title: The gene for the microsomal glutathione S-transferase is on human chromosome 12.
abstract: The microsomal glutathione S-transferase (GST) is a unique membrane-bound GST structurally distinct from the cytosolic GSTs. A cDNA encoding this 154 amino acid protein has recently been isolated and characterized. Using the cDNA as the hybridization probe, we now report the assignment of the human microsomal GST gene to chromosome 12 through the use of a panel of mouse-human somatic cell hybrid lines. This locus has recently been designated as GST 12. In addition, genomic Southern blotting data suggest that the human microsomal GST is encoded by a single- or very-low-copy gene. Therefore, the human GST gene superfamily resides on at least four separate chromosomes: 1 (GST 1), 6 (GST 2), 11 (GST 3), and 12 (GST 12).
