What steps are involved in the myosin powerstroke?
What steps are involved in the myosin powerstroke? Each myosin motor protein possesses ATPase activity and functions in a cyclical manner that couples ATP binding and hydrolysis to a conformational change in the protein. [...]
What are cytoskeletal cages?
What are cytoskeletal cages? Cytoskeletal components can assemble into cage-like structures within the cell. These cages serve to segregate intracellular regions or organelles, and can protect their contents from mechanical stress. At the level [...]
What is the plasma membrane?
What is the plasma membrane? Plasma membranes are subcellular structures, approximately 10nm thick, that form a protective boundary around the cell as well as the cell’s organelles. They serve to both impede foreign material [...]
How do mechanically-gated ion channels facilitate mechanotransduction?
How do mechanically-gated ion channels facilitate mechanotransduction? Mechanotransduction relies on the ability of cells to convert mechanical cues, such as stretch or compression, to biochemical signals. One way this occurs is through the activity [...]
How do lipid bilayer components move?
How do lipid bilayer components move? One of the tenets of the Fluid-Mosaic membrane model is that the components of the bilayers are free to move. Before describing the differences between lipid and protein [...]

Research Interests
The morphology of cells, organs and whole organisms is determined by the generation of forces on the immediate environment, which is either extracellular matrix or adjacent cells. We are currently engaged in studies to understand the detailed molecular mechanisms involved in a variety of phenomena from cancer metastasis to brain function. Further, we are developing several new tools and protocols for measuring cell forces at the molecular level, which are revealing many new aspects of how cells can both generate and respond to external forces. We have an effort underway to define quantitatively the steps involved in cell adhesion to and spreading on a matrix-coated surface. Using a variety of cell lines that are missing proteins in various motility pathways, we are determining the quantitative changes in the spreading process. This will enable us to generate a detailed model of the process of spreading that will be a model for further studies of how cells differentiate, regenerate tissues or metastasize.
Biography
Hailing from Columbia University, Prof Michael Sheetz has more than 40 years’ experience in the biomedical field. Introduced to Singapore by Prof Hew Choy Leong of the National University of Singapore’s Department of Biological Sciences, Prof Sheetz was sought to lead an RCE project. This resulted in a two-year effort to organise and submit a proposal on Mechanobiology where Prof Sheetz set the theme and direction of the Mechanobiology Institute (MBI). As Founding Director of the MBI, he led the institute for 10 years and built it into a world-leading research centre in the field of mechanobiology.
