    Genetic screens performed in worms identified major regulators of the epidermal growth factor receptor (EGFR) pathway, including the ubiquitin ligase Cbl/SLI-1. Here we focus on the less-characterized Lst2 protein and confirm suppression of MAPK signals. Unexpectedly, human Lst2, a monoubiquitinylated phosphoprotein, does not localize to endosomes, despite an intrinsic phosphoinositol-binding FYVE domain. By constructing an ubiquitinylation-defective mutant and an ubiquitin fusion, we conclude that endosomal localization of Lst2, along with an ability to divert incoming EGFR molecules to degradation in lysosomes, is regulated by ubiquitinylation/deubiquitinylation cycles. Consistent with bifurcating roles, Lst2 physically binds Trim3/BERP, which interacts with Hrs and a complex that biases cargo recycling. These results establish an ubiquitin-based endosomal switch of receptor sorting, functionally equivalent to the mechanism inactivating Hrs via monoubiquitinylation.

    Schizophrenia is a complex disease, likely to be caused by a combination of serial alterations in a number of genes and environmental factors. The dorsolateral prefrontal cortex (Brodmann's Area 46) is involved in schizophrenia and executes high-level functions such as working memory, differentiation of conflicting thoughts, determination of right and wrong concepts and attitudes, correct social behavior and personality expression. Global proteomic analysis of post-mortem dorsolateral prefrontal cortex samples from schizophrenia patients and non-schizophrenic individuals was performed using stable isotope labeling and shotgun proteomics. The analysis resulted in the identification of 1,261 proteins, 84 of which showed statistically significant differential expression, reinforcing previous data supporting the involvement of the immune system, calcium homeostasis, cytoskeleton assembly, and energy metabolism in schizophrenia. In addition a number of new potential markers were found that may contribute to the understanding of the pathogenesis of this complex disease.

    Background: Malignant gliomas are frequent primary brain tumors associated with poor prognosis and very limited response to conventional chemo- and radio-therapies. Besides sharing common growth features with other types of solid tumors, gliomas are highly invasive into adjacent brain tissue, which renders them particularly aggressive and their surgical resection inefficient. Therefore, insights into glioma formation are of fundamental interest in order to provide novel molecular targets for diagnostic purposes and potential anti-cancer drugs. Human Tripartite motif protein 3 (TRIM3) encodes a structural homolog of Drosophila brain tumor (brat) implicated in progenitor cell proliferation control and cancer stem cell suppression. TRIM3 is located within the loss of allelic heterozygosity (LOH) hotspot of chromosome segment 11p15.5, indicating a potential role in tumor suppression.

    Methods: Here we analyze 70 primary human gliomas of all types and grades and report somatic deletion mapping as well as single nucleotide polymorphism analysis together with quantitative real-time PCR of chromosome segment 11p15.5.

    Results: Our analysis identifies LOH in 17 cases (24%) of primary human glioma which defines a common 130 kb-wide interval within the TRIM3 locus as a minimal area of loss. We further detect altered genomic dosage of TRIM3 in two glioma cases with LOH at 11p15.5, indicating homozygous deletions of TRIM3.

    Conclusion: Loss of heterozygosity of chromosome segment 11p15.5 in malignant gliomas suggests TRIM3 as a candidate brain tumor suppressor gene.

    Cell signaling mechanisms often transmit information via posttranslational protein modifications, most importantly reversible protein phosphorylation. Here we develop and apply a general mass spectrometric technology for identification and quantitation of phosphorylation sites as a function of stimulus, time, and subcellular location. We have detected 6,600 phosphorylation sites on 2,244 proteins and have determined their temporal dynamics after stimulating HeLa cells with epidermal growth factor (EGF) and recorded them in the Phosida database. Fourteen percent of phosphorylation sites are modulated at least 2-fold by EGF, and these were classified by their temporal profiles. Surprisingly, a majority of proteins contain multiple phosphorylation sites showing different kinetics, suggesting that they serve as platforms for integrating signals. In addition to protein kinase cascades, the targets of reversible phosphorylation include ubiquitin ligases, guanine nucleotide exchange factors, and at least 46 different transcriptional regulators. The dynamic phosphoproteome provides a missing link in a global, integrative view of cellular regulation.

  • CART: an Hrs/actinin-4/BERP/myosin V protein complex required for efficient receptor recycling.

    Altering the number of surface receptors can rapidly modulate cellular responses to extracellular signals. Some receptors, like the transferrin receptor (TfR), are constitutively internalized and recycled to the plasma membrane. Other receptors, like the epidermal growth factor receptor (EGFR), are internalized after ligand binding and then ultimately degraded in the lysosome. Routing internalized receptors to different destinations suggests that distinct molecular mechanisms may direct their movement. Here, we report that the endosome-associated protein hrs is a subunit of a protein complex containing actinin-4, BERP, and myosin V that is necessary for efficient TfR recycling but not for EGFR degradation. The hrs/actinin-4/BERP/myosin V (CART [cytoskeleton-associated recycling or transport]) complex assembles in a linear manner and interrupting binding of any member to its neighbor produces an inhibition of transferrin recycling rate. Disrupting the CART complex results in shunting receptors to a slower recycling pathway that involves the recycling endosome. The novel CART complex may provide a molecular mechanism for the actin-dependence of rapid recycling of constitutively recycled plasma membrane receptors.

