Immunopharmacology Comments
Ikkα is one of the catalytic subunits of the IκB kinase (IKK) complex, an upstream component of the NF-κB signal transduction cascade; NF-κB signaling being involved in propagating the cellular response to inflammation. IKK frees NF-κB from its inhibitory interaction with IκBα (inhibitor of kappa B), allowing NF-κB translocation to the nucleus where it modulates transcriptional activity. Additional functions of Ikkα beyond NF-κB activation are reviewed in [7].
