  • to retain selectivity it is therefore important to use the lowest effective dose. (nih.gov)
  • Proteins are an important building block of life and are vital for almost every process that keeps cells alive. (elifesciences.org)
  • Yet, these proteins play important roles in many processes that require the protein to interact with a number of other proteins. (elifesciences.org)
  • Vasopressin (VP) and oxytocin (OT) are cyclic neuropeptides that regulate fundamental physiological functions via four G protein-coupled receptors, V 1a R, V 1b R, V 2 R, and OTR. (rsc.org)
  • True mirror planes and centres of symmetry are of course forbidden because proteins consist only of L-amino acids. (nih.gov)
  • Silk is 97% composed of proteins, 3% of fats and waxes, as well as 18 amino acids that positively affect human skin metabolism. (sakura-line.com)
  • The two most crucial protein machineries involved in this process are reaction center and light harvesting complexes. (wustl.edu)
  • They are usually giant protein complexes with different numbers of co-factors. (wustl.edu)
  • It forms a non-living, replacement vessel that retains the physical and mechanical integrity of a human blood vessel. (nih.gov)
  • Structural diversity of leucine-rich repeat proteins. (embl.de)
  • Earlier this year, the VRC team obtained atomic-level details of an RSV protein - called the fusion (F) glycoprotein - bound to a broadly neutralizing human RSV antibody. (nih.gov)
  • In their current publication, Drs. Kwong and Graham describe how they used this structural information to design and engineer F glycoprotein variants that retained antigenic site zero even when no antibody was bound to it. (nih.gov)
  • A relatively constant percentage of synthetic glucocorticoids is bound to plasma proteins, and, because this percentage is concentration independent, the rate of metabolic clearance remains constant for synthetic glucocorticoids, regardless of dose. (medscape.com)
  • Also acts a structural subunit of various enzymes such as prolyl 4-hydroxylase and microsomal triacylglycerol transfer protein MTTP. (nih.gov)
  • Expression of these proteins is spatially and temporally regulated during embryonic development. (cancerindex.org)
  • In biophysical applications, this amounts to describing a biomolecule, such as a protein, using a number of constituent units, called CG sites, lower than the number of particles composing the original, atomistic system. (frontiersin.org)
  • In this article we focused on their high expressivity and explored the factors contributing for that and their relevance in the milieu of protein sequence evolution. (biomedcentral.com)
  • Despite the rapid progress of protein residue contact prediction, predicted residue contact maps frequently contain many errors. (biomedcentral.com)
  • Starting from the predicted contact map of CCMpred, RDb 2 C remarkably outperforms all state-of-the-art methods on two conventional test sets of β proteins (BetaSheet916 and BetaSheet1452), and achieves F1-scores of ~ 62% and ~ 76% at the residue level and strand level, respectively.
