Serine 298 Phosphorylation in Linker 2 of UHRF1 Regulates Ligand-Binding Property of Its Tandem Tudor Domain

Ubiquitin-like with PHD and RING finger domains 1 (UHRF1) is an essential factor for the maintenance of mammalian DNA methylation and harbors several reader modules for recognizing epigenetic marks. The tandem Tudor domain (TTD) of UHRF1 has a peptide-binding groove that functions as a binding platform for intra- or intermolecular interactions. Besides the groove interacting with unphosphorylated linker 2 and spacer of UHRF1, it also interacts with di/tri-methylated histone H3 at Lys9 and DNA ligase 1 (LIG1) at Lys126. Here we focus on the phosphorylation of Ser298 in linker 2, which was implied to regulate the ligand-binding property of the TTD.

Pushing property limits in materials discovery via boundless objective-free exploration

Materials chemists develop chemical compounds to meet often conflicting demands of industrial applications. This process may not be properly modeled by black-box optimization because the target property is not well defined in some cases. Herein, we propose a new algorithm for automated materials discovery called BoundLess Objective-free eXploration (BLOX) that uses a novel criterion based on kernel-based Stein discrepancy in the property space.

Transplantation of fetal liver tissue coated by ultra-purified alginate gel over liver improves hepatic function in the cirrhosis rat model

In this study, we used a new coating agent, that is, ultra-purified alginate gel (UPAL), for fetal liver tissue transplantation. This study aims to compare the effect of UPAL with the effect of other coating agents on improving the effect of fetal liver tissue transplantation in a liver cirrhosis rat model.

Genome-Wide Association Study in Asians Identifies Novel Loci for High Myopia and Highlights a Nervous System Role in Its Pathogenesis

We identified 9 loci with genome-wide significance (P < 5.0 × 10–8). Three loci were previously reported myopia-related loci (ZC3H11B on 1q41, GJD2 on 15q14, and RASGRF1 on 15q25.1), and the other 6 were novel (HIVEP3 on 1p34.2, NFASC/CNTN2 on 1q32.1, CNTN4/CNTN6 on 3p26.3, FRMD4B on 3p14.1, LINC02418 on 12q24.33, and AKAP13 on 15q25.3). The GO analysis revealed a significant role of the nervous system related to synaptic signaling, neuronal development, and Ras/Rho signaling in the pathogenesis of high myopia.
