  • Western blot analysis of extracts from RAW264.7 (lane 2(20μg), HepG2 (lane 3(20μg) and Hela (lane 4(20μg) using Keap1 (HY-P80732) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.

  • Immunohistochemical analysis of paraffin-embedded Mouse kidney tissue using Keap1 Antibody. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 2 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HY-P80732, 1/100) in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

背景
功能:BCR (BTB-CUL3-RBX1) E3 泛素连接酶复合物的底物特异性适配器通过靶向 NFE2L2/NRF2 进行泛素化来调节氧化应激反应 (PubMed:14585973, PubMed:15379550, PubMed:15572695, PubMed:15601839, PubMed:15983046, PubMed:37339955)。KEAP1 作为氧化应激和亲电应激的关键传感器:在正常情况下,BCR (KEAP1) 复合物介导 NFE2L2/NRF2 的泛素化和降解,NFE2L2/NRF2 是一种转录因子,可调节许多细胞保护基因的表达 (PubMed:15601839, PubMed:16006525)。为应对氧化应激,不同的亲电代谢物会触发 KEAP1 中高活性半胱氨酸残基的非酶促共价修饰,导致 BCR (KEAP1) 复合物的泛素连接酶活性失活,从而促进 NFE2L2/NRF2 在细胞核内积累并表达 II 期解毒酶 (PubMed:16006525, PubMed:17127771, PubMed:18251510, PubMed:19489739, PubMed:29590092)。为应对选择性自噬,KEAP1 与 SQSTM1/p62 相互作用后被隔离在包涵体中,导致 BCR (KEAP1) 复合物失活并激活 NFE2L2/NRF2 (PubMed:20452972)。 BCR (KEAP1) 复合物还介导 SQSTM1/p62 的泛素化,从而增强 SQSTM1/p62 的螯合活性并促进其降解 (PubMed:28380357)。BCR (KEAP1) 复合物还靶向 BPTF 和 PGAM5,使其泛素化并被蛋白酶体降解 (PubMed:15379550, PubMed:17046835)。
亚细胞定位:细胞质;细胞核
表达水平:
组织特异性:广泛表达,在骨骼肌中含量最高。
亚基:BCR (KEAP1) E3 泛素连接酶复合物的组成部分,至少由 2 个 CUL3 分子、2 个 KEAP1 分子和 RBX1 组成 (PubMed:15572695, PubMed:15601839, PubMed:15983046, PubMed:17127771, PubMed:18251510, PubMed:24896564)。与 NFE2L2/NRF2 相互作用;这种相互作用是直接的 (PubMed:15379550, PubMed:15601839, PubMed:16006525, PubMed:16888629, PubMed:18387606)。与 NFE2L2/NRF2 和 PGAM5 形成三元复合物 (PubMed:17046835)。与 (磷酸化的) SQSTM1/p62 相互作用;这种相互作用是直接的,通过将 BCR (KEAP1) 复合物隔离在包涵体中使其失活,从而促进其降解 (PubMed:20452972, PubMed:20495340)。与 NFE2L1 相互作用 (PubMed:16687406)。与 BPTF 和 PTMA 相互作用 (PubMed:15657435)。与 MAP1LC3B 相互作用 (PubMed:24089205)。与 ENC1 间接相互作用 (PubMed:19424503)。与 SESN1 和 SESN2 相互作用 (PubMed:23274085)。与 HSP90AA1 和 HSP90AB1 相互作用 (PubMed:26517842)。与 PGCKA1 相互作用;这种相互作用可阻止 TRIM25 对 KEAP1 的泛素化,从而保护 KEAP1 免于降解 (PubMed:36882524)。

  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
