Function
GSTO1_HUMAN Exhibits glutathione-dependent thiol transferase and dehydroascorbate reductase activities. Has S-(phenacyl)glutathione reductase activity. Has also glutathione S-transferase activity. Participates in the biotransformation of inorganic arsenic and reduces monomethylarsonic acid (MMA) and dimethylarsonic acid.[1] [2] [3] [4] [5]
Publication Abstract from PubMed
In the human neuroblastoma SH-SY5Y cell line, the glutathione transferase Omega 1-1 (GSTO1-1) appears to modulate Akt and MEK1/2 kinase activation. We observed a glutathionylation modification was involved in the activation of Akt but not MEK1/2. With the specific GSTO1-1 inhibitor ML175, we show the enzyme activity of GSTO1-1 is important for modulation as the inhibited GSTO1-1 allowed activation of both Akt and MEK1/2. The inhibition of GSTO1-1 showed a similar extent of activation of Akt and MEK1/2 as treatment by the endotoxin lipopolysaccharide. The GSTO1-1 also either directly interacts with Akt and MEK1/2 or interacts with a protein complexed with Akt and MEK1/2 as both kinases coimmunoprecipitated with GSTO1-1. The results suggest that GSTO1-1 enzyme activity inhibits the activation of these two kinases to maintain basal levels. The possible regulation by GSTO1-1 is of interest as both kinases have hundreds of potential downstream targets that are known to have contributions to various cellular processes including survival, growth, proliferation, and metabolism.
