Open Targets Genetics (https://genetics.opentargets.org) is an open-access integrative resource that aggregates human GWAS and functional genomics data including gene expression, protein abundance, chromatin interaction conformation from a wide range of cell types tissues to make robust connections between GWAS-associated loci, variants likely causal genes. This enables systematic identification prioritisation genes across all published trait-associated loci. In this paper, we describe the...

The Open Targets Platform (https://www.targetvalidation.org/) provides users with a queryable knowledgebase and user interface to aid systematic target identification prioritisation for drug discovery based upon underlying evidence. It is publicly available the code open source. Since our last update two years ago, we have had 10 releases maintain continuously improve evidence target-disease relationships from 20 different data sources. In addition, integrated new key datasets, including...

Abstract The current wealth of genomic variation data identified at nucleotide level presents the challenge understanding by which mechanisms amino acid affects cellular processes. These effects may manifest as distinct phenotypic differences between individuals or result in development disease. Physical interactions molecules are linking steps underlying most, if not all, Understanding that sequence has on a molecule’s is key step towards connecting mechanistic characterization...

Interacting proteins tend to have similar functions, influencing the same organismal traits. Interaction networks can be used expand list of candidate trait-associated genes from genome-wide association studies. Here, we performed network-based expansion for 1,002 human traits showing that this recovers known disease or drug targets. The similarity network scores identifies groups likely share an underlying genetic and biological process. We identified 73 pleiotropic gene modules linked...

Abstract The coordinated regulation of protein kinases is a rapid mechanism that integrates diverse cues and swiftly determines appropriate cellular responses. However, our understanding decision‐making has been limited by the small number simultaneously monitored phospho‐regulatory events. Here, we have estimated changes in activity 215 human 399 conditions derived from large compilation phosphopeptide quantifications. This atlas identifies commonly regulated as those are central signaling...

Many drug discovery projects are started but few progress fully through clinical trials to approval. Previous work has shown that human genetics support for the therapeutic hypothesis increases chance of trial progression. Here, we applied natural language processing classify free-text reasons 28,561 stopped before their endpoints were met. We then evaluated these classes in light underlying evidence and target properties. found more likely stop because a lack efficacy absence strong genetic...

Phosphoproteomic experiments are increasingly used to study the changes in signaling occurring across different conditions. It has been proposed that phosphorylation of kinase target sites can be infer when a activity is under regulation. However, these approaches have not yet benchmarked due lack appropriate benchmarking strategies.We curated phosphoproteomic and gold standard dataset containing total 184 kinase-condition pairs where regulation expected occur benchmark compare inference...

Three cDNA clones isolated from Syrian hamster cells (p4F1, p2F1, and p2A9) contain sequences that are preferentially expressed in the G1 phase of cell cycle. The expression these was investigated human peripheral blood normal individuals patients with leukemia. p4F1 p2F1 is clearly dependent on cycle mononuclear stimulated to proliferate phytohemagglutinin; p2A9 cannot be detected lymphocytes but a cell-cycle-dependent manner diploid fibroblasts (WI-38). These genes also show different...

Abstract Protein phosphorylation is the best characterized post-translational modification that regulates almost all cellular processes through diverse mechanisms such as changing protein conformations, interactions, and localization. While inventory for sites across different species has rapidly expanded, their functional role remains poorly investigated. Here, we combine 537,321 phosphosites from 40 eukaryotic to identify highly conserved hotspot regions within domain families. Mapping...
