  • 產(chǎn)品描述：
    大鼠γ谷氨酰轉(zhuǎn)肽酶1(GGT1)酶聯(lián)免疫試劑盒（CSB-EL009394RA）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的GGT1含量。GGT1是一種編碼γ-谷氨酰轉(zhuǎn)肽酶的基因，該酶是一種質(zhì)膜關(guān)聯(lián)的酶，參與谷胱甘肽的代謝。GGT1基因存在多種轉(zhuǎn)錄本和蛋白質(zhì)變體，其功能與糖尿病和其他代謝性疾病有關(guān)。研究顯示，GGT1基因突變可能引起高GGT血癥，但臨床無相關(guān)癥狀。試劑盒檢測范圍為4.7 mIU/mL-300 mIU/mL，可為肝臟疾病模型研究、藥物肝毒性評估、膽道功能相關(guān)分子機(jī)制探索等科研項(xiàng)目提供可靠數(shù)據(jù)支持本品僅用于科研，不用于臨床診斷，產(chǎn)品具體參數(shù)及操作步驟詳見產(chǎn)品說明書。

靶點(diǎn)詳情

  • 功能：
    Cleaves the gamma-glutamyl bond of extracellular glutathione (gamma-Glu-Cys-Gly), glutathione conjugates and other gamma-glutamyl compounds, such as leukotriene C4 (LTC4). The metabolism of glutathione by GGT1 releases free glutamate and the dipeptide cysteinyl-glycine, which is hydrolyzed to cysteine and glycine by dipeptidases. In the presence of high concentrations of dipeptides and some amino acids, can also catalyze a transpeptidation reaction, transferring the gamma-glutamyl moiety to an acceptor amino acid to form a new gamma-glutamyl compound. Contributes to cysteine homeostasis, glutathione homeostasis and in the conversion of the leukotriene LTC4 to LTD4.
  • 基因功能參考文獻(xiàn)：
    1. an extensive ductular reaction in advanced Hepatocellular carcinoma (HCC) and a strong correlation between PCK7 and levels of gammaGT and the poor prognosis and aggressiveness of HCC, is reported. PMID: 27525410
    2. These data demonstrate the important role of endothelial GGT activity in mediating the vasorelaxant effect of S-nitrosoglutathione in rat aorta . PMID: 22984412
    3. The expression of gamma-glutamyltransferase in rat colon carcinoma cells is distinctly regulated during differentiation and oxidative stress PMID: 12030384
    4. Radiation of CC531 colon carcinoma cells blocked cell proliferation, increased cellular size, initiated apoptosis and upregulated GGT activity and protein levels in a dose- and time-related manner. PMID: 16386375
    5. With the co-existence of inflammation and hypoxia in the brain after ischemic stroke, dynamic changes of gammaGT activity reflect evolving changes of endothelial function. PMID: 16973162
    6. Data suggest that extracellular glutathione elicits gamma-glutamyl transpeptidase and ROS-dependent transactivation of tyrosine kinase signaling that upregulates potassium channel activity or expression via redox-mediated mechanisms. PMID: 19419996
    7. The acylation reaction of GGT by gamma-glutamyl anilides can apparently be accelerated by either electron-withdrawing or electron-donating substituents, suggesting a concerted mechanism involving kinetic general acid catalysis of aniline departure. PMID: 11601992
