The nonenzymatic functions of GSTs involve their interactions with cellular proteins, such as, Jun N-terminal kinase,(JNK), tumor necrosis factor receptor-associated factor-2 (TRAF2), apoptosis-signal-regulating kinase 1 (ASK), serine/threonine kinases (PKA, PKC), and tissue transglutaminase 2 (TGM2), during which, either the interacting protein partner undergoes functional alteration or the GST protein itself is post-translationally modified and/or functionally altered [53], [74]
Some people naturally have more melanin, which may lead to stronger pigmentation or uneven tone
