A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Photo prise à l'avant (dans la protrusion) d'astrocytes primaires de rat en migration. Marquage par immunofluorescence montrant en rouge, p150 Glued, une protéine associée aux extrémités 'plus' des microtubules et en vert la tubuline des microtubules. La photographie montre l'accumulation de p150 Glued à l'avant des cellules en migration, où la protéine pourrait participer à l'ancrage des microtubules à la membrane plasmique. Pour essayer de corriger, les dérèglements observés lors de la migration des cellules d'astrocytes tumuraux ou gliomes on cherche à connaitre les mécanismes moléculaires fondamentaux qui controlent la polarisation et la migration cellulaires.

Sperm whale myoglobin can be considered as the model protein of the globin family. The pH-dependence of the interactions of apomyoglobin with lipid bilayers shares some similarities with the behavior of pore-forming domains of bacterial toxins belonging also to the globin family. Two different states of apomyoglobin bound to a lipid bilayer have been characterized by using hydrogen/deuterium exchange experiments and mass spectrometry. When bound to the membrane at pH 5.5, apomyoglobin remains mostly native-like and interacts through alpha-helix A. At pH 4, the binding is related to the stabilization of a partially folded state. In that case, alpha-helices A and G are involved in the interaction. At this pH, alpha-helix G, which is the most hydrophobic region of apomyoglobin, is available for interaction with the lipid bilayer because of the loss of the tertiary structure. Our results show the feasibility of such experiments and their potential for the characterization of various membrane-bound states of amphitropic proteins such as pore-forming domains of bacterial toxins. This is not possible with other high-resolution methods, because these proteins are usually in partially folded states when interacting with membranes.
