Janus kinase 2/JAK2 蛋白, Human (His)

Janus kinase 2/JAK2 Protein, Human (His) is a recombinant human JAK2 expressed in E. coli with a His tag at the N-terminus. JAK2 is a non-receptor tyrosine kinase^[1][2].

JAK2 是非受体蛋白酪氨酸激酶 Janus 激酶 (JAK) 家族的成员，该家族包括 JAK1-3 和 TYK2。JAK 作为细胞因子受体的细胞质信号传导成分，通过细胞因子介导的转磷酸化被激活，从而导致受体磷酸化以及信号转导子和转录激活子 (STAT) 蛋白的募集和磷酸化。JAK 是非受体蛋白酪氨酸激酶，作为多种细胞因子受体的催化信号传导成分，包括白细胞介素、干扰素、生长激素、促红细胞生成素和瘦素的受体^[1][2]。

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
