We primarily use biophysical techniques to dissect these cascades at atomic and molecular resolution in order to understand and manipulate cellular processes. Among other work, we are currently using these studies to guide rational drug design and develop high throughput screens to identify modulators of key signaling components and to produce biosensors to monitor these cascades in real-time in cells.<\/p>\n<h3><span class=\"blue\">SELECTED PUBLICATIONS<\/span><span class=\"normalSizeFont\" style=\"color: #666666;line-height: 1.43em;margin: 0px;padding: 0px;background-color: #ffffff\"><span class=\"discreet\" style=\"margin: 0px;padding: 0px\">\u00a0<\/span><\/span><\/h3>\n<p><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=sondek%20j[Author]\"><span class=\"discreet\" style=\"margin: 0px;padding: 0px;background-color: #ffffff\"><span style=\"color: #666666\">Link to all <\/span>Pubs<\/span><\/a><\/p>\n<p>&nbsp;<\/p>\n<p>Dynamics of allosteric regulation of the phospholipase C-\u03b3 isozymes upon recruitment to membranes.<br \/>\nSiraliev-Perez E, Stariha JTB, Hoffmann RM, Temple BRS, Zhang Q, Hajicek N, Jenkins ML, Burke JE, Sondek J.
