🧪 Overview

Mechanistic Overview


TBK1 Phosphorylation State Creates Phospho-Regulated Peripheral Retention Threshold starts from the claim that modulating TBK1 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview TBK1 Phosphorylation State Creates Phospho-Regulated Peripheral Retention Threshold starts from the claim that modulating TBK1 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview TBK1 Phosphorylation State Creates Phospho-Regulated Peripheral Retention Threshold starts from the claim that TBK1 phosphorylates SQSTM1 (Ser403) and CALCOCO2, enhancing Ub binding affinity. Excessive TBK1 activation causes strong retention at Ub-rich peripheral zones, preventing penetration to Ub-sparse core. Dysregulated TBK1 (ALS/FTD gain-of-function mutations) causes pathological peripheral sequestration. TRIM21 may modulate this axis. Provides testable link between kinase signaling and spatial organization. Framed more explicitly, the hypothesis centers TBK1 within the broader disease setting of neurodegeneration.

IF we pharmacologically inhibit TBK1 kinase activity (AMG47 or TBK1i) by 80% in iPSC-derived motor neurons from ALS/FTD TBK1 GOF carriers, THEN phosphorylated SQSTM1 (p-S403) peripheral foci density will decrease by >50% within 72 hours compared to vehicle-treated isogenic controls.
Predicted outcome: Significant reduction in peripheral SQSTM1 puncta per cell, quantified by high-content confocal imaging; p-S403 signal intensity decreased without tot
Falsification: Peripheral p-SQSTM1 foci density remains unchanged (<20% reduction) despite >80% TBK1 inhibition, indicating phosphorylation state is not the primary driver of peripheral retention.
