Annotation description:Fig.3: "PACSIN1 knockdown reduces NMDA-induced GluA2 internalization"
- "These data indicate that PACSIN1 may not regulate AMPAR trafficking under basal conditions."
- " the amount of internalized myc-GluA2 was significantly reduced in PACSIN1 knockdown neurons compared with control neurons (internalization index, pSuper, 1 ± 0.04; sh#1, 0.68 ± 0.03) (Fig. 3 E and F). The reduction in NMDA-induced myc-GluA2 internalization caused by PACSIN1 shRNA could be fully rescued by the expression of an shRNA-resistant PACSIN1 rescue construct in the hippocampal neurons (0.92 ± 0.05) (Fig. 3 E and F). "

Fig.4: "PICK1 binding to the PACSIN1-variable region is required for activity-dependent GluA2 internalization"
- "there was a significant decrease in intracellular myc-GluA2 following NMDA stimulation in neurons that were transfected with HA-PACSIN1 tmE, which had reduced binding with PICK1 (0.84 ± 0.03) (Fig. 4 D and E)."
