TY - JOUR. T1 - Genetically encoded photoswitching of actin assembly through the Cdc42-WASP-Arp2/3 complex pathway. AU - Leung, Daisy W.. AU - Otomo, Chinatsu. AU - Chory, Joanne. AU - Rosen, Michael K.. PY - 2008/9/2. Y1 - 2008/9/2. N2 - General methods to engineer genetically encoded, reversible, light-mediated control over protein function would be useful in many areas of biomedical research and technology. We describe a system that yields such photo-control over actin assembly. We fused the Rho family GTPase Cdc42 in its GDP-bound form to the photosensory domain of phytochrome B (PhyB) and fused the Cdc42 effector, the Wiskott-Aldrich Syndrome Protein (WASP), to the light-dependent PhyB-binding domain of phytochrome interacting factor 3 (Pif3). Upon red light illumination, the fusion proteins bind each other, activating WASP, and consequently stimulating actin assembly by the WASP target, the Arp2/3 complex. Binding and WASP activation are reversed by far-red illumination. Our approach, in ...

Many signaling pathways control cell shape, and these pathways ultimately do so, at least in part, by regulating polymerization of actin. Members of the WASP (Wiskott-Aldrich syndrome protein) family appear to integrate such signals and are thus subject to a complex array of regulatory mechanisms. Activation of WASP through the Rho family GTPase Cdc42 and interaction with phosphatidylinositol 4,5-bisphosphate (PIP2) stimulate the Arp2/3 complex, which in turn promotes nucleation of actin filaments. Papers by Higgs and Pollard and Rohatgi et al. characterizing native WASP from bovine thymus and in vitro-translated N-WASP (where N refers to neuronal, even though this family member is widely expressed) and the Commentary by Zigmond provide new details of this multifaceted regulation. The NH2-terminus of WASP appears to interact with the COOH-terminus and block binding to Arp2/3. Activation by Cdc42 and PIP2 reduces the autoinhibitory binding and exposes the Arp2/3 binding region. Rohatgi et al. use ...

The member of Rho family of small GTPases Cdc42 plays important and conserved roles in cell polarity and motility. The Cdc42ep family proteins have been identified to bind to Cdc42, yet how they interact with Cdc42 to regulate cell migration remains to be elucidated. In this study, we focus on Cdc42ep1, which is expressed predominantly in the highly migratory neural crest cells in frog embryos. Through morpholino-mediated knockdown, we show that Cdc42ep1 is required for the migration of cranial neural crest cells. Loss of Cdc42ep1 leads to rounder cell shapes and the formation of membrane blebs, consistent with the observed disruption in actin organization and focal adhesion alignment. As a result, Cdc42ep1 is critical for neural crest cells to apply traction forces at the correct place to migrate efficiently. We further show that Cdc42ep1 is localized to two areas in neural crest cells: in membrane protrusions together with Cdc42 and in perinuclear patches where Cdc42 is absent. Cdc42 directly ...

Prerequisites for all modes of cell migration are cell-substratum interactions that require a sophisticated interplay of membrane dynamics and cytoskeletal rearrangement. Generally, a migrating cell is polarized with a distinct rear and front, from which it extends a wide and thin membrane protrusion- lamellipodium, small fingerlike projections- filopodia, and membrane blisters- blebs. The development of these structures is primarily driven by cytoskeletal contractions and actin polymerization, which are under regulation of several actin-binding proteins and the small GTPases Cdc42, Rac and Rho. Lamellipodia and filopodia are assumed to arise from polymerizing actin, pushing the membrane forward through a Brownian-ratchet mechanism. However, other models based on shifts in the local hydrostatic pressure have also been suggested since blebs are initially void of actin. Recently, fluxes of water through membrane-anchored water channels, aquaporins (AQPs), have been implicated in cell motility, ...

The constant self renewal and differentiation of adult intestinal stem cells maintains a functional intestinal mucosa for a lifetime. However, the molecular mechanisms that regulate intestinal stem cell division and epithelial homeostasis are largely undefined. We report here that the small GTPases Cdc42 and Rab8a are critical regulators of these processes in mice. Conditional ablation of Cdc42 in the mouse intestinal epithelium resulted in the formation of large intracellular vacuolar structures containing microvilli (microvillus inclusion bodies) in epithelial enterocytes, a phenotype reminiscent of human microvillus inclusion disease (MVID), a devastating congenital intestinal disorder that results in severe nutrient deprivation. Further analysis revealed that Cdc42-deficient stem cells had cell division defects, reduced capacity for clonal expansion and differentiation into Paneth cells, and increased apoptosis. Cdc42 deficiency impaired Rab8a activation and its association with multiple ...

