摘要：
Recently there has been a flurry of interest in the regulation of the homo-dimeric calcium-activated chloride channel ANO1 (also known as TMEM16A) by phosphatidylinositol (4,5)-bisphosphate (PI(4,5)P-2). These recent studies show that upon Ca2+ binding, PI(4,5)P-2 cooperates to maintain the conductive state of ANO1. PI(4,5)P-2 does so by binding to sites or modules on the protein's cytosolic side. These findings add a new function to the PI (4,5)P-2 repertoire and a new dimension to ANO1 gating.
