Research Abstract

「ミオシン・スーパーファミリー」の一つであるmyosinVIのヒト血液細胞における発現と局在を種々の阻害剤を用いて解析した。単球・マクロファージ、巨核球及び形質細胞においてmyosinVIはRab8 とcomplex をつくりゴルジ体から細胞膜やリソソームなどの細胞内小器官への輸送の関与が示唆された。MYH9 異常症の遺伝子解析で2つの新規のin-frame欠失変異を発見した。また、3つ目の20-kDa light chain isoform (MLC-2C)を同定した。MLC-2C遺伝子導入によりJurkat 細胞は付着性およびCD3 の発現強度・陽性率が増加した
