Hypothesis

Whether AKAP5 and AKAP12 can hetero-oligomerize into supermolecular scaffolds of increased complexity is unknown.

Conclusion

AKAP5 and AKAP12 are capable of forming hetero-oligomeric supermolecular complexes that influence AKAP locale and function.

Supporting Evidence

  • AKAP5 and AKAP12 were shown to form minimally hetero-dimers.
  • The presence of AKAP12 increased the docking of AKAP5 by 4-fold upon stimulation.
  • Steric-exclusion chromatography revealed large supermolecular complexes containing both AKAPs.

Takeaway

This study shows that two proteins, AKAP5 and AKAP12, can stick together in a new way, which helps them work better in sending signals inside cells.

Methodology

Affinity chromatography and steric-exclusion chromatography were used to analyze the interactions and oligomerization of AKAP5 and AKAP12.
