Abstract
Mouse NIH3T3 fibroblast cells overexpressing phosphatidylinositol transfer protein ß (PI-TPß, SPIß cells) demonstrate a low rate of proliferation and a high sensitivity towards UV-induced apoptosis when compared with wtNIH3T3 cells. In contrast, SPIßS262A cells overexpressing a mutant PI-TPß that lacks the protein kinase C-dependent phosphorylation site Ser-262, demonstrate a phenotype
