  • His interest in cell adherence was sparked, and he moved on to examine attachment in other conditions such as in the presence of protein, magnesium, and calcium. (wikipedia.org)
  • The ectodomain of this protein mediates bacterial adhesion to mammalian cells, and the cytoplasmic domain is required for internalization. (wikipedia.org)
  • The RhoA activation assay was tested by loading the RhoA protein in cell lysates with either GTPγS or GDP. (cytoskeleton.com)
  • This process depends on the general physico-chemical features of the cargo membrane protein and on the interactions of these features with the collective properties of the bilayer, instead of the one-to-one intermolecular interactions that exist between discrete signals and their receptors.
