Nuclear factor kappa-B kinase subunit alpha/beta (IKK-α/IKK-β)

The IκB kinase complex consists of two main catalytic subunits—inhibitor of nuclear factor kappa-B kinase subunit alpha (IKK-α) and inhibitor of nuclear factor kappa-B kinase subunit beta (IKK-β)—as well as a regulatory subunit (NEMO/IKK-γ). Both alpha and beta subunits are serine/threonine kinases that phosphorylate IκB proteins, leading to their degradation and release of NF-κB, a transcription factor that activates genes involved in immunity, inflammation, cell proliferation, and survival. While both subunits are structurally similar and form part of the same complex, they have distinct roles in the classical and non-canonical NF-κB pathways, and are implicated in a range of diseases including cancer, inflammation, and neurodegeneration. Inhibitors selectively targeting IKK-β have shown potential as anti-inflammatory and anti-cancer agents. Note: The requested target designation, "Nuclear factor kappa-B kinase subunit alpha/beta", is not standard. For precise, structured data, use "Inhibitor of nuclear factor kappa-B kinase subunit alpha" and/or "Inhibitor of nuclear factor kappa-B kinase subunit beta" independently, as most drug discovery databases and scientific literature treat these as separate entities with distinct biological and pharmacological profiles.
