Glutathione S-transferase Mu 1 (GSTM1)

Target
GSTM1
Molecular classification
Enzyme, Glutathione S-transferase, Phase II Detoxification Enzyme
01

Overview

Glutathione S-transferase Mu 1 (GSTM1) is a member of the glutathione S-transferase (GST) superfamily, specifically belonging to the mu class. GSTs are phase II detoxification enzymes that catalyze the conjugation of reduced glutathione to a wide variety of electrophilic and hydrophobic compounds, facilitating their detoxification and excretion. Genetic variations, particularly null mutations, significantly impact individual susceptibility to toxins and disease.
