Mary Beckerle (University of Utah) Part 2: Discovery and Characterization

http://www.ibiology.org/ibioseminars/cell-biology/mary-beckerle-part-2.html In the second segment, I describe the identification of the focal adhesion protein, zyxin, by my lab. Recent work revealed that zyxin is down-regulated upon expression of the Ewing sarcoma oncoprotein, EWS-FLI. Loss of zyxin expression results in enhanced cell motility and is also associated with failed apoptotic signaling. Evidence that zyxin shuttles between focal adhesions and the nucleus is presented. The impact of reduced zyxin expression on tumor progression is discussed. See more at http://www.ibiology.org
