Strain description | Dnmt3b遺伝子のノックアウトマウス。Dnmt3b遺伝子座の酵素活性に必須なモチーフをコードする領域を欠損しており、Dnmt3b完全欠損変異と考えられる。哺乳類は、互いに高いアミノ酸配列類似性のある二つのDe novo型DNAメチル化酵素Dnmt3a、Dnmt3bを持つ。両者は異なるアイソフォーム、発現パターンを示し、互いに重複する機能とそれぞれに特異的な機能を持つ。ホモノックアウトマウスは、ホモマウスは胎生14.5-16.5日で致死となる、形態的異常はみとめられないものの、胚全体に浮腫、異所的出血、胎仔肝形成不全、心室隔壁異常を呈する。動原体近傍反復配列におけるDNAメチル化低下が認められる。ホモ胚から作成した胚繊維が細胞 (MEFs) は増殖能低下、細胞老化、染色体異常を起こす。Agouti遺伝子座に連鎖している。Dnmt3aノックアウトマウス (RBRC03730) 、Dnmt3a floxedマウス (RBRC03731) 、Dnmt3b floxedマウス (RBRC03733) 。 |
