胰岛素受体结构及信号转导机制探讨

A Discussion about the Structure of the Insulin Receptor and the Mechanism of the Message Transferred

受体是细胞膜或细胞内能识别生物活性分子,并与之持异性地结合,从而引起特征性生物效应的一类生物大分子.近年来利用基因工程的方法,确定了胰岛素受体(IR)的结构,并对信号转导机制进行了研究,使受体的结构和功能的研究成为可能.

Receptor is a biomacromolecule which exist in the cell membrance oor cytoplasm. It can recognize the living molecule and combine with it particularly, thus respon-dence occured. In recent years using the way of genetic engineering, the structure of the Insulin recepor has been determined and the mechanism of the measage transferred is being researched. That it is possible to reseach the structure and function of Receptor.