This gene encodes a member of the DBL family of guanine nucleotide exchange factors. The encoded protein has been proposed to regulate the actin cytoskeleton by specifically activating the Rho-family GTPase Cdc42.

Rho GTPases comprise a family of molecular switches that control signal transduction pathways in eukaryotic cells. A conformational change induced upon binding GTP promotes an interaction with target (effector) proteins to generate a cellular response. A highly conserved function of Rho GTPases from yeast to humans is to control the actin cytoskeleton, although, in addition, they promote a wide range of other cellular activities. Changes in the actin cytoskeleton drive many dynamic aspects of cell behaviour, including morphogenesis, migration, phagocytosis and cytokinesis, and the dysregulation of Rho GTPases is associated with numerous human diseases and disorders. ...

DOCK-C subfamily proteins (DOCK6-8) partially conserve the Cdc42-interacting residues of DOCK939 and the Rac1-interacting residues of DOCK2.40 To understand the mechanism underlying the Cdc42 specificity of DOCK8, we performed X-crystallographic analysis of the complex between the DOCK8 DHR-2 domain and the dominant-negative T17N mutant of Cdc42 (supplemental Table 1). Two lobes (lobes B and C) of DOCK8 DHR-2 generate a cooperative interface with Cdc42 (Figure 6C) in a manner similar to DOCK9 DHR-2.39 Based on the DOCK6 structural model, it was predicted that Met1932 of DOCK6 would be incompatible with the aromatic side chain at position 56 (Phe, Tyr, or Trp) that is conserved in nearly all of the Rho family of GTPases.40 However, the DOCK8 DHR-2·Cdc42 complex structure revealed that DOCK8 Met1976, corresponding to Met1932 of DOCK6, assumes a bent side-chain conformation and thereby avoids the putative steric hindrance with the Phe56 side chain of Cdc42 (Figure 6D). When the structure of Rac1 ...

Members of the Rho family of GTP‐binding proteins function as molecular switches in biological response pathways that result in changes in the actin cytoskeletal architecture, the stimulation of cell cycle progression and gene transcription, and the regulation of intracellular trafficking activities (Van Aelst and DSouza‐Schorey, 1997; Hall, 1998; Bar‐Sagi and Hall, 2000; Erickson and Cerione, 2001). Three classes of proteins, GTPase‐activating proteins (GAPs), guanine nucleotide dissociation inhibitors (GDIs), and guanine nucleotide exchange factors (GEFs), regulate the cycling of these GTP‐binding proteins between their GDP‐bound and GTP‐bound states (Boguski and McCormick, 1993). Rho family proteins, such as Cdc42 and Rac, are activated by a number of upstream stimuli, as mediated by members of the Dbl (diffuse B‐cell lymphoma) family of GEFs (Whitehead et al, 1997; Hoffman and Cerione, 2002). One subgroup of the Dbl family, the Cool/Pix proteins (Cool for cloned‐out of ...

Cdc42 regulates key processes that are critical for mammary gland morphogenesis and become disrupted during the development, progression, and metastasis of breast cancer. However, the contribution of Cdc42 to normal and neoplastic mammary gland development in vivo remains poorly understood. We were therefore interested in investigating the effects of Cdc42 overexpression on mammary gland morphogenesis as a first step toward understanding how its overexpression may contribute to mammary tumorigenesis.Methods: We developed a tetracycline-regulatable Cdc42 ...

In yeast, Cdc42 is required to polarize the site of bud formation, and several in vitro studies show that it may also be required for efficient polarization of eukaryotic cells (Etienne-Manneville, 2004). Furthermore, for monocytes in culture, blocking Cdc42 signaling leads to a failure to receive and respond to chemotactic cues (Allen et al., 1998; Chou et al., 2003; Srinivasan et al., 2003). However, our in vivo studies in the fly embryo reveal no significant effect on the numbers of hemocytes recruited to laser wounds after 1 h in Cdc42 mutant embryos. This finding is true also for embryos expressing the dominant-negative Cdc42N17 and Cdc42S89 transgenes specifically in hemocytes (Fig. 3 a). Both developmental dispersal of hemocytes and their recruitment to sites of tissue damage appears grossly normal. But on closer inspection, we observe that hemocyte motility is abnormal. During the migratory phase, and once hemocytes have reached the wound, we frequently see cells with several leading ...

