The biochemical properties of various segments of PTB were analysed in order to understand the molecular basis of the PTB functions. The protein exists in oligomeric as well as monomeric form. The central part of PTB (amino acids 169\u2013293) plays a major role in the oligomerization. PTB contains several RNA-binding motifs. Among them, the C-terminal part of PTB (amino acids 329\u2013530) exhibited the strongest RNA-binding activity. The N-terminal part of PTB is responsible for the enhancement of RNA binding by HeLa cell cytoplasmic factor(s).<\/jats:p>","DOI":"10.1042\/bj3310169","type":"journal-article","created":{"date-parts":[[2015,8,10]],"date-time":"2015-08-10T22:01:27Z","timestamp":1439244087000},"page":"169-175","update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":71,"title":["Determination of functional domains in polypyrimidine-tract-binding protein"],"prefix":"10.1042","volume":"331","author":[{"given":"Young L.","family":"OH","sequence":"first","affiliation":[{"name":"Department of Life Science, Pohang University of Science and Technology, San31, Hyoja-Dong, Pohang, Kyungbuk 790-784, South Korea"}]},{"given":"Bumsuk","family":"HAHM","sequence":"additional","affiliation":[{"name":"Department of Life Science, Pohang University of Science and Technology, San31, Hyoja-Dong, Pohang, Kyungbuk 790-784, South Korea"}]},{"given":"Yoon K.","family":"KIM","sequence":"additional","affiliation":[{"name":"Department of Life Science, Pohang University of Science and Technology, San31, Hyoja-Dong, Pohang, Kyungbuk 790-784, South Korea"}]},{"given":"Hae K.","family":"LEE","sequence":"additional","affiliation":[{"name":"Department of Life Science, Pohang University of Science and Technology, San31, Hyoja-Dong, Pohang, Kyungbuk 790-784, South Korea"}]},{"given":"Joo W.","family":"LEE","sequence":"additional","affiliation":[{"name":"Department of Life Science, Pohang University of Science and Technology, San31, Hyoja-Dong, Pohang, Kyungbuk 790-784, South Korea"}]},{"given":"Ok.-K.","family":"SONG","sequence":"additional","affiliation":[{"name":"Department of Life Science, Pohang University of Science and Technology, San31, Hyoja-Dong, Pohang, Kyungbuk 790-784, South Korea"}]},{"given":"Kyoko","family":"TSUKIYAMA-KOHARA","sequence":"additional","affiliation":[{"name":"The Tokyo Metropolitan Institute of Medical Science, Honkomagome, Bunkyo-ku, Tokyo 113, Japan"}]},{"given":"Michinori","family":"KOHARA","sequence":"additional","affiliation":[{"name":"The Tokyo Metropolitan Institute of Medical Science, Honkomagome, Bunkyo-ku, Tokyo 113, Japan"}]},{"given":"Akio","family":"NOMOTO","sequence":"additional","affiliation":[{"name":"The Tokyo Metropolitan Institute of Medical Science, Honkomagome, Bunkyo-ku, Tokyo 113, Japan"}]},{"given":"Sung K.","family":"JANG","sequence":"additional","affiliation":[{"name":"Department of Life Science, Pohang University of Science and Technology, San31, Hyoja-Dong, Pohang, Kyungbuk 790-784, South Korea"}]}],"member":"288","container-title":["Biochemical Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/portlandpress.com\/biochemj\/article-pdf\/331\/1\/169\/630886\/bj3310169.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/portlandpress.com\/biochemj\/article-pdf\/331\/1\/169\/630886\/bj3310169.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,11,24]],"date-time":"2021-11-24T00:41:23Z","timestamp":1637714483000},"score":1,"resource":{"primary":{"URL":"https:\/\/portlandpress.com\/biochemj\/article\/331\/1\/169\/34485\/Determination-of-functional-domains-in"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1998,4,1]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1998,4,1]]}},"URL":"https:\/\/doi.org\/10.1042\/bj3310169","relation":{},"ISSN":["0264-6021","1470-8728"],"issn-type":[{"value":"0264-6021","type":"print"},{"value":"1470-8728","type":"electronic"}],"subject":[],"published":{"date-parts":[[1998,4,1]]}}}
