   Abstract : The family of phosphorylated inositol compounds consists of soluble cytosolic inositol phosphates and insoluble inositol phospholipids, localized in cellular membranes and the nuclear matrix. Although inositol phospholipids only account for 5-10% of total plasma membrane lipids, these compounds and their inositol phosphate derivatives play an important role in a broad range of cellular processes including intracellular Ca 2+ signalling, ion channel regulation, vesicle trafficking, both exo- and endocytosis, cell growth and apoptosis.
