53BP1 condensates selectively recruit proteins through a multivalency threshold mechanism where Rif1, containing 12+ SAF domains, acts as a high-valency scaffold that co-assembles with 53BP1 through multiple simultaneous interactions. Low-valency proteins are excluded due to insufficient avidity to overcome interfacial energy barriers. However, the causal role of Rif1 as scaffold vs. client remains unresolved; Rif1 knockout does not disrupt 53BP1 condensate formation itself, suggesting it functi
**Background and Rationale**
Alzheimer's disease (AD) pathogenesis is intimately linked to apolipoprotein E (APOE) isoform-dependent differences in amyloid-beta (Aβ) clearance and lipid metabolism. The APOE4 allele, present in approximately 25% of the population and 65% of AD patients, confers the highest genetic risk for late-onset AD. Unlike APOE2 and APOE3, APOE4 exhibits significantly reduced lipidation capacity and impaired Aβ clearance efficiency. This stems from structural differences in
