    Regulation of vegetative phase change in Arabidopsis thaliana by cyclophilin 40 (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-03-27
    Description: During its development, a plant shoot progresses from a juvenile to an adult phase of vegetative growth and from a reproductively incompetent to a reproductively competent state. In Arabidopsis, loss-of-function mutations in SQUINT (SQN) reduced the number of juvenile leaves and had subtle effects on inflorescence morphology but had no effect on flowering time or on reproductive competence. SQN encodes the Arabidopsis homolog of cyclophilin 40 (CyP40), a protein found in association with the Hsp90 chaperone complex in yeast, mammals, and plants. Thus, in Arabidopsis, CyP40 is specifically required for the vegetative but not the reproductive maturation of the shoot.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berardini, T Z -- Bollman, K -- Sun, H -- Poethig, R S -- R01-GM1893-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2001 Mar 23;291(5512):2405-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Plant Science Institute, Department of Biology, University of Pennsylvania, Philadelphia, PA 19104-6018, USA. spoethig@sas.upenn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11264535" target="_blank"〉PubMed〈/a〉

    A membrane receptor for retinol binding protein mediates cellular uptake of vitamin A (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-01-27
    Description: Vitamin A has diverse biological functions. It is transported in the blood as a complex with retinol binding protein (RBP), but the molecular mechanism by which vitamin A is absorbed by cells from the vitamin A-RBP complex is not clearly understood. We identified in bovine retinal pigment epithelium cells STRA6, a multitransmembrane domain protein, as a specific membrane receptor for RBP. STRA6 binds to RBP with high affinity and has robust vitamin A uptake activity from the vitamin A-RBP complex. It is widely expressed in embryonic development and in adult organ systems. The RBP receptor represents a major physiological mediator of cellular vitamin A uptake.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kawaguchi, Riki -- Yu, Jiamei -- Honda, Jane -- Hu, Jane -- Whitelegge, Julian -- Ping, Peipei -- Wiita, Patrick -- Bok, Dean -- Sun, Hui -- 5T32EY07026/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2007 Feb 9;315(5813):820-5.

    KCNQ1 gain-of-function mutation in familial atrial fibrillation (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-01-11
    Description: Atrial fibrillation (AF) is a common cardiac arrhythmia whose molecular etiology is poorly understood. We studied a family with hereditary persistent AF and identified the causative mutation (S140G) in the KCNQ1 (KvLQT1) gene on chromosome 11p15.5. The KCNQ1 gene encodes the pore-forming alpha subunit of the cardiac I(Ks) channel (KCNQ1/KCNE1), the KCNQ1/KCNE2 and the KCNQ1/KCNE3 potassium channels. Functional analysis of the S140G mutant revealed a gain-of-function effect on the KCNQ1/KCNE1 and the KCNQ1/KCNE2 currents, which contrasts with the dominant negative or loss-of-function effects of the KCNQ1 mutations previously identified in patients with long QT syndrome. Thus, the S140G mutation is likely to initiate and maintain AF by reducing action potential duration and effective refractory period in atrial myocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Yi-Han -- Xu, Shi-Jie -- Bendahhou, Said -- Wang, Xiao-Liang -- Wang, Ying -- Xu, Wen-Yuan -- Jin, Hong-Wei -- Sun, Hao -- Su, Xiao-Yan -- Zhuang, Qi-Nan -- Yang, Yi-Qing -- Li, Yue-Bin -- Liu, Yi -- Xu, Hong-Ju -- Li, Xiao-Fei -- Ma, Ning -- Mou, Chun-Ping -- Chen, Zhu -- Barhanin, Jacques -- Huang, Wei -- New York, N.Y. -- Science. 2003 Jan 10;299(5604):251-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cardiology, Tongji Hospital, and Institute of Medical Genetics, Tongji University, 399 Xin Cun Road, Shanghai 200065, People's Republic of China. drchen@public7.sta.net.cn〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12522251" target="_blank"〉PubMed〈/a〉

