Target intelligence / Profile preview

Interferon omega (IFN-ω)

Target
IFN-ω
Molecular classification
Cytokine, Type I Interferon
01

Overview

Interferon omega (IFN-ω) is a type I interferon cytokine involved in immune regulation and antiviral defense. It binds to the IFNAR receptor complex and activates the JAK/STAT signaling pathway, leading to antiviral, antiproliferative, and immunomodulatory effects. It has veterinary applications for treating viral infections in animals but remains investigational for human use.
