    Beschreibung: The cyclin-dependent kinase 4 (CDK4) regulates progression through the G1 phase of the cell cycle. The activity of CDK4 is controlled by the opposing effects of the D-type cyclin, an activating subunit, and p16INK4, an inhibitory subunit. Ectopic expression of p16INK4 blocked entry into S phase of the cell cycle induced by oncogenic Ha-Ras, and this block was relieved by coexpression of a catalytically inactive CDK4 mutant. Expression of p16INK4 suppressed cellular transformation of primary rat embryo fibroblasts by oncogenic Ha-Ras and Myc, but not by Ha-Ras and E1a. Together, these observations provide direct evidence that p16INK4 can inhibit cell growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Serrano, M -- Gomez-Lahoz, E -- DePinho, R A -- Beach, D -- Bar-Sagi, D -- CA55360/CA/NCI NIH HHS/ -- EY09300-01/EY/NEI NIH HHS/ -- HD28317-02/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1995 Jan 13;267(5195):249-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Cold Spring Harbor Laboratory, NY 11724.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7809631" target="_blank"〉PubMed〈/a〉

    Beschreibung: DCoH, the dimerization cofactor of hepatocyte nuclear factor-1, stimulates gene expression by associating with specific DNA binding proteins and also catalyzes the dehydration of the biopterin cofactor of phenylalanine hydroxylase. The x-ray crystal structure determined at 3 angstrom resolution reveals that DCoH forms a tetramer containing two saddle-shaped grooves that comprise likely macromolecule binding sites. Two equivalent enzyme active sites flank each saddle, suggesting that there is a spatial connection between the catalytic and binding activities. Structural similarities between the DCoH fold and nucleic acid-binding proteins argue that the saddle motif has evolved to bind diverse ligands or that DCoH unexpectedly may bind nucleic acids.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Endrizzi, J A -- Cronk, J D -- Wang, W -- Crabtree, G R -- Alber, T -- New York, N.Y. -- Science. 1995 Apr 28;268(5210):556-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley 94720-3206, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7725101" target="_blank"〉PubMed〈/a〉

    Beschreibung: Furosemide, a chloride cotransport inhibitor, reversibly blocked synchronized burst discharges in hippocampal slices without reducing the pyramidal cell response to single electrical stimuli. Images of the intrinsic optical signal acquired during these slice experiments indicated that furosemide coincidentally blocked changes in extracellular space. In urethane-anesthetized rats, systemically injected furosemide blocked kainic acid-induced electrical discharges recorded from cortex. These results suggest that (i) neuronal synchronization involved in epileptiform activity can be dissociated from synaptic excitability; (ii) nonsynaptic mechanisms, possibly associated with furosemide-sensitive cell volume regulation, may be critical for synchronization of neuronal activity; and (iii) agents that affect extracellular volume may have clinical utility as antiepileptic drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hochman, D W -- Baraban, S C -- Owens, J W -- Schwartzkroin, P A -- NS07144/NS/NINDS NIH HHS/ -- NS15317/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1995 Oct 6;270(5233):99-102.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurological Surgery, University of Washington, Seattle 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7569957" target="_blank"〉PubMed〈/a〉

    Beschreibung: Receptor-mediated activation of heterotrimeric guanine nucleotide-binding proteins (G proteins) results in the dissociation of alpha from beta gamma subunits, thereby allowing both to regulate effectors. Little is known about the regions of effectors required for recognition of G beta gamma. A peptide encoding residues 956 to 982 of adenylyl cyclase 2 specifically blocked G beta gamma stimulation of adenylyl cyclase 2, phospholipase C-beta 3, potassium channels, and beta-adrenergic receptor kinase as well as inhibition of calmodulin-stimulated adenylyl cyclases, but had no effect on interactions between G beta gamma and G alpha o. Substitutions in this peptide identified a functionally important motif, Gln-X-X-Glu-Arg, that is also conserved in regions of potassium channels and beta-adrenergic receptor kinases that participate in G beta gamma interactions. Thus, the region defined by residues 956 to 982 of adenylyl cyclase 2 may contain determinants important for receiving signals from G beta gamma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, J -- DeVivo, M -- Dingus, J -- Harry, A -- Li, J -- Sui, J -- Carty, D J -- Blank, J L -- Exton, J H -- Stoffel, R H -- CA-44998/CA/NCI NIH HHS/ -- DK-37219/DK/NIDDK NIH HHS/ -- DK-38761/DK/NIDDK NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1995 May 26;268(5214):1166-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Mount Sinai School of Medicine, City University of New York, NY 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7761832" target="_blank"〉PubMed〈/a〉

