WARS 蛋白, Human (sf9, His)

WARS includes isomer 1, isomer 2, T1-TrpRS and T2-TrpRS, and has aminoacylation activity, except T2-TrpRS. Unlike isoform 1, isoform 2, T1-TrpRS and T2-TrpRS, exhibit vasostatic activity. WARS Protein, Human (sf9, His) is the recombinant human-derived WARS protein, expressed by Sf9 insect cells , with C-His labeled tag. The total length of WARS Protein, Human (sf9, His) is 470 a.a., with molecular weight of ~55 kDa.

WARS 包括异构体 1、异构体 2、T1-TrpRS 和 T2-TrpRS，显示出氨酰化活性，但 T2-TrpRS 是例外，因为它缺乏这种酶促功能。就血管抑制活性而言，Isoform 2、T1-TrpRS和T2-TrpRS表现出这种特性，而Isoform 1不具有血管抑制能力。特别是，T2-TrpRS 通过抑制内皮细胞中流体剪切应力激活的反应而脱颖而出。WARS 在调节关键信号通路中发挥着关键作用，包括 ERK、Akt 和 eNOS 激活，这些信号通路与血管生成、细胞骨架重组和响应剪切应力的基因表达相关。这种多方面的功能强调了 WARS 参与复杂的细胞过程及其对血管反应的潜在影响。
