Preview Small GTPases and Their Regulators Part D

Preface In 1955 we edited three volumes of Methods in Enzymology (255, 256, 257) dedicated to small GTPases. Since then this field has exploded, and these monomeric, regulatory proteins are now firmly established as a common focus of interest in a wide variety of research areas including cell and developmental biology, immunology, neurobiology, and, more re- cently, microbiology. After talking with colleagues, it became apparent that all three volumes needed to be significantly updated. We have, there- fore, attempted to identify the major new areas and themes that have emerged. This volume covers the Rho GTPase family. These proteins are key regulators of the actin cytoskeleton, and since the last volume on the subject there has been significant progress in identifying and characterizing the biochemical pathways associated with the three best characterized members of this family, Rho, Rac, and Cdc42. In the past five years, interest has also widened to a much broader community, as it has become clear that Rho GTPases also participate in the regulation of many other signaling path- ways, notably activation of the JNK and p38 MAP kinase pathways and of transcription factors such as SRF and NF-KB. This ability to coordinately regulate changes in the actin cytoskeleton with changes in gene transcription and other associated activities appears to be conserved from yeast to mammals. When the last volumes were published, the large diversity of both down- stream targets and upstream guanine nucleotide exchange factors that inter- act with Rho GTPases was not fully appreciated. Not surprisingly, therefore, these figure more prominantly this time around. Also, although it was thought likely that Rho GTPases might participate in many processes de- pendent on the organization of filamentous actin, it has now been directly shown that these proteins control cell movement, phagocytosis, growth cone guidance, and cytokinesis. An additional exciting new development has been the identification and characterization of numerous proteins en- coded by pathogenic bacteria that directly affect the activity of mammalian Rho GTPases. We very much hope that this and the accompanying volumes covering the Ras family (Volumes 332 and 333) and the small GTPases involved in membrane trafficking (Volume 329) will provide a useful source of practical information for anyone entering the field. None of this would have been XV xvi ECAFERP possible without the talents and commitment of all our colleagues who have contributed to these volumes. We are indebted to them. ALAN HALL WILLIAM E.

NEUDAUER and IAN G. MACARA Introduction TC10 is a member of the Rho family of small GTPases. We have previously characterized the biochemistry, cellular effects, and effector in- teractions of TC10.1 This study established TC10 as a distinct member of the Rho family most closely related to Cdc42. In NIH 3T3 cells, the ectopic expression of hemagglutinin (HA)-tagged, gain-of-function TC10 induces long filopodia and loss of stress fibers. TC10 interacts with a subset of those effector proteins that bind to Cdc42. TC10 also interacts with several distinct proteins that are specific for TC10. 2 This article describes the methods used for the mutagenesis ofT C10 and the set of vectors used for the purification of recombinant proteins and mammalian expression of TC10. It also de- scribes the biochemical characterization of TC10 and various methods used to study the interaction of TC10 with putative effector proteins. Mutagenesis and Subcloning of TC10 We have tested several methods for the introduction of point mutations and have found megaprimer polymerase chain reaction (PCR) to be a relatively consistent, cost effective, and reliable technique. 3 Briefly,a n inter- nal primer is designed that contains the nucleotide substitution(s). An initial round of PCR is performed with this primer and a primer to either the 5' or 3' end of the sequence. In general, we include a BamHI site in the 5' primer and an EcoRI site in the 3' primer to facilitate subcloning. Restric- tion enzymes usually cut the ends of PCR products inefficiently and are therefore digested with high concentrations of BamHI and EcoRI at 37 ° for greater than 4 hr. To facilitate the expression of TCI0 and other proteins in bacteria, yeast, and mammalian cells, we have designed a set of vectors with similar I C. L. Neudauer, G. Joberty, N. Tatsis, and I. G.

The majority of these vectors produce N-terminally tagged fusion proteins; C-terminal tagging of the small GTPases is usually avoided as most of these proteins undergo posttranslational modification (e.g., prenylation, carboxymethylation) at their C termini. Each vector contains a BamHI site in the same reading frame as pGEX-2T (Amersham Pharmacia, Piscataway, N J; Fig. 1). The pK series of vectors derives expression from a cytomegalovirus (CMV) promoter and contains splice donor and acceptor sites upstream of the initiation codon to increase the efficiency of mRNA export from the nucleus. The vectors contain a simian virus 40 (SV40) origin, so they will replicate in COS-7 cells (which contain the SV40 large T antigen). They are designed for high-level expression in transient transfections and do not contain a eukaryotic selectable marker. This set of vectors allows for the rapid characterization of TC10 or other proteins by prokaryotic expression and purification and by mammalian expression and immunoprecipitation, immunoblotting, or immunofluorescence. The purification methods are listed in Table I. The antibodies used and their concentrations for immu- noblots or immunofluorescence are listed in Table II.
