Cytosolic and membrane-bound forms of glutathione S-transferase are encoded by two distinct supergene families. At present, eight distinct classes of the soluble cytoplasmic mammalian glutathione S-transferases have been identified: alpha, kappa, mu, omega, pi, sigma, theta and zeta. This gene encodes a glutathione S-transferase that belongs to the mu class. The mu class of enzymes functions in the detoxification of electrophilic compounds, including carcinogens, therapeutic drugs, environmental toxins and products of oxidative stress, by conjugation with glutathione. The genes encoding the mu class of enzymes are organized in a gene cluster on chromosome 1p13.3 and are known to be highly polymorphic. These genetic variations can change an individual's susceptibility to carcinogens and toxins as well as affect the toxicity and efficacy of certain drugs. Diversification of these genes has occurred in regions encoding substrate-binding domains, as well as in tissue expression patterns, to accommodate an increasing number of foreign compounds.

[中文简述(自动翻译):]  胞浆和谷胱甘肽S-转移酶的膜结合形式是通过两个不同的表生家族编码。目前,可溶性胞质哺乳动物谷胱甘肽S-转移酶的八个不同类别已经确定:α,KAPPA,亩,欧米茄,PI,西格玛,theta和泽塔。这个基因编码谷胱甘肽S-转移酶属于该亩类。穆类的酶的功能在电子化合物,其中包括致癌物质,治疗药物,环境毒素和氧化应激的产品,通过与谷胱甘肽结合的解毒作用。编码亩类酶的基因在上1p13.3染色体基因簇组织并已知是高度多态性。这些遗传变异可改变个体的易感性致癌物和毒素以及影响某些药物的毒性和疗效。这些基因的多样化已发生区域编码底物结合结构域,以及在组织中的表达模式,以容纳外来化合物的越来越多。 [由RefSeq的,2008年7月提供]
