摘要:Numerous proteins display pleiotropic functions in different clinical contexts. However, the molecular mechanism underlying such effects is rarely understood. Speckle-type POZ protein (SPOP) is a typical example, exhibiting tumor-suppressing or tumor-promoting effects in different tumor types in accordance with different amino acid changes; specifically, two distinct sets of variants in SPOP are commonly found in subsets of prostate cancer and endometrial cancer patients. To comprehensively ch...

摘要:Bread wheat (Triticum aestivum L.) is the most popular wheat species in the world today. However, studies on the domestication of wheat have rarely focused on the evolution of this specific species of Triticum. The discussions that have emerged have focused on the evolution of bread wheat, revealing it to have emerged from the hybridization of an already domesticated free-threshing wheat and the wild goatgrass known as Aegilops tauschii Coss. These studies, however, have focused on the previou...

摘要:Determination of specimen structure from cryoelectron microscopy (cryo-EM) experiments relies on an accurate model of the electrostatic potential of the specimen. For biological macromolecules, the potential is strongly influenced by the presence of chemical bonds between atoms, a fact unaccounted for by models of electron scattering that are currently standard in the field. We propose a Bayesian approach to the estimation of atomic scattering factors which incorporates the effect of the molec...

摘要:Soil inorganic carbon (SIC) constitutes half of the terrestrial carbon pool and exerts a profound influence on global carbon cycling and ecosystem multifunctionality. Contrary to the view of millennial-scale stability, SIC in cropland are undergoing rapid changes due to intense anthropogenic disturbances. However, the direction, magnitude, and drivers of SIC changes over recent decades remain poorly quantified, especially in entire soil profile. Here, we quantified changes in SIC across a 1-m ...

摘要:Enveloped viruses enter cells by membrane fusion. The viral membrane fuses with a host membrane, either at the cell surface or within endocytic compartments. For endocytic entry, fusion is typically triggered by low pH and often requires proteolytic priming by compartment-specific host proteases, which together define the site and mechanism of fusion and shape viral tropism. Inhibition of the lipid kinase PIKfyve, which generates PI(5)P and PI(3,5)P2 in late endosomes and lysosomes, swells tho...

摘要:In this paper, we explore whether different choice environments affect voters' willingness to put democracy over party and policy. Using a series of candidate choice experiments in which we manipulate not only candidate attributes, but also the number of races on the ballot, we find that when voters are able to vote in multiple races on a ballot they are substantially more likely to punish antidemocratic candidates than when they are only given the opportunity to cast one vote. We refer to thi...

摘要:Ribonucleotide reductases (RNRs) catalyze the conversion of ribonucleotide (RNA) to deoxyribonucleotide (DNA) building blocks initiated by a long-range (>30 & Aring;) proton-coupled electron transfer (PCET) by mechanistic principles that remain much debated. By combining multiscale quantum and classical simulations with directed mutagenesis, X-ray crystallography, and vibrational and electron paramagnetic resonance spectroscopy, we elucidate here the molecular principles underlying how metal-f...

摘要:Inflammasome activation triggers caspase-1-dependent maturation of pro-interleukin-1 beta (pro-IL-1 beta) in an apoptosis-associated speck-like protein containing a CARD (ASC)-dependent manner, yet the mechanism by which pro-IL-1 beta is physically recruited to the ASC signaling platform has remained undefined. Here, we identify the ASC linker domain (ASCLD) as a noncanonical protein-interaction interface, that can directly recruits pro-IL-1 beta onto the ASC speck. Using a live-cell NanoBRET ...

摘要:People must often sustain cognitive effort to achieve important goals. Although current models recognize that subcortical valuation regions are important for initiating such effort, they have not seen them as playing meaningful roles in sustaining effort throughout task performance. Here, we demonstrate that core subcortical valuation regions-the basolateral amygdala (BLA) and nucleus accumbens (NAcc)-contribute to sustaining cognitive effort on a challenging working memory task. First, conver...
