A database search for mammalian prion proteins yielded 23 different sequences for the fragment 124\u2013226, which display a high degree of sequence identity and show relevant amino acid substitutions in only 18 of the 103 positions. Except for a unique isolated negative surface charge in the bovine protein, the amino acid differences are clustered in three distinct regions of the three-dimensional structure of the cellular form of the prion protein. Two of these regions represent potential species-dependent surface recognition sites for protein\u2013protein interactions, which have independently been implicated from\n                    <jats:italic>in vitro<\/jats:italic>\n                    and\n                    <jats:italic>in vivo<\/jats:italic>\n                    studies of prion protein transformation. The third region consists of a cluster of interior hydrophobic side chains that may affect prion protein transformation at later stages, after initial conformational changes in the cellular protein.\n                  <\/jats:p>","DOI":"10.1073\/pnas.94.14.7281","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T10:31:44Z","timestamp":1027679504000},"page":"7281-7285","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":117,"title":["Prion protein NMR structure and species barrier for prion\u2009diseases"],"prefix":"10.1073","volume":"94","author":[{"given":"Martin","family":"Billeter","sequence":"first","affiliation":[{"name":"Institut f\u00fcr Molekularbiologie und Biophysik, Eidgen\u00f6ssische Technische Hochschule, CH-8093 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roland","family":"Riek","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Molekularbiologie und Biophysik, Eidgen\u00f6ssische Technische Hochschule, CH-8093 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerhard","family":"Wider","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Molekularbiologie und Biophysik, Eidgen\u00f6ssische Technische Hochschule, CH-8093 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simone","family":"Hornemann","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Molekularbiologie und Biophysik, Eidgen\u00f6ssische Technische Hochschule, CH-8093 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rudi","family":"Glockshuber","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Molekularbiologie und Biophysik, Eidgen\u00f6ssische Technische Hochschule, CH-8093 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kurt","family":"W\u00fcthrich","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Molekularbiologie und Biophysik, Eidgen\u00f6ssische Technische Hochschule, CH-8093 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[1997,7,8]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.6801762"},{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1675487"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/2151043a0"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0968-0004(96)10063-3"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0014-5793(96)00610-2"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1038\/383685a0"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0960-9822(02)70708-2"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.92.9.3923"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1038\/382180a0"},{"key":"e_1_3_4_10_2","doi-asserted-by":"publisher","DOI":"10.1006\/jmbi.1994.0030"},{"key":"e_1_3_4_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/pro.5560021104"},{"key":"e_1_3_4_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/0092-8674(95)90236-8"},{"key":"e_1_3_4_13_2","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/24.1.21"},{"key":"e_1_3_4_14_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-96519-7"},{"key":"e_1_3_4_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/0263-7855(96)00009-4"},{"key":"e_1_3_4_16_2","doi-asserted-by":"publisher","DOI":"10.1128\/jvi.69.12.7754-7758.1995"},{"key":"e_1_3_4_17_2","doi-asserted-by":"publisher","DOI":"10.1006\/jmbi.1996.0487"}],"container-title":["Proceedings of the National Academy of Sciences"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/pnas.org\/doi\/pdf\/10.1073\/pnas.94.14.7281","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,6,6]],"date-time":"2022-06-06T17:25:23Z","timestamp":1654536323000},"score":1,"resource":{"primary":{"URL":"https:\/\/pnas.org\/doi\/full\/10.1073\/pnas.94.14.7281"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1997,7,8]]},"references-count":17,"journal-issue":{"issue":"14","published-print":{"date-parts":[[1997,7,8]]}},"alternative-id":["10.1073\/pnas.94.14.7281"],"URL":"https:\/\/doi.org\/10.1073\/pnas.94.14.7281","relation":{},"ISSN":["0027-8424","1091-6490"],"issn-type":[{"value":"0027-8424","type":"print"},{"value":"1091-6490","type":"electronic"}],"subject":[],"published":{"date-parts":[[1997,7,8]]},"assertion":[{"value":"1997-05-08","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"1997-07-08","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
