Vgl mRNA localization signal RNA is also a cis-acting element to suppress translation in xenopus oocytes
碩士 === 國立陽明大學 === 生物藥學研究所 === 84 === mRNA的位移作用是早期胚胎發育時細胞分化的重要機制。在非洲有爪水生蛙卵母細胞中,Vgl mRNA的位移現象是目前被研究最為清楚的系統;Vgl mRNA在卵母細胞生長期間,會由平均分佈的形式漸漸的朝植物極運動並固著在植物極上,由於vgl蛋白質只在植物極表現,這似乎表示Vgl mRNA在位移的過程中,同時受到了轉譯抑制作用,所以不會在植物極以外的部位表現蛋白質。目前,雖然已發覺在卵母細胞中,抑制 maternal mRNA轉譯之masking蛋白質─p56及p54會與Vgl定位訊號RN...
