    A random cell motility gradient downstream of FGF controls elongation of an amniote embryo (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-07-09
    Description: Vertebrate embryos are characterized by an elongated antero-posterior (AP) body axis, which forms by progressive cell deposition from a posterior growth zone in the embryo. Here, we used tissue ablation in the chicken embryo to demonstrate that the caudal presomitic mesoderm (PSM) has a key role in axis elongation. Using time-lapse microscopy, we analysed the movements of fluorescently labelled cells in the PSM during embryo elongation, which revealed a clear posterior-to-anterior gradient of cell motility and directionality in the PSM. We tracked the movement of the PSM extracellular matrix in parallel with the labelled cells and subtracted the extracellular matrix movement from the global motion of cells. After subtraction, cell motility remained graded but lacked directionality, indicating that the posterior cell movements associated with axis elongation in the PSM are not intrinsic but reflect tissue deformation. The gradient of cell motion along the PSM parallels the fibroblast growth factor (FGF)/mitogen-activated protein kinase (MAPK) gradient, which has been implicated in the control of cell motility in this tissue. Both FGF signalling gain- and loss-of-function experiments lead to disruption of the motility gradient and a slowing down of axis elongation. Furthermore, embryos treated with cell movement inhibitors (blebbistatin or RhoK inhibitor), but not cell cycle inhibitors, show a slower axis elongation rate. We propose that the gradient of random cell motility downstream of FGF signalling in the PSM controls posterior elongation in the amniote embryo. Our data indicate that tissue elongation is an emergent property that arises from the collective regulation of graded, random cell motion rather than by the regulation of directionality of individual cellular movements.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3118990/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3118990/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benazeraf, Bertrand -- Francois, Paul -- Baker, Ruth E -- Denans, Nicolas -- Little, Charles D -- Pourquie, Olivier -- R01 GM076692/GM/NIGMS NIH HHS/ -- R01 GM076692-06/GM/NIGMS NIH HHS/ -- R01 HD043158-01/HD/NICHD NIH HHS/ -- R02 HD043158/HD/NICHD NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Jul 8;466(7303):248-52. doi: 10.1038/nature09151.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Kansas City, Missouri 64110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20613841" target="_blank"〉PubMed〈/a〉

    Quantitative reactivity profiling predicts functional cysteines in proteomes (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-11-19
    Description: Cysteine is the most intrinsically nucleophilic amino acid in proteins, where its reactivity is tuned to perform diverse biochemical functions. The absence of a consensus sequence that defines functional cysteines in proteins has hindered their discovery and characterization. Here we describe a proteomics method to profile quantitatively the intrinsic reactivity of cysteine residues en masse directly in native biological systems. Hyper-reactivity was a rare feature among cysteines and it was found to specify a wide range of activities, including nucleophilic and reductive catalysis and sites of oxidative modification. Hyper-reactive cysteines were identified in several proteins of uncharacterized function, including a residue conserved across eukaryotic phylogeny that we show is required for yeast viability and is involved in iron-sulphur protein biogenesis. We also demonstrate that quantitative reactivity profiling can form the basis for screening and functional assignment of cysteines in computationally designed proteins, where it discriminated catalytically active from inactive cysteine hydrolase designs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3058684/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3058684/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weerapana, Eranthie -- Wang, Chu -- Simon, Gabriel M -- Richter, Florian -- Khare, Sagar -- Dillon, Myles B D -- Bachovchin, Daniel A -- Mowen, Kerri -- Baker, David -- Cravatt, Benjamin F -- CA087660/CA/NCI NIH HHS/ -- MH084512/MH/NIMH NIH HHS/ -- R01 CA087660/CA/NCI NIH HHS/ -- R01 CA087660-09/CA/NCI NIH HHS/ -- R01 GM085117/GM/NIGMS NIH HHS/ -- R01 GM090294/GM/NIGMS NIH HHS/ -- R01 GM090294-02/GM/NIGMS NIH HHS/ -- R37 CA087660/CA/NCI NIH HHS/ -- R37 CA087660-10/CA/NCI NIH HHS/ -- U54 MH084512/MH/NIMH NIH HHS/ -- U54 MH084512-030004/MH/NIMH NIH HHS/ -- England -- Nature. 2010 Dec 9;468(7325):790-5. doi: 10.1038/nature09472.

    Computational design of proteins targeting the conserved stem region of influenza hemagglutinin (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-05-14
    Description: We describe a general computational method for designing proteins that bind a surface patch of interest on a target macromolecule. Favorable interactions between disembodied amino acid residues and the target surface are identified and used to anchor de novo designed interfaces. The method was used to design proteins that bind a conserved surface patch on the stem of the influenza hemagglutinin (HA) from the 1918 H1N1 pandemic virus. After affinity maturation, two of the designed proteins, HB36 and HB80, bind H1 and H5 HAs with low nanomolar affinity. Further, HB80 inhibits the HA fusogenic conformational changes induced at low pH. The crystal structure of HB36 in complex with 1918/H1 HA revealed that the actual binding interface is nearly identical to that in the computational design model. Such designed binding proteins may be useful for both diagnostics and therapeutics.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3164876/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3164876/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fleishman, Sarel J -- Whitehead, Timothy A -- Ekiert, Damian C -- Dreyfus, Cyrille -- Corn, Jacob E -- Strauch, Eva-Maria -- Wilson, Ian A -- Baker, David -- AI057141/AI/NIAID NIH HHS/ -- AI058113/AI/NIAID NIH HHS/ -- GM080209/GM/NIGMS NIH HHS/ -- P01 AI058113/AI/NIAID NIH HHS/ -- P01 AI058113-07/AI/NIAID NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 May 13;332(6031):816-21. doi: 10.1126/science.1202617.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21566186" target="_blank"〉PubMed〈/a〉

    Computation-guided backbone grafting of a discontinuous motif onto a protein scaffold (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-10-25
    Description: The manipulation of protein backbone structure to control interaction and function is a challenge for protein engineering. We integrated computational design with experimental selection for grafting the backbone and side chains of a two-segment HIV gp120 epitope, targeted by the cross-neutralizing antibody b12, onto an unrelated scaffold protein. The final scaffolds bound b12 with high specificity and with affinity similar to that of gp120, and crystallographic analysis of a scaffold bound to b12 revealed high structural mimicry of the gp120-b12 complex structure. The method can be generalized to design other functional proteins through backbone grafting.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Azoitei, Mihai L -- Correia, Bruno E -- Ban, Yih-En Andrew -- Carrico, Chris -- Kalyuzhniy, Oleksandr -- Chen, Lei -- Schroeter, Alexandria -- Huang, Po-Ssu -- McLellan, Jason S -- Kwong, Peter D -- Baker, David -- Strong, Roland K -- Schief, William R -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Oct 21;334(6054):373-6. doi: 10.1126/science.1209368.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22021856" target="_blank"〉PubMed〈/a〉
