Abstract

The fundamental role of 3-phosphorylated inositol lipids, particularly phosphatidylinositol 3,4,5-trisphospate (PIP3), in the activation of intracellular signalling pathways is becoming increasingly evident. Recently we, and others, have identified ADP-ribosylation factor (ARF) guanine nucleotide exchange factors and ARF GTPase-activating proteins as potential in vivo PIP3 receptors; data that highlights a potential role for PIP3 in the regulation of ARF signalling. Since ARF signalling is linked to a critical role in eukaryotic vesicle trafficking we hereby propose a model implicating PIP3 in the regulation of ARF induce vesicle fusion at the plasma membrane. Experiments described within this proposal are aimed at proving this model.
