Actions biochimiques/physiologiques
Glutathione S-transferase alpha 4 (GSTA4) is an enzyme that in humans is encoded by the GSTA4 gene. Glutathione S-transferases (GSTs) are a family of enzymes that play an important role in detoxification by catalyzing the conjugation of many hydrophobic and electrophilic compounds with reduced glutathione. Based on their biochemical, immunologic, and structural properties, cytosolic and membrane-bound forms of glutathione S-transferase are encoded by two distinct supergene families. 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. The GSTs are thought to function in xenobiotic metabolism and play a role in susceptibility to cancer, and other diseases.
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.

Conjugation to glutathione (GSH) by glutathione transferase A4-4 (GSTA4-4) is a major route of elimination for the lipid peroxidation product 4-hydroxynonenal (HNE), a toxic compound that contributes to numerous diseases. Both enantiomers of HNE are presumed to be toxic, and

Our recent work in endothelial cells and human atherosclerotic plaque showed that overexpression of glutathione-S-tranferases (GSTs) in endothelium protects against oxidative damage from aldehydes such as 4-HNE. Nuclear factor (NF)-kappaB plays a crucial role during inflammation and immune responses by

Oxidative stress might participate in the carcinogenesis of human esophageal squamous cell carcinomas (hESCC). 4-Hydroxynonenal (HNE) is a major product of membrane lipid peroxidation with short life. It might act as an important mediator through the generation of adducts and

GST Alpha 4 (GSTA4) has an important role in the protection against oxidative stress induced by carcinogens such as tobacco smoke. However, few studies investigated the association between GSTA4 polymorphisms and lung cancer risk. We genotyped three selected GSTA4 SNPs

Mutation research, 579(1-2), 107-114 (2005-08-02)
Several lines of evidence, including an increased level of lipid peroxidation and the depletion of antioxidant molecules like as glutathione (GSH), indicate that oxidative stress plays an important role in the pathogenesis of several neurodegenerative disorders, such as Parkinson's disease
