Why does the Christchurch mutation phenocopy ApoE2 protection despite different protein sequences?

OPEN

Both ApoE2 and the Christchurch mutation reduce LDLR binding and confer protection, but it's unclear why structurally different variants produce identical functional outcomes. Understanding this convergent mechanism could identify the minimal structural requirements for neuroprotection. Gap type: unexplained_observation Source paper: Decreased lipidated ApoE-receptor interactions confer protection against pathogenicity of ApoE and its lipid cargoes in lysosomes.
