The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

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.

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.Read moreRead less
