Abstract

Creation of a ShcA-Grb2 interaction is a key component of mitogenic signalling, but the mechanisms involved in regulating signal output from the complex are unclear. We have shown that two phosphotyrosine sites in ShcA interact with Grb2 and each has distinctive in vivo functions. Here a biosensor assay will be used to establish the hypothesis that association between ShcA and Grb2 influences binding to downstream signalling molecules, and ascertain how feedback phosphorylation regulates these interactions. We have also reported that Gab1 is bound to MT associated Grb2, so to prove the premise that this plays a part in signalling, Gab1 expression will be disrupted by RNA interference, and the effects on MT induced mitogenesis determined.
