產品詳情

  • 產品描述：
    DNAJA1 Recombinant Monoclonal Antibody（CSB-RA589492A0HU）是一款經多種實驗驗證的高特異性抗體，靶向DNAJA1蛋白。DNAJA1是Hsp40/DnaJ分子伴侶家族成員，通過調節Hsp70 ATP酶活性參與蛋白質折疊、應激反應及錯誤蛋白降解，其表達異常與腫瘤發生、神經退行性疾病等病理過程密切相關。本抗體經ELISA、Western Blot（WB）、免疫熒光（IF）和流式細胞術（FC）嚴格驗證，在WB實驗中可清晰識別內源性DNAJA1蛋白，IF與FC實驗能精準定位細胞內及膜表面靶蛋白分布，推薦稀釋度分別為WB 1:500-1:2000、IF 1:50-1:200、FC 1:50-1:200。驗證數據表明該抗體在多種樣本類型中均呈現低背景和高信噪比特性，適用于研究DNAJA1在細胞應激應答、蛋白質質量控制機制中的功能，或用于體外模型中探索其與Hsp70協同作用對疾病相關蛋白聚集的調控。該產品為研究分子伴侶網絡、疾病相關蛋白質穩態失衡提供可靠工具，適用于基礎科研領域的蛋白互作分析、亞細胞定位研究及功能驗證實驗。

靶點詳情

  • 功能：
    Co-chaperone for HSPA8/Hsc70. Stimulates ATP hydrolysis, but not the folding of unfolded proteins mediated by HSPA1A (in vitro). Plays a role in protein transport into mitochondria via its role as co-chaperone. Functions as co-chaperone for HSPA1B and negatively regulates the translocation of BAX from the cytosol to mitochondria in response to cellular stress, thereby protecting cells against apoptosis. Promotes apoptosis in response to cellular stress mediated by exposure to anisomycin or UV.

    1. that DNAJA1 controls the fate of misfolded stabilization of mutant p53 PMID: 27775703
    2. Therefore, we propose that DnaJA1 is co-opted by the influenza A virus to enter the nucleus and to enhance its RNA polymerase activity in an Hsp70 cochaperone-independent manner. PMID: 25253355
    3. structure and function of human DNAJA1 and its relationship to pancreatic cancer PMID: 24512202
    4. we combined the Hsp70-NEF pairs with cochaperones of the J protein family (DnaJA1, DnaJA2, DnaJB1, and DnaJB4) to generate 16 permutations. PMID: 24318877
    5. Moreover, the levels of DnaJA1 and Hsp70 seem to play against each other with regard to tau: as DnaJA1 levels increase, tau levels are reduced, but this can be prevented if Hsp70 levels are simultaneously induced. PMID: 22343013
    6. Hdj2 directly associates with Japanese encephalitis virus nonstructural protein NS5 and facilitates viral replication. PMID: 21999493
    7. Hsc70 and a dimer of DjA1 independently bind to an unfolded protein PMID: 20363747
    8. Hsp40 type 1 chaperones DJA1 (DNAJA1/Hdj2) and DJA2 (DNAJA2) as key modulators of hERG degradation PMID: 19940115

    11. sequence analysis of two isoforms PMID: 12974469
