Initial phylogenomic analysis of three super-clades (S, V, and G) isolated from the outbreaks of distinct geographic locations (China, USA and Europe) within SARS-CoV-2 showed little evidence of local/regional adaptation, suggesting instead that viral evolution is mainly driven by genetic drift and founder events 7 .

The yeast YPxL motif binds to a hydrophobic groove in the central V-domain of yeast proteins Bro1 and Rim20 (Alix_V domain-containing proteins), which are implicated in vacuolar transport and the pH response respectively. (eu.org)

We conclude that association of Us9 with lipid rafts is key for efficient targeting of structural proteins to axons and, as a consequence, for directional spread of PRV from pre-synaptic to post-synaptic neurons and cells of the mammalian nervous system. (princeton.edu)
One example is syncytin , a retroviral protein used for the construction of the mammalian placenta. (virology.ws)

EBNA3C is an EBV-encoded nuclear protein, essential for proliferation of EBV infected B-lymphocytes. (scienceopen.com)

In parallel to our commitment to provide a comprehensive beamline portfolio for integrative structural determination, we are continuing to develop an ambitious in-house research programme, which helps us to assist our user community needs by providing expertise and experience in sample preparation and characterisation, and advanced synchrotron tools. (esrf.fr)
The work presented in this chapter represents only a very small fraction of the science reported by the Structural Biology user community, but it illustrates the trends observed in recent years towards the application of integrative structural biology to unravel major fundamental biology challenges. (esrf.fr)

these proteins also elicit case-patients who had received 2 doses of Rotarix, type-specific and cross-reactive neutralizing antibody and specimen SA179 was collected from a case-patient responses ( 1 ). (cdc.gov)

Launch Translation of mRNAs by eukaryotic cells is Timosaponin b-II certainly a complicated energy-dependent process that may be quickly suppressed in response to mobile stressors such as for example negative energy stability starvation growth aspect withdrawal hypoxia proteins misfolding and viral contamination (reviewed in reference 1). (biongenex.com)
We know that viral proteins can be returned to cells, where they serve useful functions. (virology.ws)
The main lines of our work are 1) reconstitution of the process with more than 50 pure proteins and mechanistic analysis, 2) structure determination of the 50 protein complex at atomic resolution, and 3) studies of chromatin remodelling, required for transcription of the DNA template in living cells. (stanford.edu)
When expressed as a recombinant protein in transfected cells, PV 3A cofractionates with endoplasmic reticulum markers ( 66 ), and its single transient expression can disrupt the secretory apparatus ( 23 ) and decrease major histocompatibility complex (MHC) class I expression ( 22 ). (asm.org)
The carboxyl-terminal 64 aa of gamma(1)34.5 protein are homologous to the corresponding domain of MyD116, the murine growth arrest and DNA damage gene 34 (GADD34) protein and the two domains are functionally interchangeable in infected cells. (scienceopen.com)
The GADD34 protein may have a similar function in eukaryotic cells. (scienceopen.com)
Moreover, we show that fusogens from multiple viral families are compatible with DIRECTED and that DIRECTED components can target multiple delivery chassis (e.g., lentivirus and MMLV gag) to specific cell types, including primary human T cells in PBMCs and whole blood. (bvsalud.org)
The TTN gene provides instructions for making a protein called titin, which is found in the sarcomeres of many types of muscle cells, including cardiomyocytes. (medlineplus.gov)

studies revealed that active translation occurs within VF and that ribosomal subunits and proteins required for translation initiation elongation termination and recycling localize to the factory. (biongenex.com)

His main interests are on the mechanisms of transmembrane signal instigation with a particular focus on G protein-coupled receptors and cytokine receptors. (stanford.edu)

A very common motif among viral capsid proteins is called the single jelly roll , made up of eight beta strands in two four-stranded sheets. (virology.ws)
The link between the LYPxL motif and ESCRT was then established by identifying the ESCRT-associated protein Alix as a binding partner of LYPxL ( Strack,2003 ). (eu.org)

The N-terminal helix and the hinge that connects it to the transmembrane helix are significantly more dynamic than the rest of the protein, thus facilitating structural rearrangement during bacteriophage assembly. (rcsb.org)

Depending on the specific biological question being asked, methods for protein-protein interface comparison with different focuses have been developed. (biomedcentral.com)
