HSP70/DnaK 蛋白, E. coli (P.pastoris, His)

The HSP70/DnaK protein is a molecular chaperone that primarily responds to stress, especially heat shock. It plays a crucial role in helping proteins fold correctly and prevent misfolding or aggregation during cellular stress. HSP70/DnaK Protein, E. coli (P.pastoris, His) is the recombinant E. coli-derived HSP70/DnaK protein, expressed by P. pastoris , with N-6*His labeled tag. The total length of HSP70/DnaK Protein, E. coli (P.pastoris, His) is 638 a.a., with molecular weight of ~71.1 kDa.

HSP70/DnaK 蛋白作为分子伴侣，主要响应热休克等应激条件。在细胞应激时，这种蛋白质在协助其他蛋白质正确折叠、防止错误折叠或聚集方面发挥着至关重要的作用。HSP70/DnaK 的伴侣活性对于细胞稳态和在不利环境条件下的生存尤其重要，在这种条件下维持蛋白质的正确构象变得具有挑战性。该蛋白质识别并协助错误折叠或变性蛋白质重折叠的能力对于细胞弹性和预防各种应激源（特别是高温）引起的蛋白质毒性至关重要。
