Why are membrane lipids asymmetrical?
Why are membrane lipids asymmetrical? The human red blood cell is functionally specialized for transporting oxygen. In order to maximize oxygen capacity, it has no nucleus or organelles, consisting primarily of plasma membrane and [...]
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 [...]
How is clathrin recruited to the plasma membrane?
How is clathrin recruited to the plasma membrane? Clathrin-mediated endocytosis is triggered by phosphatidylinositol-4,5-bisphosphate (PIP2) accumulation within the plasma membrane. PIP2 accumulates as a result of phosphoinositide catalysis by the lipid kinases, phosphatidylinositol-4-kinase (PI4K) [...]
What is clathrin-mediated endocytosis?
What is clathrin-mediated endocytosis? Clathrin-mediated endocytosis (CME) is a vesicular transport event that facilitates the internalization and recycling of receptors engaged in a variety of processes, including signal transduction (G-protein and tyrosine kinase receptors), [...]
What is caveolar endocytosis?
What is caveolar endocytosis? Caveolar endocytosis is a clathrin-independent endocytic process which involves bulb-shaped, 50-60nm plasma membrane invaginations called caveolae (or ‘little caves’). Caveolae formation is driven by integral membrane proteins called caveolins as [...]

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.
