Figure 3From: Apolipoprotein E4 (1–272) fragment is associated with mitochondrial proteins and affects mitochondrial function in neuronal cellsApoE4 interacts with the subunits of mitochondrial respiratory complex IV in Neuro2a cells. Neuro2a cells were co-transfected with FLAG-apoE4 (1–272 or 1–299) plasmids and mammalian expression plasmids encoding the candidate apoE4-associated proteins. The cells were treated with 500 μl of Triton X-100 solubilization buffer and the cell lysate was incubated with anti-FLAG M2-agarose affinity resin. The immunoprecipitates were then analyzed by western blotting with an anti-COX IV 1 antibody (human COX IV 1).Back to article page
