Glutathione S-transferase omega-2 is an enzyme that in humans is encoded by the GSTO2 gene.^[1][2]

Model organisms

Model organisms have been used in the study of GSTO2 function. A conditional knockout mouse line called Gsto2^{tm2a(KOMP)Wtsi} was generated at the Wellcome Trust Sanger Institute.^[3] Male and female animals underwent a standardized phenotypic screen^[4] to determine the effects of deletion.^[5][6][7][8] Additional screens performed: - In-depth immunological phenotyping^[9]
