摘要:As structural biology and drug discovery depend on high-quality protein structures, assessment tools are essential. We describe a new method for validating amino-acid conformations: PhiSiCal ( tpyix al) Checkup. Twenty new joint probability distributions in the form of statistical mixture models explain the empirical distributions of dihedral angles (0), tp , yi , x 1 , x 2 , ...) of canonical amino acids in experimental protein structures. Marginal and conditional probability distributions fo...

摘要:The Atlantic Meridional Overturning Circulation (AMOC) is a key component of the global climate that is projected to weaken under future anthropogenic climate change. While many studies have investigated the AMOC's response to different levels and types of forcing in climate models, relatively little attention has been paid to the AMOC's sensitivity to the rate of forcing change, despite it also being highly uncertain in future emissions scenarios. In this study, I isolate the AMOC's response ...

摘要:Tsg101 is a highly conserved protein best known as an early- functioning component of cellular ESCRT machinery participating in recognition, sorting, and trafficking of cellular cargo to various intracellular destinations. It shares sequence and structural homology to canonical ubiquitin- conjugating (E2) enzymes and is linked to diverse events regulated by Ub signaling. How it might fulfill these roles is unclear. Here, we show that Tsg101 E2 mimicry permits interactions with diverse ubiquiti...

摘要:to and precisely follow very fast cycle-by-cycle fluctuations in the phase of sounddriven cochlear vibrations. Yet, the perceptual role of this temporal fine structure experimentally manipulate TFS cues without altering other perceptually relevant cues. Here, we circumnavigated this limitation by leveraging individual differences across 200 participants to systematically compare variations in TFS sensitivity to performance in a range of speech perception tasks. TFS sensitivity was assessed thr...

摘要:In species with genetic sex determination (GSD), the sex identity of the soma determines germ cell fate. For example, in mice, XY germ cells that enter an ovary differentiate as oogonia, whereas XX germ cells that enter a testis initiate differentiation as spermatogonia. However, numerous species lack a GSD system and instead display temperature- dependent sex determination (TSD). In the red- eared slider turtle, Trachemys scripta, a TSD model species with a warm female promoting temperature (...

摘要:Biophysical constraints limit the specificity with which transcription factors (TFs) can target regulatory DNA. While individual nontarget binding events may be low affinity, the sheer number of such interactions could present a challenge for gene regulation by degrading its precision or possibly leading to an erroneous induction state. Chromatin can prevent nontarget binding by rendering DNA physically inaccessible to TFs, at the cost of energy-consuming remodeling orchestrated by pioneer fac...

摘要:The Qin and Western Han dynasties (221 BCE to 24 CE) represent an era of societal prosperity in China. However, due to a lack of high- resolution paleoclimate records it is still unclear whether the agricultural boost documented for this period was associated with more favorable climatic conditions. Here, multiparameter analysis of annually resolved tree- ring records and process- based physiological modeling provide evidence of stable and consistently humid climatic conditions during 270 to 7...

摘要:Heterozygotic GATA6 mutations are responsible for various congenital diseases in the heart, pancreas, liver, and other organs in humans. However, there is lack of an animal that can comprehensively model these diseases since GATA6 is essential for early embryogenesis. Here, we report the establishment of a gata6 knockout zebrafish which recapitulates most of the symptoms in patients with GATA6 mutations, including cardiac outflow tract defects, pancreatic hypoplasia/agenesis, gallbladder agene...

摘要:Host plants and various fungicides inhibit plant pathogens by inducing the release of excessive reactive oxygen species (ROS) and causing DNA damage, either directly or indirectly leading to cell death. The mechanisms by which the oomycete Phytophthora sojae manages ROS stress resulting from plant immune responses and fungicides remains unclear. This study elucidates the role of histone acetylation in ROS- induced DNA damage responses (DDR) to adapt to stress. Mechanistically, the P. sojae DNA...
