    Late Pliocene Homo and hominid land use from Western Olduvai Gorge, Tanzania (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-02-22
    Description: Excavation in the previously little-explored western portion of Olduvai Gorge indicates that hominid land use of the eastern paleobasin extended at least episodically to the west. Finds included a dentally complete Homo maxilla (OH 65) with lower face, Oldowan stone artifacts, and butchery-marked bones dated to be between 1.84 and 1.79 million years old. The hominid shows strong affinities to the KNM ER 1470 cranium from Kenya (Homo rudolfensis), a morphotype previously unrecognized at Olduvai. ER 1470 and OH 65 can be accommodated in the H. habilis holotype, casting doubt on H. rudolfensis as a biologically valid taxon.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blumenschine, Robert J -- Peters, Charles R -- Masao, Fidelis T -- Clarke, Ronald J -- Deino, Alan L -- Hay, Richard L -- Swisher, Carl C -- Stanistreet, Ian G -- Ashley, Gail M -- McHenry, Lindsay J -- Sikes, Nancy E -- Van Der Merwe, Nikolaas J -- Tactikos, Joanne C -- Cushing, Amy E -- Deocampo, Daniel M -- Njau, Jackson K -- Ebert, James I -- New York, N.Y. -- Science. 2003 Feb 21;299(5610):1217-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Human Evolutionary Studies, Department of Anthropology, 131 George Street, Rutgers University, New Brunswick, NJ 08901-1414, USA. rjb@rci.rutgers.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12595689" target="_blank"〉PubMed〈/a〉

    Ubistatins inhibit proteasome-dependent degradation by binding the ubiquitin chain (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-10-02
    Description: To identify previously unknown small molecules that inhibit cell cycle machinery, we performed a chemical genetic screen in Xenopus extracts. One class of inhibitors, termed ubistatins, blocked cell cycle progression by inhibiting cyclin B proteolysis and inhibited degradation of ubiquitinated Sic1 by purified proteasomes. Ubistatins blocked the binding of ubiquitinated substrates to the proteasome by targeting the ubiquitin-ubiquitin interface of Lys(48)-linked chains. The same interface is recognized by ubiquitin-chain receptors of the proteasome, indicating that ubistatins act by disrupting a critical protein-protein interaction in the ubiquitin-proteasome system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Verma, Rati -- Peters, Noel R -- D'Onofrio, Mariapina -- Tochtrop, Gregory P -- Sakamoto, Kathleen M -- Varadan, Ranjani -- Zhang, Mingsheng -- Coffino, Philip -- Fushman, David -- Deshaies, Raymond J -- King, Randall W -- CA78048/CA/NCI NIH HHS/ -- GM068276/GM/NIGMS NIH HHS/ -- GM65334/GM/NIGMS NIH HHS/ -- GM66492/GM/NIGMS NIH HHS/ -- P50 CA92131/CA/NCI NIH HHS/ -- R01 GM-45335/GM/NIGMS NIH HHS/ -- R21CA108545/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2004 Oct 1;306(5693):117-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Howard Hughes Medical Institute (HHMI), California Institute of Technology, Pasadena, CA 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15459393" target="_blank"〉PubMed〈/a〉
