JAK1 Protein, Human (P. pastoris, His)

Cat. No.: HY-P700583
COA Handling Instructions

JAK1 protein is a non-receptor tyrosine kinase that plays a crucial role in IFN-α/β/γ signaling and serves as a kinase partner for IL-2 and IL-10 receptors. It cooperates with the type I interferon receptor IFNAR2 to phosphorylate and activate IFNAR2 upon interferon binding to IFNAR1-IFNAR2. JAK1 Protein, Human (P. pastoris, His) is the recombinant human-derived JAK1 protein, expressed by P. pastoris , with N-6*His labeled tag. The total length of JAK1 Protein, Human (P. pastoris, His) is 305 a.a., with molecular weight of 36.9 kDa.

Description

JAK1 protein is a non-receptor tyrosine kinase that plays a crucial role in IFN-α/β/γ signaling and serves as a kinase partner for IL-2 and IL-10 receptors. It cooperates with the type I interferon receptor IFNAR2 to phosphorylate and activate IFNAR2 upon interferon binding to IFNAR1-IFNAR2. JAK1 Protein, Human (P. pastoris, His) is the recombinant human-derived JAK1 protein, expressed by P. pastoris , with N-6*His labeled tag. The total length of JAK1 Protein, Human (P. pastoris, His) is 305 a.a., with molecular weight of 36.9 kDa.

Background

JAK1 protein, a non-receptor tyrosine kinase, plays a crucial role in the IFN-alpha/beta/gamma signal pathway, as evidenced by various studies. It acts as a kinase partner for the interleukin (IL)-2 receptor and IL-10 receptor, demonstrating its versatility in different cytokine signaling pathways. Moreover, JAK1 serves as a kinase partner for the type I interferon receptor IFNAR2, and upon interferon binding to the IFNAR1-IFNAR2 heterodimer, it phosphorylates and activates IFNAR2, creating docking sites for STAT proteins. JAK1 not only directly phosphorylates STAT proteins but also activates STAT signaling by transactivating other JAK kinases associated with signaling receptors. This multifaceted involvement positions JAK1 as a central player in the intricate network of signaling pathways, contributing to the regulation of immune responses and cellular processes.

Help & FAQs
  • 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.

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
