TIA1 (TIA-1) is an essential stress granule (SG) nucleator that undergoes oxidation-sensitive conformational changes in its low-complexity (LC) domain, modulating SG assembly dynamics. This hypothesis proposes that in ALS motor neurons, chronic oxidative stress (elevated ROS, mitochondrial dysfunction) causes irreversible oxidation of TIA1's LC domain cysteines, locking TIA1 into a hyper-assembly state that nucleates aberrant, gel-like SGs with altered material properties. These oxidized TIA1-SG

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
