Abstract

A potential SH2-binding motif recognised by the SH2 domain of phosphoinositide- 3-kinase (PI-3 kinase) is conserved in several neuronal nicotinic receptor (nAChR) subunits. Its significance will be explored using mutagenesis and expression in stable cell lines, facilitating biochemical approaches. Given the role of PI-3 kinase in regulation of the endocytic pathway, the trafficking and upregulation of wildtype and mutated nAChR will be compared using confocal microscopy. This study will establish if nAChR are linked to lipid signalling pathways. If so, this proof of concept project will provide the first evidence for such an association between a ligand gated ion channel and PI-3 kinase.