Catalytic domain of the Protein Serine/Threonine Kinase, DMPK-related cell division control protein 42 binding kinase alpha. Serine/Threonine Kinases (STKs), DMPK-like subfamily, DMPK-related cell division control protein 42 (Cdc42) binding kinase (MRCK) alpha isoform, catalytic (c) domain. STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The DMPK-like subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase. MRCK is activated via interaction with the small GTPase Cdc42. MRCK/Cdc42 signaling mediates myosin-dependent cell motility. MRCKalpha is expressed ubiquitously in many tissues. It plays a role in the regulation of peripheral actin reorganization and neurite outgrowth. It may also play a role in the transferrin iron uptake pathway. ...

Objectives: The Rho subfamily of small GTPases, including RhoA, Rac1, and Cdc42, regulates diverse cellular functions, including polarity and migration. Our prior studies established an essential role for Cdc42 in vascular network assembly, demonstrating that the genetic inactivation of Cdc42 yields defective vascular morphogenesis due to impaired migration of endothelial precursor cells. We have further shown that protein kinase Ciota and glycogen synthase kinase-3 Beta are downstream effectors of Cdc42 involved in mediating vascular network assembly. The objective of this study was to elucidate the guanine nucleotide exchange factors (GEFs) that activate Cdc42; specifically, we investigated the role of Zizimin1 and its effects on Cdc42 and vasculogenesis.. Methods: We performed affinity pulldown assays using a nucleotide-free Cdc42 G15A mutant that specifically binds to Cdc42 GEFs. Mass spectrometric analysis identified Zizimin1 as a candidate Cdc42 GEF.. Results: During vasculogenesis in ...

Several studies have identified Rho family GTPases (i.e. Rho, Rac, Cdc42) as mediators of diverse critical cellular processes, such as actin cytoskeleton remodeling, gene transcription, cell-cell adhesion, and cell cycle progression. However, more recent data highlight an essential role for Rho GTPases as regulators of neuronal morphology and neuronal survival. In particular, Rac GTPase generally induces neurite outgrowth and promotes neuronal survival while Rho GTPase typically provokes neurite retraction and induces neuronal apoptosis. However, the precise signaling pathways that regulate neuronal survival downstream of Rho GTPases and the potential involvement of dysregulated activity of Rho GTPases as a causative factor in the progression of neurodegenerative diseases remains to be elucidated. Consistent with a pro-survival function for Rac in neurons, inhibition of Rac with Clostridium difficle toxin B (ToxB) or expression of a dominant negative Rac1 mutant significantly induces activation of the

The sequential and regulated recruitment of leukocytes into tissues by chemoattractants is essential for effective clearance of pathogens and healing. The Rho GTPases Cdc42, Rac, and Rho are important for establishing and maintaining migratory polarity. Most chemoattractants for phagocytes signal either through seven transmembrane G-protein-coupled receptors (GPCRs) or tyrosine kinase receptors. Y721 is the most important for chemotaxis because it recruits phospholipase-C-γ (PL C-γ) and the p85 subunit of class 1A PI3Ks, both of which are implicated in the initiation of chemotaxis. Several intracellular signaling complexes contribute to the polarization of phagocytes in response to chemoattractants, and they probably act together to allow optimal chemotaxis. Cdc42 is implicated in multiple types of cell polarity, including axon specification, yeast mating, and epithelial polarity. There are several PLC isoforms, of which PLCβ2 and PLCβ3 are activated by GPCR signaling in neutrophils, whereas PLCβ

PAK proteins are involved in the regulation of cellular processes such as gene transcription, cell morphology, motility and apoptosis (Bagrodia and Cerione, 1999; Daniels and Bokoch, 1999; Jaffer and Chernoff, 2002). Our results illustrate that different PAK proteins fulfil distinct functions in the same cell. In the developing photoreceptor cells, D-PAK is required in growth cones to control axon guidance (Hing et al., 1999) whereas Mbt is localised at AJs and is required for cell morphogenesis.. One major difference between group I and group II PAKs is the regulation of kinase activity. For group I PAK proteins it has been shown that binding of GTP-bound Cdc42 or Rac releases the inhibitory effect of the KID on catalytic activity (Buchwald et al., 2001; Chong et al., 2001; Lei et al., 2000). The lack of an obvious KID in group II PAKs (Fig. 5C) is reflected by their distinct biochemical properties. In contrast to group I PAKs, a slightly reduced rather than enhanced kinase activity is observed ...

