中文摘要：

Nogo—B是网状蛋白家族4的重要成员，其广泛表达于中枢神经系统及外周组织，其亚细胞定位于细胞内质网及细胞膜。研究显示，Nogo—B主要参与血管损伤、组织修复、再生及炎症过程的调控，并可能在肿瘤细胞凋亡及中枢神经系统疾病中也发挥重要作用。对Nogo—B的结构及其功能的进一步探索，有助于更加深入地了解其在各种疾病中发挥作用的机制。

英文摘要：

Nogo-B is a major family member of the reticulon protein family 4. It is widely expressed in the central nervous system and peripheral tissues, and is mainly located in endoplasmic reticulum and cell membrane. Previous studies have revealed that Nogo-B plays a key role in vascular injury, tissue repair and inflammation process. It also may be critical for apoptosis of tumor cells and central diseases. Further investigation of the molecular characteristics and biological function of Nogo-B might be of great help to un- derstand its role in diverse diseases.
