Here we investigate nuclear import of U1A and U2B′′ in vitro and demonstrate that it occurs by an active, saturable process. Several lines of evidence suggest that import of the two proteins occurs by an import mechanism different to those characterized previously. No cross competition is seen with a variety of previously studied NLSs. In contrast to import mediated by members of the importin-β family of nucleocytoplasmic transport receptors, U1A/U2B′′ import is not inhibited by either nonhydrolyzable guanosine triphosphate (GTP) analogues or by a mutant of the GTPase Ran that is incapable of GTP hydrolysis. Adenosine triphosphate is capable of supporting U1A and U2B′′ import, whereas neither nonhydrolyzable adenosine triphosphate analogues nor GTP can do so. U1A and U2B′′ import in vitro does not require the addition of soluble cytosolic proteins, but a factor or factors required for U1A and U2B′′ import remains tightly associated with the nuclear fraction of conventionally permeabilized cells. This activity can be solubilized in the presence of elevated MgCl2. These data suggest that U1A and U2B′′ import into the nucleus occurs by a hitherto uncharacterized mechanism."}],"doi":"10.1083/jcb.148.2.293","extern":"1","intvolume":" 148","language":[{"iso":"eng"}],"external_id":{"pmid":["10648562"]},"_id":"11126","issue":"2","citation":{"short":"M.

Identification of mirrored hosts can improve Web-based information retrieval in several ways: first, by identifying mirrored hosts, search engines can avoid storing and returning duplicate documents. Second, several new information retrieval techniques for the Web make inferences based on the explicit links among hypertext documents—mirroring perturbs their graph model and degrades performance. Third, mirroring information can be used to redirect users to alternate mirror sites to compensate for various failures, and can thus improve the performance of Web browsers and proxies.

These receptors are linked to several intracellular signal transduction mechanisms via G-protein and are implicated in diverse functions of the mammalian central nervous system (CNS). These functions include mediation of slow excitatory and inhibitory responses; regulation of calcium channels, potassium channels, and non-selective cation channels; inhibition and facilitation of transmitter release; induction of long-term potentiation and long-term depression; and regulation of neuronal development. Functional diversity of the metabotropic glutamate receptor is reflected in molecular diversity of receptor subtypes. The sites of action of mGluRs are widely found throughout different membrane compartments of neuronal and glial cells. The chapter reviews the differential subcellular localization of metabotropic glutamate receptors in relation to transmitter release sites. Patterns of subcellular localization of mGluRs are different among three subgroups: group I and III mGluRs are mainly localized to somatodendritic and axonal domains of neurons, respectively, while group II mGluRs are extensively localized to both domains as well as to glial cell processes.","lang":"eng"}],"author":[{"full_name":"Shigemoto, Ryuichi","last_name":"Shigemoto","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8761-9444","first_name":"Ryuichi"},{"first_name":"Noboru","last_name":"Mizuno","full_name":"Mizuno, Noboru"}],"page":"63 - 98","quality_controlled":"1","_id":"2494","publication_identifier":{"eissn":["0924-8196"]},"language":[{"iso":"eng"}],"user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","publication":"Glutamate","publication_status":"published","publist_id":"4407","intvolume":" 18","status":"public"},{"volume":342,"year":"2000","month":"01","publisher":"Massachussetts Medical