Christopher Schirwitz's thesis focuses on improving the quality of in situ synthesized high-complexity peptide micro arrays. Micro arrays containing proteins or small protein fragments in the form of peptides have become of great interest in proteomic research. With the help of these microarrays a large number of potential target molecules can be screened for interaction with a probe in a short timeframe. However, protein and peptide micro arrays are still lagging behind oligonucleotide arrays in terms of density, quality and manufacturing costs. A new approach developed at the German Cancer Research Center (DKFZ) has improved the synthesis of high-density peptide arrays. The current technology is capable of producing arrays with up to 40,000 different peptides per square cm by means of micro particle-based solid phase peptide synthesis. However, in situ synthesis approaches bear a conceptual disadvantage: The quality of the peptides is dependent on the efficiency of the synthesis so that peptide fragments are present in the resulting array among the desired full-length peptides. In peptide-protein interaction studies such peptide fragments. The central achievement of this thesis is the development of a new method allowing for the fast one-step purification of entire arrays without loss of resolution or spatial information. Christopher Schirwitz's work has resulted in a number of publications in high ranking journals.

This volume is designed to provide an understanding of current and potential therapies for osteoporosis. The opening chapter introduces the cells of bone and their interactions. Several following chapters describe factors affecting bone including systemic hormones with significant effects on bone, and local mediators including growth factors, prostaglandins, cytokines and chemokines. Topics that have commanded particular attention recently are calcium, FGF-23, nervous system bone interactions. Drugs that cause bone loss provide important information on mechanism as well as therapeutic considerations. An overview of the genetics of bone disorders and a discussion of the pathophysiology of osteoporosis establish the clinical context. The final chapters discuss current and potential osteoporosis treatments.

Proteins act as macromolecular machinery that mediate many diverse biological processes - the molecular mechanisms of this machinery has fascinated biologists for decades. Analysis of the kinetic and thermodynamic features of these mechanisms could reveal unprecedented aspects of how the machinery function and will eventually lead to a novel understanding of various biological processes. This dissertation comprehensively demonstrates how two universally conserved guanosine triphosphatases in the signal recognition particle and its membrane receptor maintain the efficiency and fidelity of the co-translational protein targeting process essential to all cells. A series of quantitative experiments reveal that the highly ordered and coordinated conformational states of the machinery are the key to their regulatory function. This dissertation also offers a mechanistic view of another fascinating system in which multistate protein machinery closely control critical biological processes.

Actin is an extremely abundant protein that comprises a dynamic polymeric network present in all eukaryotic cells, known as the actin cytoskeleton. The structure and function of the actin cytoskeleton, which is modulated by a plethora of actin-binding proteins, performs a diverse range of cellular roles. Well-documented functions for actin include: providing the molecular tracks for cytoplasmic streaming and organelle movements; formation of tethers that guide the cell plate to the division site during cytokinesis; creation of honeycomb-like arrays that enmesh and immobilize plastids in unique subcellular patterns; supporting the vesicle traffic and cytoplasmic organization essential for the directional secretory mechanism that underpins tip growth of certain cells; and coordinating the elaborate cytoplasmic responses to extra- and intracellular signals. The previous two decades have witnessed an immense accumulation of data relating to the cellular, biochemical, and molecular aspects of all these fundamental cellular processes. This prompted the editors to put together a diverse collection of topics, contributed by established international experts, related to the plant actin cytoskeleton. Because the actin cytoskeleton impinges on a multitude of processes critical for plant growth and development, as well as for responses to the environment, the book will be invaluable to any researcher, from the advanced undergraduate to the senior investigator, who is interested in these areas of plant cell biology.

RAN: AN ATYPICAL GTPASE Mark G. Rush and Peter D'Eustachio New York University School o/Medicine. Department,o/Biochemistry New York NY 10016 ABSTRACT GTPases, proteins that bind and hydrolyze GTP (guanosine triphos- phate) are critical regulators of many metabolic pathways. Although these proteins are enzymes that catalyze the hydrolysis of GTP to GDP + Pi, their primary function is not the hydrolysis of GTP per se, but rather the coupling of this hydrolysis to metabolic regulation. Such coupling is gen- erally achieved through the interaction of the GTP-bound form of the GTPase with proteins known as *effectors. Effectors are often enzymes whose activities are modulated by the GTPase. However, effectors can also be structural proteins involved in assembling intracellular macromo- lecular complexes, such as actin filaments and microtubules, as well as proteins involved in the intracellular transport of proteins and RNAs. In- deed, the subject of this anthology, the small GTPase Ran, may exert most or all of its regulatory functions by interacting with non-enzyme effectors. This property of Ran distinguishes it from other well studied GTPases, and has resulted in the elucidation of novel mechanisms of Ran action that are quite distinct from previously established paradigms of GTPase function. 1. INTRODUCTION The Ras-related nuclear protein Ran is a highly conserved (80% identity among yeasts and humans) member of the Ras superfamily of small GTP binding and hydrolyzing proteins.
