Expression and localization of importin 13 in fetal mouse brain tissues

Abstract

由于真核细胞的基因复制、转录与蛋白质的表达翻译在细胞内分区进行,蛋白质及核酸等生物大分子跨核膜转运成为细胞中最重要的生物学功能之一。Importinβ家族成员是一类真核生物中广泛分布的核质转运受体蛋白。Importin13(Imp13)是这个家族成员之一,也是目前所知的哺乳动物细胞中少数能双向转运底物蛋白的蛋白质之一。目前研究已发现目前研究已发现Imp13的底物有hUbc9,RBM8(也称Y14),Pax3,Pax6,NF-YB/NF-YC,GR,myopodin,negativecofactor2,CHRAC-15/17,p12/CHRAC-17和eIF-1A。这些底物大多与发育有关,因此,...Since DNA replication and protein expression take part in the different compartments of an eukaryotic cell, nucleocytoplasmic trafficking plays an important role in the cell activities. Importin-β family members act as nuclear transport receptor in many nuclear transport activities.Interestingly, impotin13 (Imp13), a member of importin-β family, is found to be one bidirectional transport receptor ...学位:理学博士院系专业:生命科学学院生物学系_细胞生物学学号:2162006015331
