TGF-beta activated kinase 1-binding protein 2 mRNA (TAB2 mRNA)

TGF-beta activated kinase 1-binding protein 2 (TAB2) mRNA is the messenger RNA transcript encoding a crucial adaptor protein that facilitates intracellular signaling within the TAK1 complex. The resulting TAB2 protein acts as a scaffold, bridging K63-linked polyubiquitin chains to the TAK1 kinase, which is essential for the activation of the NF-kappaB and mitogen-activated protein kinase (MAPK) pathways in response to pro-inflammatory cytokines like IL-1 and TNF-alpha [1, 5, 8]. This signaling axis is fundamental for normal immune responses and cardiovascular development; however, its dysregulation is associated with significant pathologies. Upregulation of TAB2 mRNA is documented in various cancers, such as head and neck squamous cell carcinoma and gastric cancer, where it promotes tumor cell proliferation and epithelial-mesenchymal transition (EMT) [2, 3]. Conversely, mutations or haploinsufficiency of the TAB2 transcript are linked to human congenital heart defects, including bicuspid aortic valve and mitral valve prolapse [1, 14]. While no approved pharmaceutical agents currently target TAB2 mRNA, it is an active area of investigation for RNA-based therapeutics, including small interfering RNAs (siRNAs) and antisense oligonucleotides (ASOs), aimed at modulating chronic inflammation and inhibiting tumor progression [4, 13, 16].
