NEU1としても知られるシアリダーゼ1（リソソームシアリダーゼ）ノイラミニダーゼ1 (ノイラミニダーゼワン、Neuraminidase 1、EC3.2.1.18）は、シアル酸残基と他の分子とのグリコシド結合を加水分解するエキソグリコシダーゼである。哺乳類細胞のリソソーム内にカテプシンAと複合体を形成して存在する。

哺乳類のリソソームノイラミニダーゼ酵素であり、ヒトではNEU1遺伝子によってコードされている ^[5] ^[6]。

概要

動物細胞のリソソーム内にて、糖タンパク質や糖脂質から末端シアル酸残基を加水分解により除去するエキソグリコシダーゼである。ヒトノイラミニダーゼ1は他のノイラミニダーゼ(NEU2、NEU3、NEU4)とは異なり、単独では活性がない。ヒトノイラミニダーゼ1は、他のノイラミニダーゼアイソザイムとは異なり、アスパラギン結合型糖鎖をもつ^[7]。哺乳類の培養細胞にCMVプロモーターなどの強力なプロモーターで過剰発現させると細胞内で結晶化する^[8]。

相互作用

カテプシンAと相互作用する。ノイラミニダーゼ1は単独では活性がなく、カテプシンAと会合することで活性化される。また、粗面小胞体内腔で生合成されるが、単独ではリソソームへあまり輸送されず、カテプシンAとの会合により輸送が促進される^[14]。
