    Description: The anaphase-promoting complex is composed of eight protein subunits, including BimE (APC1), CDC27 (APC3), CDC16 (APC6), and CDC23 (APC8). The remaining four human APC subunits, APC2, APC4, APC5, and APC7, as well as human CDC23, were cloned. APC7 contains multiple copies of the tetratrico peptide repeat, similar to CDC16, CDC23, and CDC27. Whereas APC4 and APC5 share no similarity to proteins of known function, APC2 contains a region that is similar to a sequence in cullins, a family of proteins implicated in the ubiquitination of G1 phase cyclins and cyclin-dependent kinase inhibitors. The APC2 gene is essential in Saccharomyces cerevisiae, and apc2 mutants arrest at metaphase and are defective in the degradation of Pds1p. APC2 and cullins may be distantly related members of a ubiquitin ligase family that targets cell cycle regulators for degradation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yu, H -- Peters, J M -- King, R W -- Page, A M -- Hieter, P -- Kirschner, M W -- CA16519/CA/NCI NIH HHS/ -- GM26875-17/GM/NIGMS NIH HHS/ -- GM39023-08/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1998 Feb 20;279(5354):1219-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Harvard Medical School, 240 Longwood Avenue, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9469815" target="_blank"〉PubMed〈/a〉

    Description: Small molecules that perturb specific protein functions are valuable tools for dissecting complex processes in mammalian cells. A combination of two phenotype-based screens, one based on a specific posttranslational modification, the other visualizing microtubules and chromatin, was used to identify compounds that affect mitosis. One compound, here named monastrol, arrested mammalian cells in mitosis with monopolar spindles. In vitro, monastrol specifically inhibited the motility of the mitotic kinesin Eg5, a motor protein required for spindle bipolarity. All previously known small molecules that specifically affect the mitotic machinery target tubulin. Monastrol will therefore be a particularly useful tool for studying mitotic mechanisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mayer, T U -- Kapoor, T M -- Haggarty, S J -- King, R W -- Schreiber, S L -- Mitchison, T J -- CA78048/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1999 Oct 29;286(5441):971-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, and Institute of Chemistry and Cell Biology, Harvard Medical School, Boston, MA 02115, USA.

    Description: Field observations and satellite geodesy indicate that little crustal shortening has occurred along the central to southern margin of the eastern Tibetan plateau since about 4 million years ago. Instead, central eastern Tibet has been nearly stationary relative to southeastern China, southeastern Tibet has rotated clockwise without major crustal shortening, and the crust along portions of the eastern plateau margin has been extended. Modeling suggests that these phenomena are the result of continental convergence where the lower crust is so weak that upper crustal deformation is decoupled from the motion of the underlying mantle. This model also predicts east-west extension on the high plateau without convective removal of Tibetan lithosphere and without eastward movement of the crust east of the plateau.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Royden -- Burchfiel -- King -- Wang -- Chen -- Shen -- Liu -- New York, N.Y. -- Science. 1997 May 2;276(5313):788-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉L.

    Description: The initiation of anaphase and exit from mitosis require the activation of a proteolytic system that ubiquitinates and degrades cyclin B. The regulated component of this system is a large ubiquitin ligase complex, termed the anaphase-promoting complex (APC) or cyclosome. Purified Xenopus laevis APC was found to be composed of eight major subunits, at least four of which became phosphorylated in mitosis. In addition to CDC27, CDC16, and CDC23, APC contained a homolog of Aspergillus nidulans BIME, a protein essential for anaphase. Because mutation of bimE can bypass the interphase arrest induced by either nimA mutation or unreplicated DNA, it appears that ubiquitination catalyzed by APC may also negatively regulate entry into mitosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peters, J M -- King, R W -- Hoog, C -- Kirschner, M W -- New York, N.Y. -- Science. 1996 Nov 15;274(5290):1199-201.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Harvard Medical School, 240 Longwood Avenue, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8895470" target="_blank"〉PubMed〈/a〉

    Description: Oscillations in the activity of cyclin-dependent kinases (CDKs) promote progression through the eukaryotic cell cycle. This review examines how proteolysis regulates CDK activity-by degrading CDK activators or inhibitors-and also how proteolysis may directly trigger the transition from metaphase to anaphase. Proteolysis during the cell cycle is mediated by two distinct ubiquitin-conjugation pathways. One pathway, requiring CDC34, initiates DNA replication by degrading a CDK inhibitor. The second pathway, involving a large protein complex called the anaphase-promoting complex or cyclosome, initiates chromosome segregation and exit from mitosis by degrading anaphase inhibitors and mitotic cyclins. Proteolysis therefore drives cell cycle progression not only by regulating CDK activity, but by directly influencing chromosome and spindle dynamics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉King, R W -- Deshaies, R J -- Peters, J M -- Kirschner, M W -- New York, N.Y. -- Science. 1996 Dec 6;274(5293):1652-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Harvard Medical School, 240 Longwood Ave., Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8939846" target="_blank"〉PubMed〈/a〉

    Notes: Plants of Poa pratensis cv. Holt initiate inflorescence primordia when exposed to short days (SD) and low temperature, but require a secondary induction by at least 4 long days (LD) for further inflorescence development and stem elongation. Single or double applications of 10 µg per plant of gibberellins A1, A3, A5 and 16,17-dihydro A5 (DHGA5) induced inflorescence development in a high proportion of plants in SD, but only if the plants were detillered to a single stem. Exposure to 2 LD cycles did not cause heading and flowering alone but enhanced the effect of exogenous gibberellins (GAs), bringing flowering to 100%. GA5 and DHGA5 were less effective than GA1 and GA3 in SD, especially with double applications, but were more effective than GA1 and GA3 when given together with 2 LD. The GAs had differential effects on vegetative growth and flowering, GA5 and DHGA5 causing much less leaf and stem growth than the other two GAs. Marginal induction, whether by LD or GA application, resulted in a high proportion of spikelets with viviparous proliferation. Thus, whereas GAs are inhibitory to the primary induction by SD, they can replace secondary induction by LD when vegetative growth is limited.
