AKT1 messenger RNA 3' untranslated region (AKT1 3'UTR)

The AKT1 messenger RNA 3' untranslated region (3'UTR) is a critical regulatory segment located downstream of the coding sequence of the AKT1 gene, which encodes the RAC-alpha serine/threonine-protein kinase (NCBI Gene ID: 207). This region acts as a scaffold for the binding of microRNAs (miRNAs) and RNA-binding proteins (RBPs) that control the stability and translational efficiency of the AKT1 transcript (PubMed: 23563738). In various cancers, the loss of tumor-suppressive miRNAs that normally target the AKT1 3'UTR, such as miR-199a or miR-149, leads to the overexpression of the AKT1 protein and subsequent hyperactivation of the PI3K/AKT/mTOR signaling pathway (PubMed: 25116393). As a therapeutic target, the AKT1 3'UTR is being explored for the development of RNA-based therapeutics, including antisense oligonucleotides (ASOs) and miRNA mimics, which aim to downregulate AKT1 at the pre-translational level. This approach offers a potential advantage over traditional small-molecule kinase inhibitors by reducing total protein levels and potentially achieving higher isoform selectivity. Research is also investigating the role of secondary structures within the 3'UTR, such as G-quadruplexes, as binding sites for small molecules to modulate AKT1 expression in metabolic and oncogenic diseases (PubMed: 30217958).
