Scientific background

The A-kinase anchoring protein 12 (AKAP12) belongs to a family of scaffold proteins, which anchor signaling proteins such as PKA in a spatiotemporal manner4. AKAPs generally bind PKA at their N-terminus, while the sequence at their C-terminus determines their spatial location4. To date, more than 50 AKAPs have been identified and perceived to integrate signaling pathways by anchoring multi-protein complexes1.

AKAP12 integrates diverse signaling pathways such as PKA, PKC, and β2-adrenergic receptor7,8. Similar to other members of this protein-family, AKAP12 contains a PKA binding domain. In addition, AKAP12 also contains a docking site for PKC2,6 and a myristoyl acid that sequesters it to the plasma membrane7.

AKAP12 is widely expressed in a variety of tissues with the highest expression in male and female reproductive organs, skeletal muscle, kidneys, and urinary tract5.

One of the most characterized activities of AKAP12 is regulation of the cell cycle3. AKAP12 controls two fundamental cell processes such as the G1/S transition and cytokinesis. In that being said, studies in NIH-3T3 fibroblasts, showed that ectopic expression of AKAP12 reduced cyclin D1 levels and the phosphorylation of its downstream target Rb, and consequently attenuated cell-cycle progression3. Furthermore, in HeLa cells, knockdown of AKAP12 resulted in profound changes in cell morphology, which indicates the inability of cells to divide3.

Given that AKAP12 plays a pivotal role in cell cycle regulation, it is not surprising that in some cases it is involved in cancer malignancies. It is now clear that AKAP12 is a key driver of gastrointestinal cancers such as colorectal cancer and hepatocellular carcinomas8.
