A-kinase anchoring protein 12 (AKAP12) messenger RNA 3'-untranslated region (AKAP12 mRNA 3'-UTR)

The A-kinase anchoring protein 12 (AKAP12) messenger RNA 3'-untranslated region (3'-UTR) is a critical regulatory domain that controls the post-transcriptional expression of the AKAP12 protein, a major scaffold and tumor suppressor (Gelman, 2010, Genes & Cancer). This 3'-UTR contains multiple conserved binding sites for microRNAs, including miR-125b, miR-103, and miR-107, which negatively regulate AKAP12 levels by inducing mRNA degradation or inhibiting translation (Li et al., 2012, Hepatology; Chen et al., 2015, Oncology Reports). In many human cancers, such as hepatocellular carcinoma and prostate cancer, the AKAP12 3'-UTR is targeted by overexpressed oncogenic microRNAs, leading to the loss of AKAP12-mediated suppression of cell cycle progression and migration. Consequently, this UTR is an emerging therapeutic target for RNA-based drugs, such as antisense oligonucleotides (ASOs) or antagomirs, designed to prevent miRNA binding and restore AKAP12 protein levels. Beyond oncology, the AKAP12 3'-UTR plays a role in maintaining the integrity of the blood-brain barrier and regulating fibrotic responses in the liver and lungs. Targeting this region offers a precise mechanism to modulate signaling pathways involving protein kinase A and C without directly altering the genomic sequence (UniProt P50440).
