    Description: Mechanical and thermal cues stimulate a specialized group of sensory neurons that terminate in the skin. Three members of the transient receptor potential (TRP) family of channels are expressed in subsets of these neurons and are activated at distinct physiological temperatures. Here, we describe the cloning and characterization of a novel thermosensitive TRP channel. TRPV3 has a unique threshold: It is activated at innocuous (warm) temperatures and shows an increased response at noxious temperatures. TRPV3 is specifically expressed in keratinocytes; hence, skin cells are capable of detecting heat via molecules similar to those in heat-sensing neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peier, Andrea M -- Reeve, Alison J -- Andersson, David A -- Moqrich, Aziz -- Earley, Taryn J -- Hergarden, Anne C -- Story, Gina M -- Colley, Sian -- Hogenesch, John B -- McIntyre, Peter -- Bevan, Stuart -- Patapoutian, Ardem -- New York, N.Y. -- Science. 2002 Jun 14;296(5575):2046-9.

    Description: The Agrobacterium VirB/D4 transport system mediates the transfer of a nucleoprotein T complex into plant cells, leading to crown gall disease. In addition, several Virulence proteins must somehow be transported to fulfill a function in planta. Here, we used fusions between Cre recombinase and VirE2 or VirF to directly demonstrate protein translocation into plant cells. Transport of the proteins was monitored by a Cre-mediated in planta recombination event resulting in a selectable phenotype and depended on the VirB/D4 transport system but did not require transferred DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vergunst, A C -- Schrammeijer, B -- den Dulk-Ras, A -- de Vlaam, C M -- Regensburg-Tuink, T J -- Hooykaas, P J -- New York, N.Y. -- Science. 2000 Nov 3;290(5493):979-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Molecular Plant Sciences, Leiden University, Clusius Laboratory, Wassenaarseweg 64, 2333 AL, Leiden, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11062129" target="_blank"〉PubMed〈/a〉

    Description: Cadherins are transmembrane proteins that mediate adhesion between cells in the solid tissues of animals. Here we present the 3.1 angstrom resolution crystal structure of the whole, functional extracellular domain from C-cadherin, a representative "classical" cadherin. The structure suggests a molecular mechanism for adhesion between cells by classical cadherins, and it provides a new framework for understanding both cis (same cell) and trans (juxtaposed cell) cadherin interactions. The trans adhesive interface is a twofold symmetric interaction defined by a conserved tryptophan side chain at the membrane-distal end of a cadherin molecule from one cell, which inserts into a hydrophobic pocket at the membrane-distal end of a cadherin molecule from the opposing cell.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boggon, Titus J -- Murray, John -- Chappuis-Flament, Sophie -- Wong, Ellen -- Gumbiner, Barry M -- Shapiro, Lawrence -- NCI-P30-CA-08784/CI/NCPDCID CDC HHS/ -- R01 GM062270/GM/NIGMS NIH HHS/ -- R01 GM52717/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2002 May 17;296(5571):1308-13.

    Description: Phenotypic variation among organisms is central to evolutionary adaptations underlying natural and artificial selection, and also determines individual susceptibility to common diseases. These types of complex traits pose special challenges for genetic analysis because of gene-gene and gene-environment interactions, genetic heterogeneity, low penetrance, and limited statistical power. Emerging genome resources and technologies are enabling systematic identification of genes underlying these complex traits. We propose standards for proof of gene discovery in complex traits and evaluate the nature of the genes identified to date. These proof-of-concept studies demonstrate the insights that can be expected from the accelerating pace of gene discovery in this field.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Glazier, Anne M -- Nadeau, Joseph H -- Aitman, Timothy J -- New York, N.Y. -- Science. 2002 Dec 20;298(5602):2345-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Physiological Genomics and Medicine Group, MRC Clinical Sciences Centre, Hammersmith Hospital, Imperial College Faculty of Medicine, Ducane Road, London W12 0NN, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12493905" target="_blank"〉PubMed〈/a〉

