We have previously shown that treatment of T lymphocytes with mitogenlc llgands induces a rapid activation of omithlne decarboxylase (ODC) through a mechanism that is independent of protein synthesis but requires energy and an intact cytoskeleton. Here we show by immunoprecipitation experiments and by chemical analyses that ODC is covalently linked to the cell membrane by inositol. Treatment of sonicated cells with a phosphatidylinositol-specific phospholipase C from B. thurlngiensis caused a rapid Mold increase in ODC activity. Similar treatment of intact ceils had no effect, suggesting that the ODC is attached to the cytoplasmic surface of the membrane. We conclude that ODC release and activation occur by a novel mechanism involving phosphatidyllnositol breakdown following ligand-receptor interaction.