    Beschreibung: Whether neurons express major histocompatibility complex (MHC) class I genes has not been firmly established. The techniques of confocal laser microscopy, patch clamp electrophysiology, and reverse transcriptase-polymerase chain reaction were combined here to directly examine the inducibility of MHC class I genes in individual cultured rat hippocampal neurons. Transcription of MHC class I genes was very rare in neurons with spontaneous action potentials. In electrically silent neurons, transcription was noted, with expression of beta 2-microglobulin under tighter control than in class I heavy chain molecules. Surface expression of class I molecules occurred only in electrically silent neurons treated with interferon gamma. Immunosurveillance by cytotoxic T cells may be focused on functionally impaired neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Neumann, H -- Cavalie, A -- Jenne, D E -- Wekerle, H -- New York, N.Y. -- Science. 1995 Jul 28;269(5223):549-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroimmunology, Max Planck Institute for Psychiatry, Martinsried, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624779" target="_blank"〉PubMed〈/a〉

    Beschreibung: Activation of dendritic voltage-gated ion channels by local synaptic input was tested by simultaneous dendrite-attached patch-clamp recordings and whole-cell somatic voltage recordings made from CA1 pyramidal neurons in hippocampal slices. Schaffer collateral stimulation elicited subthreshold excitatory postsynaptic potentials (EPSPs) that opened voltage-gated sodium and calcium channels in the apical dendrites. The EPSP-activated sodium channels opened near the peak of the EPSP, whereas low voltage-activated calcium channels opened near the EPSP peak and during the decay phase. Dendritic high voltage-activated channels required somatic action potential generation or suprathreshold synaptic trains for activation. Dendritic voltage-gated channels are, therefore, likely to participate in dendritic integration of synaptic events.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Magee, J C -- Johnston, D -- MH44754/MH/NIMH NIH HHS/ -- NS09482/NS/NINDS NIH HHS/ -- NS11535/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1995 Apr 14;268(5208):301-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neuroscience, Baylor College of Medicine, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7716525" target="_blank"〉PubMed〈/a〉

    Beschreibung: Fluorescent probes offer insight into the highly localized and rapid molecular events that underlie cell function. However, methods are required that can efficiently transform the limited signals from such probes into high-resolution images. An algorithm has now been developed that produces highly accurate images of fluorescent probe distribution inside cells with minimal light exposure and a conventional light microscope. This method provides resolution nearly four times greater than that currently available from any fluorescence microscope and was used to study several biological problems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carrington, W A -- Lynch, R M -- Moore, E D -- Isenberg, G -- Fogarty, K E -- Fay, F S -- New York, N.Y. -- Science. 1995 Jun 9;268(5216):1483-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Molecular Medicine, University of Massachusetts Medical School, Worcester 01605, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7770772" target="_blank"〉PubMed〈/a〉

    Beschreibung: Specificity of protein kinases and phosphatases may be achieved through compartmentalization with preferred substrates. In neurons, adenosine 3', 5'-monophosphate (cAMP)-dependent protein kinase (PKA) is localized at postsynaptic densities by association of its regulatory subunit with an A kinase anchor protein, AKAP79. Interaction cloning experiments demonstrated that AKAP79 also binds protein phosphatase 2B, or calcineurin (CaN). A ternary complex of PKA, AKAP, and CaN was isolated from bovine brain, and colocalization of the kinase and the phosphatase was established in neurites of cultured hippocampal neurons. The putative CaN-binding domain of AKAP79 is similar to that of the immunophilin FKBP-12, and AKAP79 inhibited CaN phosphatase activity. These results suggest that both PKA and CaN are targeted to subcellular sites by association with a common anchor protein and thereby regulate the phosphorylation state of key neuronal substrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coghlan, V M -- Perrino, B A -- Howard, M -- Langeberg, L K -- Hicks, J B -- Gallatin, W M -- Scott, J D -- DK09059/DK/NIDDK NIH HHS/ -- GM48231/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Jan 6;267(5194):108-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vollum Institute, Oregon Health Sciences University, Portland 97201.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7528941" target="_blank"〉PubMed〈/a〉

    Beschreibung: Hydrolysis of guanosine triphosphate (GTP) by the small guanosine triphosphatase (GTPase) adenosine diphosphate ribosylation factor-1 (ARF1) depends on a GTPase-activating protein (GAP). A complementary DNA encoding the ARF1 GAP was cloned from rat liver and predicts a protein with a zinc finger motif near the amino terminus. The GAP function required an intact zinc finger and additional amino-terminal residues. The ARF1 GAP was localized to the Golgi complex and was redistributed into a cytosolic pattern when cells were treated with brefeldin A, a drug that prevents ARF1-dependent association of coat proteins with the Golgi. Thus, the GAP is likely to be recruited to the Golgi by an ARF1-dependent mechanism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cukierman, E -- Huber, I -- Rotman, M -- Cassel, D -- New York, N.Y. -- Science. 1995 Dec 22;270(5244):1999-2002.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Technion-Israel Institute of Technology, Haifa, Israel.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8533093" target="_blank"〉PubMed〈/a〉
