CD44 (a cell surface receptor) and two hyaluronidases (HYAL1 and HYAL2) are thought to be responsible for HA binding and degradation; however, the role of these molecules in HA catabolism remains controversial. Here we show that KIAA1199, a deafness gene of unknown function, plays a central role in HA binding and depolymerization that is independent of CD44 and HYAL enzymes. The specific binding of KIAA1199 to HA was demonstrated in glycosaminoglycan-binding assays. We found that knockdown of KIAA1199 abolished HA degradation by human skin fibroblasts and that transfection of KIAA1199 cDNA into cells conferred the ability to catabolize HA in an endo-\u03b2-\n                    <jats:italic>N<\/jats:italic>\n                    -acetylglucosaminidase\u2013dependent manner via the clathrin-coated pit pathway. Enhanced degradation of HA in synovial fibroblasts from patients with osteoarthritis or rheumatoid arthritis was correlated with increased levels of KIAA1199 expression and was abrogated by knockdown of KIAA1199. The level of KIAA1199 expression in uninflamed synovium was less than in osteoarthritic or rheumatoid synovium. These data suggest that KIAA1199 is a unique hyaladherin with a key role in HA catabolism in the dermis of the skin and arthritic synovium.\n                  <\/jats:p>","DOI":"10.1073\/pnas.1215432110","type":"journal-article","created":{"date-parts":[[2013,3,19]],"date-time":"2013-03-19T03:06:17Z","timestamp":1363662377000},"page":"5612-5617","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":257,"title":["KIAA1199, a deafness gene of unknown function, is a new hyaluronan binding protein involved in hyaluronan depolymerization"],"prefix":"10.1073","volume":"110","author":[{"given":"Hiroyuki","family":"Yoshida","sequence":"first","affiliation":[{"name":"Innovative Beauty Science Laboratory, Kanebo Cosmetics, Inc., Kotobuki-cho, Odawara-shi, Kanagawa 250-0002, Japan;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aya","family":"Nagaoka","sequence":"additional","affiliation":[{"name":"Innovative Beauty Science Laboratory, Kanebo Cosmetics, Inc., Kotobuki-cho, Odawara-shi, Kanagawa 250-0002, Japan;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayumi","family":"Kusaka-Kikushima","sequence":"additional","affiliation":[{"name":"Innovative Beauty Science Laboratory, Kanebo Cosmetics, Inc., Kotobuki-cho, Odawara-shi, Kanagawa 250-0002, Japan;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megumi","family":"Tobiishi","sequence":"additional","affiliation":[{"name":"Innovative Beauty Science Laboratory, Kanebo Cosmetics, Inc., Kotobuki-cho, Odawara-shi, Kanagawa 250-0002, Japan;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keigo","family":"Kawabata","sequence":"additional","affiliation":[{"name":"Innovative Beauty Science Laboratory, Kanebo Cosmetics, Inc., Kotobuki-cho, Odawara-shi, Kanagawa 250-0002, Japan;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsuya","family":"Sayo","sequence":"additional","affiliation":[{"name":"Innovative Beauty Science Laboratory, Kanebo Cosmetics, Inc., Kotobuki-cho, Odawara-shi, Kanagawa 250-0002, Japan;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shingo","family":"Sakai","sequence":"additional","affiliation":[{"name":"Innovative Beauty Science Laboratory, Kanebo Cosmetics, Inc., Kotobuki-cho, Odawara-shi, Kanagawa 250-0002, Japan;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshinori","family":"Sugiyama","sequence":"additional","affiliation":[{"name":"Innovative Beauty Science Laboratory, Kanebo Cosmetics, Inc., Kotobuki-cho, Odawara-shi, Kanagawa 250-0002, Japan;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroyuki","family":"Enomoto","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, School of Medicine, Keio University, Shinjuku-ku, Tokyo 160-0016, Japan; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasunori","family":"Okada","sequence":"additional","affiliation":[{"name":"Department of Pathology, School of Medicine, Keio University, Shinjuku-ku, Tokyo 160-0016, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shintaro","family":"Inoue","sequence":"additional","affiliation":[{"name":"Innovative Beauty Science Laboratory, Kanebo Cosmetics, Inc., Kotobuki-cho, Odawara-shi, Kanagawa 250-0002, Japan;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2013,3,18]]},"reference":[{"key":"e_1_3_3_1_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2796.1997.00170.x"},{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M800886200"},{"key":"e_1_3_3_3_2","first-page":"75","article-title":"The role of hyaluronic acid (hyaluronan) in health and disease: Interactions with cells, cartilage and components of synovial fluid","volume":"12","author":"Ghosh P","year":"1994","unstructured":"P Ghosh, The role of hyaluronic acid (hyaluronan) in health and disease: Interactions with cells, cartilage and components of synovial fluid.
