Research Abstract	ヒト疾病に関与する多くの疾患原因遺伝子についは機能解析が進み、疾患の表現型と原因遺伝子の生理機能との関連が明らかにされている。しかし、ゲノム解析や既知の遺伝子との相同性により単離、同定された新規遺伝子の生理機能は未だ不明なものが多い。そこで本研究においては、細胞におけるシグナル伝達や転写調節に関与する近縁遺伝子群の機能を比較、解析することにより、遺伝子情報から機能情報を予測する手法を確立しようと試みた。 1.TGF-βのシグナルを伝達するSmad転写因子群に属するSmad2とSmad3は構造的に高い相同性を有するが、細胞のG1期停止にはSmad2、Smad3が共に関与するが、アポトーシス誘導には主にSmad3が関与し、生理作用が異なることを明らかにした。 2.癌抑制遺伝子p53の類似遺伝子として同定されたp51遺伝子の遺伝子構造、生理機能をp53、p73遺伝子と比較することにより、p51遺伝子にはp53には見られない複数のアイソフォームが存在し、また、四肢、皮膚の分化における独自の機能を有することを見出した。 3.成人T細胞白血病ウイルス(HTLV-l)のTax遺伝子の変異とそのE2F転写因子活性化能を解析し、変異の構造的な意味を明らかにした。 4.軟骨分解活性を有するマトリックスメタロプロテアーゼ(MMP)群を構成するメンバーの生理機能、遺伝子構造を解析し、MMP-3遺伝子の活性化にはMMP-7刺激によりマクロファージから産生されるTNF-αが必須であることが見出された。
