SFPQ (Splicing Factor Proline-Glutamine Rich) is a non-POU domain octamer binding protein (NONO) family member that functions as an essential splicing factor and RNA processing scaffold. This hypothesis proposes that in ALS motor neurons, TDP-43 cytoplasmic mislocalization causes partial depletion of nuclear SFPQ from its normal genomic loci, triggering expression of a set of germline-era SFPQ-paralog (PSP1/NONO) genes normally silenced in differentiated neurons. These paralogs compete with SFPQ
This hypothesis proposes that TBK1 loss-of-function mutations drive ALS pathogenesis through a two-step mechanism: first, TBK1-deficient microglia adopt a senescent state and release SASP factors (TNF-α, IL-1β, type I interferons) that act as paracrine stressors on motor neurons; second, these inflammatory signals chronically activate the Integrated Stress Response (ISR) in motor neurons, leading to pathological eIF2α phosphorylation and catastrophic repression of axonal protein synthesis.
