Description

When NOX4 protein complexes with CYBA/p22phox, superoxide is generated in cells. It regulates signaling cascades and inhibits phosphatases. NOX4 Protein, Human (His) is the recombinant human-derived NOX4, expressed by E. coli Cell-free , with N-10*His labeled tag. ,

Background

NOX4 protein is a constitutive NADPH oxidase that generates superoxide within cells when it forms a complex with CYBA/p22phox. It is involved in regulating signaling cascades, potentially through inhibiting phosphatases. NOX4 may act as an oxygen sensor, influencing the activity of the KCNK3/TASK-1 potassium channel and HIF1A. It may also play a role in regulating insulin signaling, apoptosis, bone resorption, and lipolysaccharide-induced activation of NFKB. Additionally, NOX4 might produce superoxide in the nucleus, contributing to the regulation of gene expression following cell stimulation. Notably, isoform 3 is non-functional, while isoform 5 and isoform 6 exhibit reduced activity. NOX4 is implicated in redox signaling in vascular cells, generating reactive oxygen species (ROS) constitutively and NADPH-dependently. It modulates the activation of ERK1/2 and the ELK1 transcription factor in the nucleus and can induce nuclear DNA damage. Isoform 4, compared to isoform 1, demonstrates increased activity.

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.

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
