Description

The human GOT2 ELISA Kit is engineered for accurate measurement of human GOT2 levels from samples including serum, plasma, or tissue homogenates. It uses the Sandwich-ELISA mechanism in combination with the enzyme-substrate chromogenic reaction to measure the human GOT2 content in the sample. The color intensity is positively correlated with GOT2 content in the sample. This kit has been validated against standards of sensitivity, specificity, precision, linearity, recovery, and lot-to-lot consistency.

GOT2 is a mitochondrial glutamate oxaloacetate transaminase that catalyzes the irreversible transamination of the L-tryptophan metabolite L-kynurenine to form kynurenic acid (KA). It facilitates the cellular uptake of long-chain free fatty acids. GOT2 plays a key role in amino acid metabolism, intracellular NAD(H) redox balance, as well as metabolite exchange between mitochondria and cytosol. Studies have shown that loss of GOT2 disturbs redox homeostasis and halts the proliferation of pancreatic ductal adenocarcinoma (PDA) cells in vitro.

Target Background

Function
(From Uniprot)
Catalyzes the irreversible transamination of the L-tryptophan metabolite L-kynurenine to form kynurenic acid (KA). As a member of the malate-aspartate shuttle, it has a key role in the intracellular NAD(H) redox balance. Is important for metabolite exchange between mitochondria and cytosol, and for amino acid metabolism. Facilitates cellular uptake of long-chain free fatty acids.

  1. Study utilizing integrative analysis of transcriptomic, metabolomic, and clinical data propose a model of GOT2 transcriptional regulation, in which the cooperative phosphorylation of STAT3 and direct joint binding of STAT3 and p65/NF-kappaB to the proximal GOT2 promoter are important. Furthermore, high aberrant GOT2 expression is prognostic in diffuse large B-cell lymphoma. PMID: 29666362
  2. The results of our study on this larger than 5800-patient cohort suggest beneficial effects of high B12 vitamin level, negative effects of high sodium levels or high AST (aspartate aminotransferase) liver enzyme levels to cognition. PMID: 28918286
  3. Like in adults, FABP seems to be associated with markers of metabolic risk in obese adolescents PMID: 28183455
  4. Data suggest that, in context of abnormal hepatic lipid accumulation in nonalcoholic fatty liver disease, circulating GOT2 rises due to up-regulation of hepatic expression of GOT2 associated with greater gluconeogenesis and insulin resistance. PMID: 26791191
  5. A previously unknown mechanism by which GOT2 acetylation stimulates the malate-aspartate NADH shuttle activity and oxidative protection. PMID: 25755250
  6. High glucose infusion was associated with increased expression of higher plasma membrane-associated fatty acid-binding protein (FABPpm). PMID: 24937540
  7. The lipid binding process in L-FABP is associated with backbone dynamics. PMID: 22713574
  8. Frequency of polymorphism are similar in control groups and schizophrenics. PMID: 17728674
