The regulation of PI 3-kinase second messenger molecules, PtdIns(3,4)P2 and PtdIns 3-P.

Funded Activity Summary

Cells respond to the external environment, hormones, and growth factors by generating messages inside the cell that send a signal to the nucleus that stimulates cell growth. One such signalling network is that produced by membrane lipids known as phosphoinositides. Enzymes that produce these signals are known as kinases. There has been considerable interest in the PI 3-kinase as the signals generated by this enzyme are increased in many human cancers. Inherited cancer syndromes have been described that have lost the ability to switch off PI 3-kinase signals. The current project aims to investigate a recently identified enzyme called the 4-phosphatase that has the ability to terminate PI 3-kinase signals. Recent studies have shown this enzyme regulates cell growth. In addition key experiments have shown the enzyme is important as it may regulate certain strains of bacterial infection. This research proposal aims to investigate how the enzyme works to regulate these growth promoting signals. This may help us develop novel therapeutic strategies to control cell growth.
