Inhibitor of nuclear factor kappa-B kinase subunit alpha mRNA (IKKα mRNA)

Inhibitor of nuclear factor kappa-B kinase subunit alpha (IKKα) mRNA is the transcript of the CHUK gene, which encodes a critical serine/threonine kinase involved in the NF-κB signaling pathway [1] (UniProt O15111). Unlike its counterpart IKKβ, the protein translated from this mRNA is the primary regulator of the non-canonical NF-κB pathway, facilitating the processing of p100 into the active p52 subunit [2] (NCBI Gene ID: 1147). Beyond its cytoplasmic kinase activity, IKKα also translocates to the nucleus where it modulates gene expression through histone H3 phosphorylation and interaction with various transcription factors [3] (PubMed: 15630443). In several malignancies, including prostate and breast cancers, IKKα is frequently overexpressed, promoting tumor cell survival, metastasis, and resistance to therapy [4] (PubMed: 22431510). Consequently, IKKα mRNA has become a target for RNA-based therapeutic strategies, such as siRNAs and antisense oligonucleotides, which aim to deplete the protein and inhibit both its signaling and nuclear functions. However, therapeutic development must address challenges such as the essential role of IKKα in skin differentiation and the potential for broad immunosuppressive effects [5] (PubMed: 11029002).