    Inhibition of Ras-induced DNA synthesis by expression of the phosphatase MKP-1 (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-10-14
    Description: Mitogen-activated protein kinases (MAP kinases) are common components of signaling pathways induced by diverse growth stimuli. Although the guanidine nucleotide-binding Ras proteins are known to be upstream activators of MAP kinases, the extent to which MAP kinases directly contribute to the mitogenic effect of Ras is as yet undefined. In this study, inhibition of MAP kinases by the MAP kinase phosphatase MKP-1 blocked the induction of DNA synthesis in quiescent rat embryonic fibroblast REF-52 cells by an activated mutant of Ras, V12Ras. These results suggest an essential role for activation of MAP kinases in the transition from the quiescent to the DNA replication phase of the eukaryotic cell cycle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sun, H -- Tonks, N K -- Bar-Sagi, D -- CA53840/CA/NCI NIH HHS/ -- CA55360/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Oct 14;266(5183):285-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cold Spring Harbor Laboratory, NY 11724-2208.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7939666" target="_blank"〉PubMed〈/a〉

    A variant of the HTRA1 gene increases susceptibility to age-related macular degeneration (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-10-21
    Description: Age-related macular degeneration (AMD) is the most common cause of irreversible vision loss in the developed world and has a strong genetic predisposition. A locus at human chromosome 10q26 affects the risk of AMD, but the precise gene(s) have not been identified. We genotyped 581 AMD cases and 309 normal controls in a Caucasian cohort in Utah. We demonstrate that a single-nucleotide polymorphism, rs11200638, in the promoter region of HTRA1 is the most likely causal variant for AMD at 10q26 and is estimated to confer a population attributable risk of 49.3%. The HTRA1 gene encodes a secreted serine protease. Preliminary analysis of lymphocytes and retinal pigment epithelium from four AMD patients revealed that the risk allele was associated with elevated expression levels of HTRA1 mRNA and protein. We also found that drusen in the eyes of AMD patients were strongly immunolabeled with HTRA1 antibody. Together, these findings support a key role for HTRA1 in AMD susceptibility and identify a potential new pathway for AMD pathogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang, Zhenglin -- Camp, Nicola J -- Sun, Hui -- Tong, Zongzhong -- Gibbs, Daniel -- Cameron, D Joshua -- Chen, Haoyu -- Zhao, Yu -- Pearson, Erik -- Li, Xi -- Chien, Jeremy -- Dewan, Andrew -- Harmon, Jennifer -- Bernstein, Paul S -- Shridhar, Viji -- Zabriskie, Norman A -- Hoh, Josephine -- Howes, Kimberly -- Zhang, Kang -- CA98364/CA/NCI NIH HHS/ -- GCRC M01-RR00064/RR/NCRR NIH HHS/ -- P30EY014800/EY/NEI NIH HHS/ -- R01EY14428/EY/NEI NIH HHS/ -- R01EY14448/EY/NEI NIH HHS/ -- R01EY15771/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2006 Nov 10;314(5801):992-3.

    DNA sequence of a gene encoding a BALB/c mouse Ld transplantation antigen (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-02-05
    Description: The sequence of a gene, denoted 27.5, encoding a transplantation antigen for the BALB/c mouse has been determined. Gene transfer studies and comparison of the translated sequence with the partial amino acid sequence of the Ld transplantation antigen establish that gene 27.5 encodes an Ld polypeptide. A comparison of the gene 27.5 sequence with several complementary DNA sequences suggests that the BALB/c mouse may contain a number of closely related L-like genes. Gene 27.5 has eight exons that correlate with the structural domains of the transplantation antigen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moore, K W -- Sher, B T -- Sun, Y H -- Eakle, K A -- Hood, L -- 1 T32 GM07616/GM/NIGMS NIH HHS/ -- GM 06965/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1982 Feb 5;215(4533):679-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7058332" target="_blank"〉PubMed〈/a〉
