Summaries for GSTK1 Gene

Entrez Gene Summary for GSTK1 Gene

  • This gene encodes a member of the kappa class of the glutathione transferase superfamily of enzymes that function in cellular detoxification. The encoded protein is localized to the peroxisome and catalyzes the conjugation of glutathione to a wide range of hydrophobic substates facilitating the removal of these compounds from cells. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Jan 2009]

GeneCards Summary for GSTK1 Gene

GSTK1 (Glutathione S-Transferase Kappa 1) is a Protein Coding gene. Among its related pathways are Phase II conjugation and Glutathione metabolism. GO annotations related to this gene include receptor binding and glutathione transferase activity.
