    Notes: Abstract This review surveys the kinds of protein complex that participate in cell communication and identifies, where possible, general principles by which they form and act. It also advances the notion that biophysical constraints imposed by macromolecular crowding and diffusion have had a controlling influence on the evolution of cell signaling pathways. Complexes associated with the bacterial aspartate receptor, with eucaryotic tyrosine kinase receptors, with T-cell receptors, and with focal contacts are examined together with proteins that serve as adaptors, anchors, and scaffolds for signaling complexes. The importance of diffusion in controlling the numbers and locations of signaling complexes is discussed, as is the special role played by membranes in signaling pathways.

    Notes: The phenomenon of allostery is conventionally described for small symmetrical oligomeric proteins such as hemoglobin. Here we review experimental evidence from a variety of systems-including bacterial chemotaxis receptors, muscle ryanodine receptors, and actin filaments-showing that conformational changes can also propagate through extended lattices of protein molecules. We explore the statistical mechanics of idealized linear and two-dimensional arrays of allosteric proteins and show that, as in the analogous Ising models, arrays of closely packed units can show large-scale integrated behavior. We also discuss proteins that undergo conformational changes driven by the hydrolysis of ATP and give examples in which these changes propagate through linear chains of molecules. We suggest that conformational spread could provide the basis of a solid-state "circuitry" in a living cell, able to integrate biochemical and biophysical events over hundreds of protein molecules.

    Notes: [Auszug] CERTAIN chemicals have come to stand for particular areas of biological research. Think of fluorescein isothiocyanate; 2-deoxyglucose; bis-acrylamide; a-bung-arotoxin, anti-mouse immunoglobulin. Substances such as these are hitched so firmly to a line of research that you could almost use their ...

    Notes: [Auszug] THE conventional wisdom that micro-tubules run the entire length of nerve axons and dendrites probably comes from a paper by Weiss and Mayr (Acta Neuropath, supp V, 198; 1971). On page 200 these authors conclude that "each tubule is a single unitary entity, extending in uninterrupted and undivided ...

    Notes: [Auszug] IN recent years this subject has acquired the flavour of renaissance cosmology. There is the same abundance of speculative models and the same readiness to argue endlessly cyclicallyabout a limited number of facts. There is, in addition, something of the early astronomers in the personality of the ...

    Notes: [Auszug] LIKE the electron, the cell shows a different face according to how it is treated; at least, that is the conclusion to be drawn from recent papers on cell movement. Even the intuitive picture of the inside of the cell seems to depend on the techniques used. To the biochemist for example, who ...

    Notes: [Auszug] Many proteins in living cells appear to have as their primary function the transfer and processing of information, rather than the chemical transformation of metabolic intermediates or the building of cellular structures. Such proteins are functionally linked through allosteric or other ...

    Notes: [Auszug] ... This is an engaging, eclectic and strangely disturbing book. At one level it offers a pop-science account of biological patterns — wide-ranging, easy to read and very accessible, even for non-specialists. But beneath this, a subtext repeats insistently, page after page, like the beating ...

    Notes: [Auszug] ...Let's start on safe ground. We all agree, surely, that theory — the formulation of hypotheses — is important in biology. Techniques are essential, as is the careful collection of quantitative data. But without ideas to give them shape and meaning, those endless successions of base ...
