Microtubule capture by E-cadherin: a novel mechanism for dynamic cell-cell adhesion.

Funded Activity Summary

This project studies the molecular mechanisms responsible for holding cells together in normal tissues. Such cell-to-cell adhesion is mediated by the cadherin family of molecules, which reside at the surfaces of cells. Cadherins allow cells to recognize one another and, upon recognition, adhere to one another. By this means populations of individual cells can be linked together into cohesive populations (i.e. the tissues or organs of the body). The importance of cadherin adhesion is exemplified by the well-documented observation that disruption of cadherin adhesion contributes to many important diseases, including inflammation of epithelia and cancers. Thus understanding the mechanisms by which cadherins hold cells together is necessary for us to understand the molecular basis of commondisease. It has long been known that cadherins work in cooperation with elements within the cell, called the cytoskeleton. My lab has recently made the novel discovery that microtubules, specific components of the cytoskeleton, can regulate the functionof cadherin adhesion molecules. Inparticular, microtubules appear to affect how cadherins can participate in dynamic cell processes necessary for cells to be properly organized in tissues. In this project we will probe the molecular mechanisms responsible for this effect of microtubules. The information obtained will provide important new insights into how dynamic cadherin adhesion is controlled, to help our understanding of the cellular mechanisms that couple cells into tissues, and how they may be disrupted in diesase.
