"Presence of hGSTK1 in both peroxisomes and mitochondria. The C-terminus of hGSTK1 is essential for localization of the protein to peroxisomes and the C-terminal sequence Ala-Arg-Leu represents a peroxisome targeting signal 1 (PTS1); Gene and protein characterization; its subcellular localization in peroxisomes suggesting a new function for this family of enzymes [glutathione S-transferase kappa (hGSTK1)]"xsd:string
