facilitate processive transcription by Pol II. We here determined the crystal structure of the trypanosoma TFIIS LW domain in a complex with the LFG motif of Leo1, as well as the structures of apo-form TFIIS LW domains from trypanosoma, yeast and human. We revealed that all three TFIIS LW domains possess a conserved hydrophobic core that mediates their interactions with Leo1.

Resonance assignments of the PUB domain of the RNF31 protein.

E3 ubiquitin protein ligase RNF31 is present in human proteins and is involved in linear ubiquitin chain assembly complex (LUBAC) activity and cell growth. RNF31 is involved in ubiquitination, which is the post-translational modification of proteins. Ubiquitin molecules connect with amino acid residues of target proteins under the action of ubiquitin-activating enzyme E1, ubiquitin binding enzyme E2 and ubiquitin ligase E3, so as to achieve certain physiological functions.

Associations of depression score with metabolic dysfunction-associated fatty liver disease and liver fibrosis.

Background: Growing evidence suggests a link between depression and nonalcoholic fatty liver disease (NAFLD). Recently, a change from NAFLD to metabolic dysfunction-associated fatty liver disease (MAFLD) has been proposed. The aim of this study was to determine whether depression scores are associated with newly defined MAFLD as well as liver fibrosis in the US general population.

Deafness-Associated ADGRV1 Mutation Impairs USH2A Stability through Improper Phosphorylation of WHRN and WDSUB1 Recruitment.

The ankle-link complex (ALC) consists of USH2A, WHRN, PDZD7, and ADGRV1 and plays an important role in hair cell development. At present, its architectural organization and signaling role remain unclear. By establishing Adgrv1 Y6236fsX1 mutant mice as a model of the deafness-associated human Y6244fsX1 mutation, the authors show here that the Y6236fsX1 mutation disrupts the interaction between adhesion G protein-coupled receptor V subfamily member 1 (ADGRV1) and other ALC components, resulting in stereocilia disorganization and mechanoelectrical transduction (MET) deficits.

Review of the epidemiology, pathogenesis and prevention of atrial fibrillation after pacemaker implantation.

Cardiac pacemaker implantation is an important treatment for symptomatic bradycardia. However, epidemiological data show that the incidence of atrial fibrillation (AF) is significantly higher in patients with implanted pacemakers than in the general population, which may be related to the preoperative presence of multiple risk factors for AF, improvement of diagnostic sensitivity and the pacemaker itself. The pathogenesis of AF after the implantation of pacemaker is related to cardiac electrical remodeling, structural remodeling, inflammation, and autonomic nervous disorder, which are induced by the pacemaker.

Blood Donation Fear, Perceived Rewards, Self-Efficacy, and Intention to Return Among Whole Blood Donors in China: A Social Cognitive Perspective.

With the increasing demand from aging population and seasonal blood shortage, recruiting and retaining blood donors has become an urgent issue for the blood collection centers in China. This study aims to understand intention to donate again from a social cognitive perspective among whole blood donors in China through investigating the association between the blood donation fear, perceived rewards, self-efficacy, and intention to return. A cross-sectional survey was conducted in six cities, which are geographically and socioeconomically distinct areas in Jiangsu, China.

Molecular basis for arginine C-terminal degron recognition by Cul2 E3 ligase.

Degrons are elements within protein substrates that mediate the interaction with specific degradation machineries to control proteolysis. Recently, a few classes of C-terminal degrons (C-degrons) that are recognized by dedicated cullin-RING ligases (CRLs) have been identified. Specifically, CRL2 using the related substrate adapters FEM1A/B/C was found to recognize C degrons ending with arginine (Arg/C-degron).

Halophilic to mesophilic adaptation of ubiquitin-like proteins.

Elucidating how proteins adapt from halophilic to mesophilic environments will enable a better understanding of protein evolution and folding. In this study, by directed evolution and site-directed mutagenesis of the halophilic ubiquitin-like protein (ULP) Samp2, we find that substitution of the prebiotic amino acid Asp31 by Gly is uniquely effective in the mesophilic adaptation of ULP. Sequence analysis shows that substitution of Asp/Glu in halophilic ULPs by Gly in mesophilic ULPs has higher occurrence than other substitutions, supporting the unique role of the substitution in the mesophilic adaptation of ULP.
