Phosphoinositides in Subcellular Targeting and Enzyme Activation

Cells of the immune system are activated by a variety of stimuli that are derived from other cells, ingested material or from invading microorganisms. This issue of CTMI focuses on the mechanisms of phosphoinositide-mediated protein recruitment to intracellular membranes.

From the reviews:

"The book consists of seven chapters that focus on the various functions of PtdIns. summarises recent advances in the burgeoning field of inositol lipids and provides a snapshot of where the field stands in 2003. The field is moving rapidly but this volume will be a useful addition for many researchers who have only recently discovered that their favourite protein is regulated by PtdIns." (Shamshad Cockcroft, nature cell biology, Vol. 6 (6), June, 2004)

The reversible recruitment of intracellular protein complexes to membranes is essential for immune cell functions, including chemotaxis, phagocytosis and signalling. Such recruitment is often controlled by phosphorylated derivatives of phosphatidylinositol, known as phosphoinositides. These lipids also serve to activate enzyme systems that carry out complex reactions such as chromatin remodelling and pre-mRNA procesing. This issue of Current Topics in Microbiology and Immunology presents an overview of how phosphoinositides function in protein recruitment and enzyme activation and presents physiologically important examples of protein-phosphoinositide interactions.
