Confronting the catalytic dark matter encoded by sequenced genomes
The post-genomic era has provided researchers with a deluge of protein sequences. However, a significant fraction of the proteins encoded by sequenced genomes remains without an identified function. Here, we aim at determining how many enzymes of uncertain or unknown function are still present in the Saccharomyces cerevisiae and human proteomes. Using information available in the Swiss-Prot, BR...
متن کاملOligodendrocyte-Encoded HIF Function Couples Postnatal Myelination and White Matter Angiogenesis
Myelin sheaths provide critical functional and trophic support for axons in white matter tracts of the brain. Oligodendrocyte precursor cells (OPCs) have extraordinary metabolic requirements during development as they differentiate to produce multiple myelin segments, implying that they must first secure adequate access to blood supply. However, mechanisms that coordinate myelination and angiog...
متن کاملLegacy of Rice Roots as Encoded in Distinctive Microsites of Oxides, Silicates, and Organic Matter
Rice (Oryza sativa) is usually grown under flooded conditions, leading to anoxic periods in the soil. Rice plants transport oxygen via aerenchyma from the atmosphere to the roots. Driven by O2 release into the rhizosphere, radial gradients of ferric Fe and co-precipitated organic substances are formed. Our study aimed at elucidating the composition and spatial extension of those gradients. Air-...
متن کاملWhen minds matter for moral judgment: intent information is neurally encoded for harmful but not impure acts.
Recent behavioral evidence indicates a key role for intent in moral judgments of harmful acts (e.g. assault) but not impure acts (e.g. incest). We tested whether the neural responses in regions for mental state reasoning, including the right temporoparietal junction (RTPJ), are greater when people evaluate harmful vs impure violations. In addition, using multivoxel pattern analysis, we investig...
متن کاملGenetically encoded fluorescent tags
Genetically encoded fluorescent tags are protein sequences that can be fused to a protein of interest to render it fluorescent. These tags have revolutionized cell biology by allowing nearly any protein to be imaged by light microscopy at submicrometer spatial resolution and subsecond time resolution in a live cell or organism. They can also be used to measure protein abundance in thousands to ...
