摘要
锌是动物必需的微量元素之一，具有广泛的生理功能。金属硫蛋白是一类低分子量，富含半胱氨酸，与金属元素具有高度亲和力且能被其诱导的功能特异的蛋白质。本文对金属硫蛋白的生物学功能及锌与之基因表达的关系进行了阐述。
Zinc is an essential trace element for animal which has extensive physiological functions. Metallothionein is a kind of specific protein which has low molecular weight and is rich in cysteine. It has high affinity for metallic elements, and can be induced by them. This article reviews biological functions of metallothionein and describes the relationship between zinc and metallothionein gene expression.
