Human Triosephosphate isomerase(TPI1) ELISA kit

Triosephosphate isomerase is an extremely efficient metabolic enzyme that catalyzes the interconversion between dihydroxyacetone phosphate (DHAP) and D-glyceraldehyde-3-phosphate (G3P) in glycolysis and gluconeogenesis.; It is also responsible for the non-negligible production of methylglyoxal a reactive cytotoxic side-product that modifies and can alter proteins, DNA and lipids.

7. results suggest amyloid-beta oligomers induce neuronal death by triggering methylglyoxal(MG) production; increased release of MG is a direct consequence of triosephosphate isomerase nitrotyrosination due to amyloid-beta peptide action at the 2 tyrosines associated with the catalytic center PMID: 24614897

12. study found promoter SNPs of CKB and TPI1 were weakly associated with schizophrenia;in addition, IFNG polymorphisms were associated with schizophrenia; results suggest that IFNG and proteins affected by IFNG may play a role in the pathogenesis of schizophrenia PMID: 22623148
13. [Review] The activity of glycolytic enzyme TPI reveals a mechanistic link between energy metabolism and age-related proteostatic dysfunction which can suppress generation of altered proteins that characterize the aged phenotype in cells and tissues. PMID: 21651995
14. A patient with triosephosphate isomerase-deficiency was found to be homozygous for a Val231Met mutation. PMID: 21215915
15. A proteomic approach for identification and localization of the pericellular components of chondrocytes. PMID: 21698479
16. structural changes rather than abnormal catalysis may play an important role in the clinical manifestations of TPI deficiency; the postulated high aggregation ability of the unstable Glu104Asp mutant would lead to more serious symptoms PMID: 20546019
17. TPI1 were up-regulated with the malignancy of prostate cancer cell lines and have their potential as serum biomarkers for indicating the developmental stage of prostate cancer. PMID: 20233700
18. of two previously undescribed mutations: c.722 T>C (Phe240Ser) and c.28 insG; each of the two unrelated patients showed the new mutation in compound heterozygosity with the most common variant Glu104Asp, resulting in a very severe clinical pattern. PMID: 20374271
19. the dimerization behavior of TPI is influenced by the particular mutations investigated, and by the use of a potential alternative translation initiation site in the TPI gene PMID: 17183658
20. kinetic, thermodynamic, structural and ultrastructural data for characterization of mutant isomerase structures and for the TPI-related metabolic processes in normal and deficient cells PMID: 12023819
21. Minor structural changes in a mutated human melanoma antigen (TPI) correspond to dramatically enhanced stimulation of a CD4+ tumor-infiltrating lymphocyte line. PMID: 12051920
22. A patient with triosephosphate isomerase (TPI) deficiency exhibited worsening of abnormal involuntary movements of the dystonic type and developed psychiatric symptoms while on selegiline. PMID: 14743370
23. IgG-type anti-TPI autoantibodies were detected in 24.7% of the serum samples and 24.1% of the synovial fluid samples from the patients with osteoarthritis PMID: 15146421
24. anti-TPI antibodies are closely associated with neuropsychiatric lupus PMID: 15358119
25. We found that a low TPI activity in the mutant cells (lower than predicted from the protein level and specific activity of the purified recombinant enzyme) is coupled with an increase in the activities of glycolytic kinases PMID: 16086671
26. Mutations causing TPI deficiency in humans are characterized by progressive neurological dysfunction, neurodegeneration, and early death. PMID: 17008404
27. TPI and GAPDH may be candidate Ags for an autoimmune response to neurons and axons in multiple sclerosis. PMID: 17015754
28. anti-TPI form immune complexes in CSF and contribute to the pathogenesis of neuropsychiatric lupus by activating the complement system PMID: 17064784
