Title: ウロコルチンｉｉｉ及びその利用
IPC: A61P1/00
Filed: 2002-03-15
Abstract: 公開されたヒトゲノム・データベースの検索によって、フグ・ウロコルチンとかなりの配列相同性を有するヒトＥＴＳ、遺伝子バンク登録番号ＡＷ２９３２４９が同定された。ヒトゲノムＤＮＡから全長配列が増幅され、配列決定された。新しい配列と、ヒト・ウロコルチンＩ及びヒト・ウロコルチンＩＩとの配列相同性比較は、この配列がウロコルチンＩＩＩ（ＵｃｎＩＩＩ）と命名された新しいヒト・ウロコルチンをコードすることを明らかにした。一方、ウロコルチンＩＩＩはＣＲＦ−Ｒ１又はＣＲＦ−Ｒ２に対して高い親和性を有していないが、ＣＲＦ−Ｒ２に対する親和性はＣＲＦ−Ｒ１に対するより大きい。ウロコルチンＩＩＩはＣＲＦ−Ｒ２α又はβを発現する細胞内で環式ＡＭＰ生成を促進させる。このように、その親和性が十分高いので、ウロコルチンＩＩＩはＣＲＦ−Ｒ２の天然作用物質として作用する。しかしながら、またウロコルチンＩＩＩが今後同定されるべきレセプタのより強力な作用物質である可能性もある。
