United KingdomResearchers at the University of Osaka have developed a novel method called the CLiB assay to track lipid molecules within living cells. The technique uses yeast cells, liposomes, and fluorescence readouts to screen thousands of protein variants, identifying those that bind specifically to lipids. This approach enables the creation of highly sensitive biosensors capable of detecting rare signaling lipids like PI(3,5)P2, which are challenging to observe due to their low abundance. Using this method, scientists discovered that under stress conditions, such as increased salt exposure, PI(3,5)P2 accumulates in specific membrane regions. Additionally, the probe revealed that PI(3,5)P2 is concentrated at sites involved in cellular self-cleanup processes. The CLiB assay has potential applications in studying diseases linked to membrane dysfunction, including cancer, diabetes, and neurodegenerative disorders.
