Abstract

In the last 10 years we have come to appreciate the central role that phosphatidylinositol (PI)-3,4,5-P(3)plays in regulating a vast array of biological responses to extracellular signals. The level of this phospholipid is low in resting cells but increases rapidly in response to growth factor/cytokine-stimulated plasma membrane recruitment and activation of PI-3-kinase. Within the last 3 years three enzymes, SHIP, SHIP2 and PTEN, that play key roles in regulating the level of PI-3,4,5-P(3)have been cloned. In this review I have attempted to summarize our current knowledge regarding these three intriguing phosphatases.
