Analysis of transiently overexpressed Src Y527F on phosphoproteome signalling<br />

Protein phosphorylation <strong>and</strong> dephosphorylation is a major <strong>signaling</strong> method for activating <strong>and</strong><br />

inactivating cell proteins. Here we describe the overexpression of constitutively activated Src<br />

Y527F <strong>and</strong> a novel method to identify target proteins down-stream of Src. Src plays important<br />

roles in cell differentiation, proliferation, <strong>and</strong> survival. For example, stimulation of the<br />

epidermal growth factor receptor, which leads to cell proliferation, results in Src activation.<br />

Src is activated during the G2/M transition. Src plays a role in cell adhesion, cell morphology<br />

<strong>and</strong> motility, <strong>and</strong> bone resorption.<br />
