A novel acidic form of the phosphatidylinositol transfer protein is preferentially retained in permeabilized Swiss mouse 3T3 fibroblasts.

Abstract

By use of indirect immunofluorescence it was shown that phophatidylinositol transfer protein (PI-TP) remains associated with the Golgi system of Swiss mouse 3T3 fibroblasts after permeabilization with streptolysin O. By Western blot analysis it was demonstrated that intact cells contain the phosphatidylinositol-bound form of PI-TP (pI 5.5) and a novel more… (More)
