GST's are responsible for the metabolism of a broad range of xenobiotics and carcinogens.
The enzyme catalyzes the reaction of glutathione with a wide variety of organic compounds to form thioethers, a reaction that is sometimes a first step in a detoxification process leading to mercapturic acid formation.
Based on aa sequence similarities and antibody cross-reactivities, the mammalian cytosolic GSTs are divided into the following classes: alpha, mu, kappa, theta, pi, zeta, omega and sigma.
GSTs exists as homodimers of ~25kD.
GST A1-1 is mainly found in kidney, intestine, lung, and liver.
GST M1-1 is restricted to liver and few other tissues.
GST P1-1 has a widespread distribution in most tumor cells and tissues but it is absent in liver.
The GST M1-1 is the type b allelic variant and corresponds to human GST Y.
GSTA1: The alpha gene cluster consists of 5 genes GSTA1-GSTA5; the GSTA1 contains 222aa (chr 6p12), widely expressed in human tissues of liver, kidney, testis, adrenal and pancrease.
GST alpha 1- 1 concentration as a marker for hepatocellular impairment, GSTA1 concentration in blood is a more specific marker than AST or ALT, and has a shorter half-life than ALT The GSTA1 shows enzyme activity towards CDNR; NBD-CI; delta 5 AD, PGE2 AND PGF2a synthase.
