PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	N terminal 19-20AA extension
	thioredoxin-like domains
	a glutathione binding site where glutathione can form a disulfide bond with a conserved active site cysteine residue positioned near the N-terminal end of helix 1
	an active site cysteine residue that is essential for its primary catalytic activities
	seven alpha helices abriting the C terminal

mono polymer

monomer

HOMOLOGY

interspecies

homolog to murine P28

intraspecies

homolog to GSTO2

Homologene

FAMILY

cytosolic glutathione transferase super family

CATEGORY

enzyme

SUBCELLULAR LOCALIZATION	extracellular
	intracellular
	intracellular,cytoplasm,cytosolic

basic FUNCTION	small stress response protein likely involved in cellular redox homeostasis
	implicated in the post-translational processing and activation of the proinflammatory mediator interleukin-1B
	inhibitor of cardiac muscle ryanodine receptor Ca2+ channels
	nuclear translocation could be potentially involved in the stress response of human cells playing a role in the cancer progression of Barrett esophagus
	two isozymes (GSTO1 and GSTO2) have significant DHA reductase (DHAR) activity
	participates in the glutathionylation cycle and targets specific proteins

REGULATION

Other morbid association(s)

Type Gene Modification Chromosome rearrangement Protein expression Protein Function constitutional     --over   appears to be associated with activation of survival pathways (Akt and ERK1/2) and inhibition of apoptotic pathways (JNK1), as well as protection against cisplatin-induced apoptosis

Susceptibility

to variation of the age at onset of Alzheimer disease to hepatocellular carcinoma, cholangiocarcinoma and breast cancer

Variant & Polymorphism insertion/deletion	polymorphic deletion of Glu-155 causes a deficiency of GSTO1 (by its low stability, resulting from its increased propensity to unfold), may contribute to the observed association of GSTO1 with the age at onset of Alzheimer disease
	GSTO1*A140D polymorphism could play an important role as a risk factor for the development ofhepatocellular carcinoma, cholangiocarcinoma and breast cancer
