Previous GeneCards Identifiers for GSTA4 Gene
Cytosolic and membrane-bound forms of glutathione S-transferase are encoded by two distinct supergene families. These enzymes are involved in cellular defense against toxic, carcinogenic, and pharmacologically active electrophilic compounds. 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-tranferase belonging to the alpha class. The alpha class genes, which are located in a cluster on chromosome 6, are highly related and encode enzymes with glutathione peroxidase activity that function in the detoxification of lipid peroxidation products. Reactive electrophiles produced by oxidative metabolism have been linked to a number of degenerative diseases including Parkinson's disease, Alzheimer's disease, cataract formation, and atherosclerosis.

GeneCards Summary for GSTA4 Gene
GSTA4 (Glutathione S-Transferase Alpha 4) is a Protein Coding gene. Diseases associated with GSTA4 include Hepatocellular Carcinoma. Among its related pathways are Drug metabolism - cytochrome P450 and Gastric cancer. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and glutathione transferase activity. An important paralog of this gene is GSTA1.
UniProtKB/Swiss-Prot Summary for GSTA4 Gene
Conjugation of reduced glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles. This isozyme has a high catalytic efficiency with 4-hydroxyalkenals such as 4-hydroxynonenal (4-HNE).