    Description: Dysfunction of the tubby protein results in maturity-onset obesity in mice. Tubby has been implicated as a transcription regulator, but details of the molecular mechanism underlying its function remain unclear. Here we show that tubby functions in signal transduction from heterotrimeric GTP-binding protein (G protein)-coupled receptors. Tubby localizes to the plasma membrane by binding phosphatidylinositol 4,5-bisphosphate through its carboxyl terminal "tubby domain." X-ray crystallography reveals the atomic-level basis of this interaction and implicates tubby domains as phosphorylated-phosphatidyl- inositol binding factors. Receptor-mediated activation of G protein alphaq (Galphaq) releases tubby from the plasma membrane through the action of phospholipase C-beta, triggering translocation of tubby to the cell nucleus. The localization of tubby-like protein 3 (TULP3) is similarly regulated. These data suggest that tubby proteins function as membrane-bound transcription regulators that translocate to the nucleus in response to phosphoinositide hydrolysis, providing a direct link between G-protein signaling and the regulation of gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Santagata, S -- Boggon, T J -- Baird, C L -- Gomez, C A -- Zhao, J -- Shan, W S -- Myszka, D G -- Shapiro, L -- New York, N.Y. -- Science. 2001 Jun 15;292(5524):2041-50.

    Description: The ability of intestinal mucosa to absorb dietary ferric iron is attributed to the presence of a brush-border membrane reductase activity that displays adaptive responses to iron status. We have isolated a complementary DNA, Dcytb (for duodenal cytochrome b), which encoded a putative plasma membrane di-heme protein in mouse duodenal mucosa. Dcytb shared between 45 and 50% similarity to the cytochrome b561 family of plasma membrane reductases, was highly expressed in the brush-border membrane of duodenal enterocytes, and induced ferric reductase activity when expressed in Xenopus oocytes and cultured cells. Duodenal expression levels of Dcytb messenger RNA and protein were regulated by changes in physiological modulators of iron absorption. Thus, Dcytb provides an important element in the iron absorption pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McKie, A T -- Barrow, D -- Latunde-Dada, G O -- Rolfs, A -- Sager, G -- Mudaly, E -- Mudaly, M -- Richardson, C -- Barlow, D -- Bomford, A -- Peters, T J -- Raja, K B -- Shirali, S -- Hediger, M A -- Farzaneh, F -- Simpson, R J -- New York, N.Y. -- Science. 2001 Mar 2;291(5509):1755-9.

    Description: Small molecules that affect specific protein functions can be valuable tools for dissecting complex cellular processes. Peptidoglycan synthesis and degradation is a process in bacteria that involves multiple enzymes under strict temporal and spatial regulation. We used a set of small molecules that inhibit the transglycosylation step of peptidoglycan synthesis to discover genes that help to regulate this process. We identified a gene responsible for the susceptibility of Escherichia coli cells to killing by glycolipid derivatives of vancomycin, thus establishing a genetic basis for activity differences between these compounds and vancomycin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eggert, U S -- Ruiz, N -- Falcone, B V -- Branstrom, A A -- Goldman, R C -- Silhavy, T J -- Kahne, D -- New York, N.Y. -- Science. 2001 Oct 12;294(5541):361-4.

    Description: In mammals, fertilization typically involves the ovulation of one or a few eggs at one end of the female reproductive tract and the entry of millions of sperm at the other. Given this disparity in numbers, it might be expected that the more precious commodity-eggs-would be subject to more stringent quality-control mechanisms. However, information from engineered mutations of meiotic genes suggests just the opposite. Specifically, the available mutants demonstrate striking sexual dimorphism in response to meiotic disruption; for example, faced with adversity, male meiosis grinds to a halt, whereas female meiosis soldiers on. This female "robustness" comes with a cost, however, because aneuploidy appears to be increased in the resultant oocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hunt, Patricia A -- Hassold, Terry J -- HD21341/HD/NICHD NIH HHS/ -- HD31866/HD/NICHD NIH HHS/ -- HD37502/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2002 Jun 21;296(5576):2181-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Case Western Reserve University, Cleveland, OH 44106-4955, USA. pah13@po.cwru.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12077403" target="_blank"〉PubMed〈/a〉

    Description: Lamellipodia are thin, veil-like extensions at the edge of cells that contain a dynamic array of actin filaments. We describe an approach for analyzing spatial regulation of actin polymerization and depolymerization in vivo in which we tracked single molecules of actin fused to the green fluorescent protein. Polymerization and the lifetime of actin filaments in lamellipodia were measured with high spatial precision. Basal polymerization and depolymerization occurred throughout lamellipodia with largely constant kinetics, and polymerization was promoted within one micron of the lamellipodium tip. Most of the actin filaments in the lamellipodium were generated by polymerization away from the tip.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watanabe, Naoki -- Mitchison, Timothy J -- GM48027/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2002 Feb 8;295(5557):1083-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Harvard Medical School, Boston, MA 02115, USA. naoki_watanabe@hms.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11834838" target="_blank"〉PubMed〈/a〉