The Rho family of GTPases is a family of small (~21 kDa) signaling G proteins, and is a subfamily of the Ras superfamily. The members of the Rho GTPase family have been shown to regulate many aspects of intracellular actin dynamics, and are found in all eukaryotic kingdoms, including yeasts and some plants. Three members of the family have been studied in detail: Cdc42, Rac1, and RhoA. All G proteins are molecular switches, and Rho proteins play a role in organelle development, cytoskeletal dynamics, cell movement, and other common cellular functions. Identification of the Rho family of GTPases began in the mid-1980s. The first identified Rho member was RhoA, isolated serendipitously in 1985 from a low stringency cDNA screening. Rac1 and Rac2 were identified next, in 1989 followed by Cdc42 in 1990. Eight additional mammalian Rho members were identified from biological screenings until the late 1990s, a turning point in biology where availability of complete genome sequences allowed full ...

Rho GTPases are master regulators of many immunoreceptors, ranging from receptors required for differentiation and maturation of immune cells and for pathogen recognition to receptors involved in pathogen uptake and the subsequent host signaling responses. Several TLRs induce the activation of the Rho family GTPases Rac, Rho, and Cdc42. Almost every cell type, including professional innate immune cells such as macrophages, neutrophils, and dendritic cells, responds to TLR stimulation by activating Rho GTPases rapidly (8, 20, 31). Similarly, lung epithelial cells induce Rho GTPase activation when they encounter TLR ligands. It seems apparent that RhoA activation depends on the interaction of a specific TLR ligand with its cognate TLR, independently of the connecting adapters or the cellular compartment where TLR signaling occurs. A RhoA FRET probe was used to examine localized RhoA activity at early time points after initiation of TLR2 or TLR3 signaling. After 3-5 min of treatment with the TLR2 ...

Cdc42 is a member of the Rho GTPase family and functions as a molecular switch in regulating cell migration, proliferation, differentiation and survival. However, the role of Cdc42 in heart development remains largely unknown. To determine the function of Cdc42 in heart formation, we have generated a Cdc42 cardiomyocyte knockout (CCKO) mouse line by crossing Cdc42 flox mice with myosin light chain (MLC) 2a-Cre mice. The inactivation of Cdc42 in embryonic cardiomyocytes induced lethality after embryonic day 12.5. Histological analysis of CCKO embryos showed cardiac developmental defects that included thin ventricular walls and ventricular septum defects. Microarray and real-time PCR data also revealed that the expression level of p21 was significantly increased and cyclin B1 was dramatically decreased, suggesting that Cdc42 is required for cardiomyocyte proliferation. Phosphorylated Histone H3 staining confirmed that the inactivation of Cdc42 inhibited cardiomyocytes proliferation. In addition,

Most previous studies on the activation of Rho-like GTPases have relied on analyses of downstream cytoskeletal changes. In the new study, Sander et al. took advantage of the properties of two downstream effectors, Pak and Rhotekin, to confer specificity in a biochemical assay for Rho-like GTPase activity. Pak binds to GTP-, but not GDP-loaded Rac and Cdc42, and Rhotekin binds specifically to GTP-loaded Rho. Activation of Rac, or signaling by constitutively active mutants of Cdc42 and Rac, down-regulates endogenous Rho activity, but activation of Rho has no effect on Rac activity. The down-regulation of Rho by Rac causes an epithelioid, nonmigratory phenotype in NIH3T3 fibroblasts, an effect that can be reversed by expressing constitutively active Rho, indicating that the reciprocal balance of the two proteins determines cell morphology and migratory behavior. The scientists found a similar down-regulation of Rho by Rac in several other cell types, and are now trying to identify factors that ...

To further test the vector system, we designed both a synthetic siRNA and a pSUPER vector that target the same 19-nt sequence in theCDC20 transcript. As for CDH1, efficient suppression of endogenous CDC20 expression was achieved with both synthetic siRNA and with pSUPER-CDC20 (Fig. 2B). To measure the level of gene suppression accurately by the pSUPER system, we designed a construct to target polo like kinase-1 (PLK1). Introduction of pSUPER-PLK1 led to a significant decrease in PLK1 protein levels and a reduction in PLK1 kinase activity by a factor of 10 [Supplementary fig. 1A (4)]. To date, we were successful in knocking down the expression of more than 10 genes for which we designed a pSUPER siRNA vector, highlighting the efficiency with which genes can be targeted using this vector (6).. Next, we asked whether suppression of gene expression by the pSUPER vector is sufficient to affect cellular physiology. We designed a construct to knockdown p53, a transcription factor that is stabilized ...

Vaccines are not enough, though, according to the government. Vaccinated people must also wear a mask indoors at all times if they hope to flatten the curve. Masking indoors regardless of vaccination status is the latest recommendation from Fauci and friends..
