• The receptor has high affinity (KD, 174 pM) for human IFN alpha and, unlike other type I IFN receptors, has broad species specificity, binding to human, rabbit, bovine, rat, and mouse type I IFNs. (nih.gov)
  • These results suggest that discrete mutations that narrow the specificity of more broadly responsive sex pheromone receptors may provide a mechanism that contributes to speciation. (pnas.org)

  • SAR, species specificity, and cellular activity of cyclopentene dicarboxylic acid amides as DHODH inhibitors. (nih.gov)
  • Activities on human, rat, and mouse enzymes indicate a species specificity of these inhibitors. (nih.gov)
  • The results suggest that the development of species-specific inhibitors of DHDPS as potential antibacterials is achievable. (edu.au)
  • As this field progresses, this synthesis of functional biology and evolutionary studies will provide insight into the molecular basis of the species barriers that maintain the enormous diversity seen in flowering plants. (valpo.edu)
  • Niche differentiation with respect to habitat has been hypothesized to shape patterns of diversity and species distributions in plant communities. (springer.com)
  • Species composition and diversity varied along the topographical gradient from low flat to ridge top habitats. (springer.com)
  • The low depression and low flat habitats were characterized by high diversity and similar species composition, relative to slopes, high gullies and ridge tops. (springer.com)
  • The large number of species-habitat associations and the pronounced contrast between low (valley) and elevated (ridgetop) habitats in the Korup plot shows that niche differentiation with respect to edaphic variables (e.g., soil moisture, nutrients) contributes to local scale tree species distributions and to the maintenance of diversity in African forests.

  • In this Review, we examine the host barriers that influenza A viruses of animals, especially birds, must overcome to initiate a pandemic in humans and describe how, on crossing the species barrier, the virus mutates to establish new interactions with the human host. (flu.org.cn)
  • Two human GPI-T signal sequences were also tested and each showed diminished extracellular INV activity, consistent with lower levels of GPI anchoring and species specificity. (portlandpress.com)
  • Evolution of the immunologic species specificity of human serum proteins. (semanticscholar.org)
  • The species specificity maps to the LFA-1 alpha subunit, because mouse x human hybrid cells expressing the human alpha subunit associated with a mouse beta subunit bind to human ICAM-1, whereas those with a human beta subunit associated with a murine alpha subunit do not. (ox.ac.uk)
