Subunits of multiple molecular forms of dimeric glutathioneS-transferase in rat liver cytosol were analyzed by two-dimensional gel electrophoresis (isoelectric focusing/sodium dodecyl sulfate-electrophoresis) followed by staining with Coomassie blue dye. The five subunits, Ya, Yb, Yb′, Yc, and Yp (Mr's 26,500, 27,500, 27,500, 28,500, and 26,000, respectively) of seven molecular forms, A2, AC, C2, B2, BL, L2, and GST-P, were identified by comparison of molecular weights and pIvalues with those of purified molecular forms and by immunoadsorption of the molecular forms in the cytosol as well as those synthesizedin vitrousing antibodies against the seven forms. Yp is the subunit of placental glutathioneS-transferase, GST-P (YpYp), which is markedly increased in carcinogen-treated rat livers [A. Kitaharaet al.(1984)Cancer Res.44, 2698–2703; K. Satohet al.(1985)Proc. Natl. Acad. Sci. USA82, 3964–3968]. Microheterogeneity was detectable within Yb, Yb′, and Yp subunits, the different forms, termed Yb1, Yb2, Yb′1, Yb′2, and Yp1, Yp2, being similar in size but differing by approx. 0.3 pIunit within each subunit. These microheterogeneous forms were also detectable in the polypeptides translatedin vitroin a rabbit reticulocyte lysate translation system from liver poly(A)-containing RNAs, suggesting that they are translatable from distinct mRNAs.
