For most genes, the majority of mRNA molecules were associated with ribosomes and presumably engaged in translation. This systematic approach enabled us to recognize genes with unusual behavior. For 43 genes, most mRNA molecules were not associated with ribosomes, suggesting that they may be translationally controlled. For 53 genes, including\n                    <jats:italic>GCN4<\/jats:italic>\n                    ,\n                    <jats:italic>CPA1<\/jats:italic>\n                    , and\n                    <jats:italic>ICY2<\/jats:italic>\n                    , three genes for which translational control is known to play a key role in regulation, most mRNA molecules were associated with a single ribosome. The number of ribosomes associated with mRNAs increased with increasing length of the putative protein-coding sequence, consistent with longer transit times for ribosomes translating longer coding sequences. The density at which ribosomes were distributed on each mRNA (i.e., the number of ribosomes per unit ORF length) was well below the maximum packing density for nearly all mRNAs, consistent with initiation as the rate-limiting step in translation. Global analysis revealed an unexpected correlation: Ribosome density decreases with increasing ORF length. Models to account for this surprising observation are discussed.\n                  <\/jats:p>","DOI":"10.1073\/pnas.0635171100","type":"journal-article","created":{"date-parts":[[2003,4,1]],"date-time":"2003-04-01T14:25:08Z","timestamp":1049207108000},"page":"3889-3894","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":623,"title":["Genome-wide analysis of mRNA translation profiles in\n                    <i>Saccharomyces<\/i>\n                    <i>cerevisiae<\/i>"],"prefix":"10.1073","volume":"100","author":[{"given":"Yoav","family":"Arava","sequence":"first","affiliation":[{"name":"Department of Biochemistry, Stanford University, Stanford, CA 94305-5307; The Howard Hughes Medical Institute, Stanford, CA 94305-5428; and Department of Statistics, Stanford University, Stanford, CA 94305-4065"}]},{"given":"Yulei","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Stanford University, Stanford, CA 94305-5307; The Howard Hughes Medical Institute, Stanford, CA 94305-5428; and Department of Statistics, Stanford University, Stanford, CA 94305-4065"}]},{"given":"John D.","family":"Storey","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Stanford University, Stanford, CA 94305-5307; The Howard Hughes Medical Institute, Stanford, CA 94305-5428; and Department of Statistics, Stanford University, Stanford, CA 94305-4065"}]},{"given":"Chih Long","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Stanford University, Stanford, CA 94305-5307; The Howard Hughes Medical Institute, Stanford, CA 94305-5428; and Department of Statistics, Stanford University, Stanford, CA 94305-4065"}]},{"given":"Patrick O.","family":"Brown","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Stanford University, Stanford, CA 94305-5307; The Howard Hughes Medical Institute, Stanford, CA 94305-5428; and Department of Statistics, Stanford University, Stanford, CA 94305-4065"}]},{"given":"Daniel","family":"Herschlag","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Stanford University, Stanford, CA 94305-5307; The Howard Hughes Medical Institute, Stanford, CA 94305-5428; and Department of Statistics, Stanford University, Stanford, CA 94305-4065"}]}],"member":"341","published-online":{"date-parts":[[2003,3,26]]},"reference":[{"key":"e_1_3_2_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0092-8674(00)00015-5"},{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1091\/mbc.9.12.3273"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0092-8674(00)81641-4"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.278.5338.680"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.285.5429.901"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1038\/4462"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0092-8674(00)81845-0"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1069415"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.092538799"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1038\/75603"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1093\/embo-reports\/kvf025"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.97.26.14085"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.96.23.13118"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.96.19.10632"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1128\/MCB.21.3.916-927.2001"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1096\/fj.99-0852com"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0092-8674(01)00568-2"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.274.5287.546"},{"key":"e_1_3_2_19_2","first-page":"33","volume-title":"Translational Control of Gene Expression","author":"Hershey J W B","year":"2000","unstructured":"J W B Hershey, W C Merrick Translational Control of Gene Expression, eds N Sonenberg, J W B Hershey, M B Mathews (Cold Spring Harbor Lab.
