セクエストソーム-1(Sequestosome 1)は、ヒトではSQSTM1遺伝子がコードするタンパク質である。ユビキチン結合タンパク質p62とも呼ばれ、選択的オートファジーのために標的となる他のタンパク質と結合するオートファゴソームのカーゴタンパク質である。GATA4（英語版）と結合してこれを分解の標的とすると、GATA-4に関連する老化や細胞老化随伴分泌現象（英語版）を阻害することができる。

モデル生物

SQSTM1遺伝子の機能の研究のためにモデル生物が用いられている。ハイスループットの突然変異誘発により病気の動物モデルを作り出し科学者に頒布するプロジェクトである国際ノックアウトマウスコンソーシアム（英語版）がSqstm1^{tm1a(KOMP)Wtsi}と呼ばれるコンディショナルノックアウトマウスの系統を作り出している。

遺伝子欠損の効果を確認するために、規格化された表現型スクリーニングが雄雌の動物に対して行われた。22の試験がホモ接合変異マウスに対して行われ、そのうちの1つで重大な異常が観察された。メスは、赤血球分布幅の増加や平均血小板容積の増加等、全血球計算のパラメータが異常値を示した。

相互作用

セクエストソーム-1は、以下のタンパク質とタンパク質間相互作用する。
