Simulation and Visualization of Dynamics in RNA·protein Complexes in Translation
… rRNA signatures and signatures in the ribosomal proteins (r-proteins) show that the rRNA signatures coevolved with both domain specific r-proteins and inserts in universal r-proteins. The largest bacterial structural rRNA signature with such a coevolutionary protein partner is found in the …

Some properties and function of ribosomal proteins from the seeds of Pinus lambertiana
Functional roles of ribosomal proteins (r-proteins) on the structural properties of ribosomes from Pinus lambertiana were studied. For this purpose, r-proteins in the ribosome were dansylated with dansyl chloride (l-dimethylaminonaphthalene-5-sulfonyl chloride) dispersed on celite (DNS-Cl-celite); …

The Nucleolar Protein Nucleophosmin Undergoes Liquid-Liquid Phase Separation with Arginine-Rich Nucleolar Proteins through Weak, Multivalent Electrostatic Interactions
… multivalency and mediate interactions with proteins that contain multiple arginine-rich motifs (R-proteins). Using a variety of techniques, we have identified several nucleolar R-proteins which bind to and phase separate with NPM1. Here we show that the liquid-like properties of NPM1 …

Toward the understanding of TIR-NB-LRR–mediated immunity; study of the AvrRps4 recognition model in Arabidopsis
… and is mainly mediated by NB-LRR resistance (R) proteins. However, the mechanisms by which NB-LRR proteins recognize effectors and induce downstream signaling events are poorly known. This PhD work focused on the characterization of TIR-NB-LRR–mediated immnunity in plants. In Arabidopsis, two …

Histone Variant H2A.Z Substitution Mediated by the SWR1-like Complex is a Novel Transcriptional Regulatory Mechanism Controlling Defense Genes and Immunity in Plants
… responses in plants involves resistance (R) proteins, which detect the presence of effector molecules from pathogens and trigger a large-scale reprogramming in RNA transcription of defense genes. MORC1 is one of few proteins that have been shown to interact with several of these R-proteins …

Dissecting Transcriptional Regulation of Rpp8 in Arabidopsis thaliana
… pathogens. Inducible responses are mediated by R proteins, which recognize invading pathogens. R proteins must be precisely regulated to provide effective resistance, without inhibiting normal plant growth. However, little is known about R gene regulation under defense-inducing conditions. The …

Ribosomal protein mutants and their effects on plant growth and development
… of four rRNAs and approximately 80 ribosomal proteins (r-proteins). R-proteins are encoded by gene families with large families (average of twelve members) predominating in mammals and smaller families (two to seven members) in plants. Increased ribosome heterogeneity is possible in plant …

The Development and Application of Methods to Study the Evolution of Specificity, Allostery, and RNA -Protein Interactions in Translation
… We present evidence that domain specific r-proteins and signatures in universal r-proteins have coevolved with rRNA signatures, which are often in close proximity. We have combined equilibrium and steered molecular dynamics (SMD) simulations with principal component and correlation analyses …

Simulation and visualization of dynamics in RNA-protein complexes in translation
… information and synthesizing the corresponding proteins, is universal and found throughout the three domains of life. The flow of information in translation involves a series of distinct but highly conserved RNA·protein complexes with the ribosome being the largest ribonucleoprotein complex in …

DISCOVERY AND FUNCTIONAL ANALYSES OF HESSIAN FLY EFFECTOR-ENCODING GENES
… insects. The Hessian fly uses secreted effector proteins to control susceptible host plant physiology, transforming the plant cells in a nutritive tissue to support the developing insect larva. HF-resistant wheat cultivars employ resistance (R) proteins to perceive the insect avirulence effectors …

REGULATION OF DEFENSE RESPONSES MEDIATED BY BON1 AND BAP2 IN ARABIDOPSIS THALIANA
… latter case, the plant cell perceives foreign proteins and this triggers the hypersensitive response (HR), a programmed cell death (PCD) to prevent further spread of the pathogen. This is mediated by the recognition of specific avirulence (Avr) proteins from the pathogen by resistance (R) …

Structural basis for interactions of the Phytophthora sojae RxLR effector Avh5 with phosphatidylinositol 3-phosphate and for host cell entry
… effectors via intracellular receptors (R proteins) that form part of their defense system. Entry of some effector proteins into plant cells is mediated by conserved RxLR motifs in the effectors and phosphoinositides (PIPs) resident in the host plasma membrane such as phosphatidylinositol …

Molecular recognition in plant immunity
… disease-resistance genes, which generally encode proteins with nucleotide-binding and leucine-rich repeat domains (NB-LRRs). NB-LRRs are a large of proteins found in both plants and animals, with plant NB-LRRs further classified by the presence of N-terminal coiled-coil or toll-interleukin …

The origin and evolution of the ribosome

Identifying loci conferring quantitative disease resistance in sorghum and maize against fungal foliar pathogens
… complete resistance against the pathogen. R proteins can interact directly as receptors or indirectly as guardees/decoys with pathogen Avr proteins. R genes are generally race specific. Quantitative disease resistance (QDR) is genetically complex with a partial phenotype conferred by multiple …

Evolution and assembly of the ribosome
