Testis cytosol is shown to contain the Yb2Yb2 -homodimer glutathione S-transferase D in addition to the previously described glutathione S-transferases A ( Yb1Yb1 ) and C ( Yb1Yb2 ). Treatment of rats with phenobarbital induces the level of glutathione S-transferase D in testis with no increase in the activities of glutathione S-transferases A and C. This result indicates a specific induction of the Yb2 subunit in testis, in contrast with the situation in rat liver, where phenobarbital specifically induces the Yb1 subunit.
睾丸胞质溶胶中除了先前描述的谷胱甘肽S-转移酶A(Yb1Yb1)和C(Yb1Yb2)外,还含有Yb2Yb2-同型二聚体谷胱甘肽S-转移酶D。用苯巴比妥处理大鼠可诱导睾丸中谷胱甘肽S-转移酶D的水平升高,而谷胱甘肽S-转移酶A和C的活性没有增加。这一结果表明睾丸中Yb2亚基有特异性诱导,这与大鼠肝脏的情况相反,在大鼠肝脏中苯巴比妥特异性诱导Yb1亚基。
