This hypothesis proposes that loss-of-function mutations in TBK1 contribute to ALS pathogenesis primarily through disrupted mitochondrial quality control in motor neurons, leading to bioenergetic failure and selective neuronal death. TBK1 normally phosphorylates autophagy receptors OPTN and p62, which are essential for targeting damaged mitochondria for mitophagy. When TBK1 function is lost, defective mitochondria accumulate in motor neurons, causing oxidative stress, ATP depletion, and ultimate

The Integrated Stress Response (ISR) controls cellular protein synthesis through eIF2α phosphorylation, but this hypothesis proposes that chronic ISR activation in ALS motor neurons creates a pathological cascade that specifically disrupts mitochondrial protein homeostasis and bioenergetics. In ALS, chronic eIF2α~P elevation (>0.7 normalized phosphorylation) caused by proteostatic stress from TDP-43/FUS aggregates selectively impairs synthesis of nuclear-encoded mitochondrial proteins, including