Society","pmid":1,"fulldoi":"https://doi.org/10.1056/NEJM200001063420104","main_file_link":[{"open_access":"1","url":"https://www.nejm.org/doi/full/10.1056/nejm200001063420104"}],"date_updated":"2023-05-03T11:14:19Z","external_id":{"pmid":["10620645"]},"language":[{"iso":"eng"}],"oa":1,"intvolume":" 342","publist_id":"4300","_id":"2598","issue":"1","page":"21 - 27","author":[{"full_name":"Sillevis Smitt, Peter","last_name":"Sillevis Smitt","first_name":"Peter"},{"last_name":"Kinoshita","first_name":"Ayae","full_name":"Kinoshita, Ayae"},{"last_name":"De Leeuw","first_name":"Bertie","full_name":"De Leeuw, Bertie"},{"full_name":"Moll, Wiebe","last_name":"Moll","first_name":"Wiebe"},{"full_name":"Coesmans, Michiel","last_name":"Coesmans","first_name":"Michiel"},{"full_name":"Jaarsma, Dick","last_name":"Jaarsma","first_name":"Dick"},{"first_name":"Sonja","last_name":"Henzen Logmans","full_name":"Henzen Logmans, Sonja"},{"full_name":"Vecht, Charles","last_name":"Vecht","first_name":"Charles"},{"first_name":"Chris","last_name":"De Zeeuw","full_name":"De Zeeuw, Chris"},{"last_name":"Sekiyama","first_name":"Naotaka","full_name":"Sekiyama, Naotaka"},{"first_name":"Shigetada","last_name":"Nakanishi","full_name":"Nakanishi, Shigetada"},{"last_name":"Shigemoto","orcid":"0000-0001-8761-9444","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","first_name":"Ryuichi","full_name":"Shigemoto, Ryuichi"}],"extern":"1","doi":"10.1056/NEJM200001063420104","abstract":[{"lang":"eng","text":"There are many types of cerebellar ataxia, including ataxia due to congenital or metabolic disorders and a paraneoplastic form in patients with gynecologic cancer, breast cancer, lung cancer, or Hodgkin's disease.1 This paraneoplastic syndrome is the only type of cerebellar ataxia associated with autoantibodies against neuronal antigens. Often, the neuronal antigens are aberrantly expressed by the tumor cells.2-4 The antineuronal autoantibodies are believed to cause cerebellar ataxia, but this is unproved.5,6 In Hodgkin's disease, the lymphoma precedes the ataxia by months to years in 80 percent of patients, and ataxia often occurs during a prolonged complete remission.4 Among patients with this type of ataxia, 30 percent have anti–Purkinje-cell antibodies, some of which have the features of the neuronal antibody anti-Tr.4,7\r\n\r\nWe identified a new autoantibody in two patients with severe cerebellar ataxia that developed while they were in remission from Hodgkin's disease. The antibody reacts specifically with the metabotropic glutamate receptor mGluR1 in mouse brain. Metabotropic glutamate receptors belong to a large family of cell-surface receptors that transmit signals into the cell by coupling to guanine nucleotide-binding proteins (G proteins) in the cytoplasm. Purified IgG from the serum of both patients blocked the glutamate-stimulated formation of inositol phosphates in Chinese-hamster-ovary (CHO) cells that expressed mGluR1α, and the injection of IgG from serum or cerebrospinal fluid into the cerebellar subarachnoid space of mice caused severe, reversible ataxia. These results indicate that antineuronal autoantibodies can cause disease of the central nervous system by blocking neuronal receptors."}],"article_processing_charge":"No","article_type":"original","scopus_import":"1","day":"06","date_created":"2018-12-11T11:58:35Z","type":"journal_article","acknowledgement":"Supported in part by the Ministry of Education, Science, and Culture of Japan (Dr. Nakanishi and Dr. Shigemoto); CREST of Japan Science and Technology Corporation (Dr. Shigemoto); the Life Sciences Foundation (Dr. De Zeeuw); NWO (Dr. De Zeeuw and Dr. De Leeuw); and the Human Frontier Science Program (Dr. De Zeeuw and Dr. Shigemoto).\r\nDrs.

