**Molecular Mechanism and Rationale**
The hypothesis centers on a sophisticated intracellular signaling network orchestrated by calcium (Ca²⁺) dynamics at mitochondria-associated membranes (MAMs), where the endoplasmic reticulum (ER) and mitochondria form intimate physical contacts. At the molecular core of this mechanism lies the inositol 1,4,5-trisphosphate receptor type 1 (IP3R1), which serves as the primary Ca²⁺ release channel from ER stores. Upon stimulation by IP3, IP3R1 undergoes confor
## Mechanistic Overview
TBK1-OPTN-NDP52 Phospho-Cascade Coordinates Multi-Organelle Autophagy starts from the claim that modulating TBK1, OPTN (TBC1D7), NDP52/CALCOCO2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The TBK1-OPTN-NDP52 phospho-cascade represents a sophisticated cellular quality control network that orchestrates selective autophagy across multiple organellar compartment
