LRP binding and NMDAR inhibitory potency of apoE peptides.
Peptide | Kd (µM)a | IC50 (µM)b |
---|---|---|
apoE[133–149] | 0.057 ± 0.002 | 1.3 ± 0.1 |
apoE[143–150] | 0.72 ± 0.21 | 3.3 ± 0.1 |
apoE[145–150] | 15.0 ± 6.0 | 17.5 ± 0.6 |
apoE[133–149/K143,146E] | 6.7 ± 1.7 | >100 |
Values were obtained from SPR-monitored binding of peptides to immobilized LRP.
Concentration of peptide needed to achieve 50% inhibition of NMDA/glycine-evoked currents in NR1b/2A-transfected HEK293 cells.
