產品描述：

CSB-RA176658A0HU AHCY重組單克隆抗體是針對人源S-腺苷同型半胱氨酸水解酶（AHCY）研發的高特異性檢測工具。該抗體靶向的AHCY蛋白是甲基化代謝通路的核心酶，負責催化S-腺苷同型半胱氨酸轉化為同型半胱氨酸，參與調控細胞內甲基供體動態平衡及表觀遺傳修飾過程。經嚴格驗證，本抗體在ELISA和免疫印跡（WB）實驗中展現出優異的性能，其WB推薦使用稀釋比例為1:500至1:2000，可在多種細胞或組織樣本中清晰檢測到目標蛋白的預期條帶，且未觀察到顯著交叉反應。該產品適用于探索甲基化相關分子機制、代謝穩態調控及疾病模型中的蛋白表達水平分析，尤其在研究甲基代謝異常相關疾病（如代謝紊亂、腫瘤發生或神經系統疾病）的分子機制中具有重要應用價值。作為重組單克隆抗體，其具備高度批次間一致性，并通過多批次質控確保實驗結果的可靠性和可重復性，為科研工作者提供精準的靶點檢測解決方案。

靶點詳情

功能：

Adenosylhomocysteine is a competitive inhibitor of S-adenosyl-L-methionine-dependent methyl transferase reactions; therefore adenosylhomocysteinase may play a key role in the control of methylations via regulation of the intracellular concentration of adenosylhomocysteine.

1. Results uncover a H19/SAHH circuit involving gene-methylation alterations by carcinogen BaP. PMID: 29772428
2. We investigated previously assumed interaction with AHCY-like-1 protein (AHCYL1), a paralog of AHCY. Indeed, significant interaction between both proteins exists. Additionally, silencing AHCYL1 leads to moderate inhibition of nuclear export of endogenous AHCY. PMID: 28647132
3. We have validated the vectors and confirmed self-association of AHCY, AHCYL1, and galectin-3. In a high-throughput BiFC screen, we identified new AHCY interaction partners: galectin-3 and PUS7L. We also describe additional steps in protein interaction analysis, applied for AHCY-galectin-3 interaction PMID: 27455993
4. In order to enable the development of small molecule AHCY inhibitors as targeted cancer therapeutics we developed an assay based on a RapidFire high-throughput mass spectrometry detection system, which allows the direct measurement of AHCY enzymatic activity. PMID: 28533090
5. SAH hydrolase deficiency can remain asymptomatic in childhood, and the disorder can be associated with early onset hepatocellular carcinoma. PMID: 26527160
6. H19 knockdown activates SAHH, leading to increased DNMT3B-mediated methylation of an lncRNA-encoding gene Nctc1 within the Igf2-H19-Nctc1 locus. PMID: 26687445

10. The simulations of ligand-induced transition revealed that the signal of intrasubunit closure dynamics is transmitted to form intersubunit contacts, which in turn invoke a precise alignment of active site. PMID: 22023331
11. Five active site residues (E156, N181, K186, D190, N191) of AdoHcy hydrolase have been individually mutated to alanine and each engineered enzyme characterized with respect to its redox partial reaction and elimination/addition partial reaction. PMID: 12069606

13. Maintenance of ionizable active-site residues in catalytically suitable protonation states in closed forms of placental AHCY may be assisted by a water chain, stabilized by Asp182, that can import and export protons from and to the environment. PMID: 12590576
14. AdoHcy is involved in adenosine-induced apoptosis by altering gene expression. PMID: 17097637
15. R38W and G123R amino-acid exchanges did not bring about major changes to the catalytic rates. However, circular dichroism analysis showed that both polymorphisms effect the thermal stability. PMID: 17164794
16. SAHH, which is diffuse in the cytoplasm of nonmotile Dictyostelium amoebae and human neutrophils, concentrates with F-actin in pseudopods at the front of motile, chemotaxing cells PMID: 17172447
17. In the case of Hs-SAHH, the slow-binding phase terminates in micromolar affinity, but over a period of hours, the dissociation rate constant decreases until the final equilibrium affinity is in the nanomolar range. PMID: 17447732
18. We found clinically relevant levels of Hcy (0-500 microM) induced elevation of SAH, declination of SAM and SAM/SAH ratio and reduced expression of SAHH and MBD2, but increased activity of DNMT3a and DNMT3b affecting DNA methylation PMID: 17688412
19. The mechanism of action of copper on this enzyme sugges a regulative role for copper on the intracellular activity. PMID: 17892301

21. SAHH from Homo sapiens (Hs-SAHH) and from the parasite Trypanosoma cruzi (Tc-SAHH) are very similar in structure and catalytic properties but differ in the kinetics and thermodynamics of association and dissociation of the cofactor NAD (+) PMID: 18393535

25. These data show that 2-5-fold enhanced AdoHcyase activity is well tolerated by the cell, while greatly enhanced AdoHcyase activity results in adenosine-induced apoptosis. PMID: 18769049
