Background: Kinase suppressor of Ras 2 (KSR2) gene codes for a scaffold protein modulating intracellular pathways that involve MEK/BRAF cascade and AMPK signaling. KSR2 plays an important role in energy balance regulation, and KSR2 mutations were reported to be associated with obesity and insulin resistance in mice and humans. In transfected cells, several KSR2 mutations lead to impaired fatty acid oxidation, which improved under met...
