CK2 constitutively phosphorylates G3BP1 at multiple serine/threonine residues (S149, T232, S238). In neurodegenerative conditions, stress-activated CK2 activity is dysregulated, leading to hyperphosphorylation that creates steric hindrance around the N-terminal regulatory domain where TRIM21 binds, preventing ubiquitination while leaving SG assembly functions intact. This hypothesis was deprioritized (confidence 0.48) because phosphorylation typically creates binding sites for reader proteins ra
**Background and Rationale** TREM2 variants represent major genetic risk factors for Alzheimer's disease, with loss-of-function mutations increasing dementia risk threefold. While TREM2 is exclusively expressed on microglia, emerging evidence suggests its primary pathogenic role occurs through disrupted astrocyte-microglia communication rather than intrinsic microglial dysfunction. Healthy brain homeostasis depends on coordinated responses between these glial populations, where TREM2+ microglia
