    Notes: [Auszug] A shocking thing has happened in the world of the cytoskeleton, the complex of proteins responsible for cell shape and movement. One of the most important structures it forms is the spindle, which ensures the faithful delivery of replicated chromosomes to daughter cells following cell division. ...

    F-actin Distribution of Dictyostelium Myosin I Double Mutants (1994)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 41 (1994), S. 0

    Topics: Biology
    Notes: The roles of the myosin I class of mechanoenzymes have been investigated by single and double gene knockout studies in the amoeba Dictyostelium discoideum. Cells lacking different myosin I pairs (myoA-/myoB-, myoB-/myoC-, and myoA-/myoC-) were examined with respect to their cytoskeletal organization. F-actin localization by rhodamine-phalloidin staining of cells indicates that the myoA-/myoB-, myoB-/myoC-, and myoA-/myoC- cells appear to redistribute their F-actin more slowly than wild type cells upon adhesion to a substrate. These studies suggest that Dictyostelium myoA, myoB, and myoC may have overlapping roles in maintaining the integrity or organization of the cortical membrane cytoskeleton.

    The Role of Unconventional Myosins in Dictyostelium Endocytosis (2000)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 47 (2000), S. 0 
    Details
    ISSN: 1550-7408

    Notes: Dictyostelium discoideum is a simple eukaryote amenable to detailed molecular studies of the endocytic processes phagocytosis and macropinocytosis. Both the actin cytoskeleton and associated myosin motors are well-described and a range of mutants arc now available that enable characterization of the role of the cytoskeleton in a range of cellular functions. Molecular genetic studies have uncovered roles for two different classes of Dictyostelium unconventional myosins in endocytosis. The class I myosins contribute to both macropinocytosis and phagocytosis by playing a general role in controlling actin-dependent manipulations of the actin-rich cortex. A class VII myosin has been shown to be important for phagocytosis. This brief review summarizes what is known about the role of these different myosins in both fluid and particle uptake in this system.

    Notes: [Auszug] Motor proteins use chemical energy, for example from ATP, to generate unidirectional movement along a filamentous track. How a group of proteins acquired and then varied this property to generate a range of movements as evolution proceeded is a fascinating problem in biology. Answers are within ...