    As a base for human transcriptome and functional genomics, we created the "full-length long Japan" (FLJ) collection of sequenced human cDNAs. We determined the entire sequence of 21,243 selected clones and found that 14,490 cDNAs (10,897 clusters) were unique to the FLJ collection. About half of them (5,416) seemed to be protein-coding. Of those, 1,999 clusters had not been predicted by computational methods. The distribution of GC content of nonpredicted cDNAs had a peak at approximately 58% compared with a peak at approximately 42%for predicted cDNAs. Thus, there seems to be a slight bias against GC-rich transcripts in current gene prediction procedures. The rest of the cDNAs unique to the FLJ collection (5,481) contained no obvious open reading frames (ORFs) and thus are candidate noncoding RNAs. About one-fourth of them (1,378) showed a clear pattern of splicing. The distribution of GC content of noncoding cDNAs was narrow and had a peak at approximately 42%, relatively low compared with that of protein-coding cDNAs.

  • E3 ligase activity of RING finger proteins that interact with Hip-2, a human ubiquitin-conjugating enzyme.

    Graduate School of Biotechnology, Korea University, Seoul, South Korea.

    To identify proteins that interact with Huntingtin-interacting protein-2 (Hip-2), a ubiquitin-conjugating enzyme, a yeast two-hybrid screen system was used to isolate five positive clones. Sequence analyses showed that, with one exception, all Hip-2-interacting proteins contained the RING finger motifs. The interaction of Hip-2 with RNF2, one of the clones, was further confirmed through in vitro and in vivo experiments. Mutations in the RING domain of RNF2 prevented the clone from binding to Hip-2, an indication that the RING domain is the binding determinant. RNF2 showed a ubiquitin ligase (E3) activity in the presence of Hip-2, suggesting that a subset of RING finger proteins may have roles as E3s.

    A functional genomic approach, based on systematic data gathering, was used to characterize a family of proteins containing a tripartite motif (TRIM). A total of 37 TRIM genes/proteins were studied, 21 of which were novel. The results demonstrate that TRIM proteins share a common function: by means of homo-multimerization they identify specific cell compartments.

  • Cloning and characterization of a gene (RNF22) encoding a novel brain expressed ring finger protein (BERP) that maps to human chromosome 11p15.5.

    We have recently identified a novel RING finger protein expressed in the rat brain, which associates with myosin V and alpha-actinin-4. Here we have cloned and characterized the orthologous human BERP cDNA and gene (HGMW-approved symbol RNF22). The human BERP protein is encoded by 11 exons ranging in size from 71 to 733 bp, and fluorescence in situ hybridization shows that the BERP gene maps to chromosome 11p15.5, 3' to the FE65 gene. The human BERP protein is 98% identical to the rat and mouse proteins, and we have identified a highly conserved potential orthologue in Caenorhabditis elegans. BERP belongs to the RING finger-B-box-coiled coil (RBCC) subgroup of RING finger proteins, and a cluster of these RBCC protein genes is present in chromosome 11p15. Chromosome region 11p15 is thought to harbor tumor suppressor genes, and deletions of this region occur frequently in several types of human cancers. These observations indicate that BERP may be a novel tumor suppressor gene.

  • BERP, a novel ring finger protein, binds to alpha-actinin-4.

    Graduate Program in Neuroscience, Department of Psychiatry, University of British Columbia, Vancouver, British Columbia, V6T 1Z3, Canada.

    We recently identified BERP as a novel RING finger protein belonging to the RBCC protein family. It contains an N-terminal RING finger, followed by a B-box zinc finger and a coiled-coil domain. BERP interacts with the tail domain of the class V myosins through a beta-propeller structure in the BERP C-terminal. To identify other proteins interacting with BERP, the yeast two-hybrid strategy was employed, using the RBCC domain as bait. Screening of a rat brain cDNA library identified alpha-actinin-4 as a specific binding partner for the N-terminus of BERP. This actinin isoform could be immunoprecipitated together with BERP from HEK 293 cells transfected with expression constructs for BERP and alpha-actinin-4. These proteins could also be colocalized immunohistochemically in the cytoplasm of differentiated PC12 cells. We suggest that BERP may anchor class V myosins to particular cell domains via its interaction with alpha-actinin-4.

  • Cloning and characterization of a novel RING finger protein that interacts with class V myosins.

    El-Husseini AE and Vincent SR

    Graduate Program in Neuroscience, Department of Psychiatry, University of British Columbia, Vancouver, British Columbia V6T 1Z3, Canada.

    We have identified a novel protein (BERP) that is a specific partner for the tail domain of myosin V. Class V myosins are a family of molecular motors thought to interact via their unique C-terminal tails with specific proteins for the targeted transport of organelles. BERP is highly expressed in brain and contains an N-terminal RING finger, followed by a B-box zinc finger, a coiled-coil (RBCC domain), and a unique C-terminal beta-propeller domain. A yeast two-hybrid screening indicated that the C-terminal beta-propeller domain mediates binding to the tail of the class V myosin myr6 (myosin Vb). This interaction was confirmed by immunoprecipitation, which also demonstrated that BERP could associate with myosin Va, the product of the dilute gene. Like myosin Va, BERP is expressed in a punctate pattern in the cytoplasm as well as in the neurites and growth cones of PC12 cells. We also found that the RBCC domain of BERP is involved in protein dimerization. Stable expression of a mutant form of BERP lacking the myosin-binding domain but containing the dimerization domain resulted in defective PC12 cell spreading and prevented neurite outgrowth in response to nerve growth factor. Our studies present a novel interaction for the beta-propeller domain and provide evidence for a role for BERP in myosin V-mediated cargo transport.