This allowed us to study the effect of the transfected receptor on somatic Ca2+ channels. In transfected neurons, mGuR7 selectively inhibited P/Q-type Ca2+ channels. The effect was mimicked by GTPγS and blocked by pertussis toxin (PTX) or a selective antibody raised against the G-protein αo subunit, indicating the involvement of a G(o)-like protein. The mGuR7 effect did not display the characteristics of a direct interaction between G-protein βγ subunits and the α1A Ca2+ channel subunit, but was abolished by quenching βγ subunits with specific intracellular peptides. Intracellular dialysis of G-protein βγ subunits did not mimic the action of mGluR7, suggesting that both G-protein βγ and αo subunits were required to mediate the effect. Inhibition of phospholipase C (PLC) blocked the inhibitory action of mGluR7, suggesting that a coincident activation of PLC by the G-protein βγ with αo subunits was required. The Ca2+ chelator BAPTA, as well as inhibition of either the inositol trisphosphate (IP3) receptor or protein kinase C (PKC) abolished the mGluR7 effect. Moreover, activation of native mGluR7 induced a PTX-dependent IP3 formation. These results indicated that IP3-mediated intracellular Ca2+ release was required for PKC-dependent inhibition of the Ca2+ channels. Possible control of synaptic transmission by the present mechanisms is discussed."}],"doi":"10.1523/JNEUROSCI.20-21-07896.2000","extern":"1","author":[{"first_name":"Julie","last_name":"Perroy","full_name":"Perroy, Julie"},{"last_name":"Prezèau","first_name":"Laurent","full_name":"Prezèau, Laurent"},{"first_name":"Michel","last_name":"De Waard","full_name":"De Waard, Michel"},{"full_name":"Shigemoto, Ryuichi","first_name":"Ryuichi","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8761-9444","last_name":"Shigemoto"},{"first_name":"Joël","last_name":"Bockaërt","full_name":"Bockaërt, Joël"},{"last_name":"Fagni","first_name":"Laurent","full_name":"Fagni, Laurent"}],"page":"7896 - 7904","main_file_link":[{"open_access":"1","url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6772734/"}],"fulldoi":"https://doi.org/10.1523/JNEUROSCI.20-21-07896.2000","pmid":1,"month":"11","year":"2000","publisher":"Society for Neuroscience","volume":20,"date_updated":"2023-05-03T09:48:17Z","publication_identifier":{"issn":["0270-6474"]},"publication":"Journal of Neuroscience","publication_status":"published","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","status":"public","date_published":"2000-11-01T00:00:00Z","oa_version":"Published Version","title":"Selective blockade of P/Q-type calcium channels by the metabotropic glutamate receptor type 7 involves a phospholipase C pathway in neurons","quality_controlled":"1","type":"journal_article","date_created":"2018-12-11T11:58:37Z","day":"01","scopus_import":"1","article_type":"original","citation":{"short":"J.

In contrast to the wealth of information about postsynaptic specializations, little is known about the molecular organization of presynaptic membrane proteins. We show here that the metabotropic glutamate receptor mGluR7a, which localizes specifically to presynaptic active zones, interacts in vitro and in vivo with PICK1. Coexpression in heterologous systems induces coclustering dependent upon the extreme C terminus of mGluR7a and the PDZ domain of PICK1. mGluR7a and PICK1 localize to excitatory synapses in hippocampal neurons. Furthermore, whereas transfected mGluR7a clusters at presynaptic sites, mGluR7aΔ3 lacking the PICK1 binding site targets to axons but does not cluster. These results suggest that PICK1 is a component of the presynaptic machinery involved in mGlUR7a aggregation and in modulation of glutamate neurotransmission."}],"article_processing_charge":"No","doi":"10.1016/S0896-6273(00)00127-6","extern":"1","page":"485 - 497","author":[{"first_name":"Hélène","last_name":"Boudin","full_name":"Boudin, Hélène"},{"full_name":"Doan, Andrew","first_name":"Andrew","last_name":"Doan"},{"full_name":"Xia, Jun","last_name":"Xia","first_name":"Jun"},{"full_name":"Shigemoto, Ryuichi","orcid":"0000-0001-8761-9444","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","first_name":"Ryuichi","last_name":"Shigemoto"},{"full_name":"Huganir, Richard","last_name":"Huganir","first_name":"Richard"},{"last_name":"Worley","first_name":"Paul","full_name":"Worley, Paul"},{"full_name":"Craig, Ann","first_name":"Ann","last_name":"Craig"}],"issue":"2","_id":"2603","intvolume":" 28","publist_id":"4295","external_id":{"pmid":["11144358"]},"language":[{"iso":"eng"}],"date_updated":"2023-05-03T09:41:55Z","pmid":1,"fulldoi":"https://doi.org/10.1016/S0896-6273(00)00127-6","volume":28,"year":"2000","publisher":"Elsevier","month":"11","date_published":"2000-11-01T00:00:00Z","oa_version":"None","title":"Presynaptic clustering of mGluR7a requires the PICK1 PDZ domain binding site","quality_controlled":"1","publication_identifier":{"issn":["0896-6273"]},"status":"public","publication_status":"published","publication":"Neuron","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","citation":{"short":"H.
