  • As an example, the interaction of the SARS-CoV-2 programmed ribosomal frameshifting element with the trans-acting factor short isoform of zinc-finger antiviral protein is elaborated. (helmholtz-hzi.de)
  • Pathologically, FXTAS is characterized by ubiquitin-positive intranuclear neuronal inclusions, raising the possibility that failure of protein quality control pathways could contribute to disease pathogenesis. (sdbonline.org)
  • Impairment of protein quality control pathways is a common feature among almost all neurodegenerative conditions, including Alzheimer's disease, Parkinson's disease, polyglutamine diseases and ALS/frontotemporal dementia. (sdbonline.org)
  • Together, these conditions have been referred to as neurodegenerative proteinopathies, implying that failures in protein quality control pathways are a proximal shared event in disease pathogenesis and thus a potentially shared route to effective therapeutics. (sdbonline.org)
  • Further validation of three of the identified proteins provided new insights into specific pathways and processes related to plant immunity where AtNHR2A and AtNHR2B participate. (frontiersin.org)
  • The mHTT protein influences a plethora of cellular processes including transcription, axonal transport, cytoskeletal structure/function, signal transduction, and autophagy that ultimately result in cell death. (nature.com)
  • We are obtaining detailed atomic descriptions of the proteins, connecting their structural chemistry with their cellular function in healthy human beings, and trying to understand how structural and functional aberrations are linked to human diseases. (nih.gov)
  • Finally, we investigate the spatio-temporal stress signaling, revealing cellular relocation of ribosomal proteins in response to hypertonicity and muscle contraction. (nature.com)
  • to others, the microsomes consist of protein and lipid contaminated by particles. (wikipedia.org)
  • This is the first study to demonstrate regulation of CBs by ribosomal proteins. (yale.edu)
  • Both proteins showed up-regulation at mRNA as well as at protein level following MPA exposure.MLC2 is known to be involved in several functions including tight junctions (TJ) regulation. (uni-goettingen.de)
  • To characterize the dynamics of growth factor signaling, Mann stimulated isotope-tagged batches of cells with EGF for different time intervals and analyzed the combined lysate using mass spectrometry. (the-scientist.com)
  • Current techniques of Metabolomics and Bioanalytics including quantitative metabolite analysis methods (chromatography, mass spectrometry) are applied for comprehensive gene function- or stress response analyses. (uni-wuerzburg.de)
  • Because the detailed functions of AtNHR2A and AtNHR2B are still unknown, the main objective of this work is to gain insight into their function by investigating their respective protein-protein interaction network (interactome). (frontiersin.org)
  • For the protein interaction network, glyceraldehyde-3-phosphate dehydrogenase of the down-regulated proteins was postulated to be the key factor affecting the entire metabolic system or signal transduction pathway. (scielo.br)
