KIF3A interacted with GRIP1 and PSD-95 in mouse retina. A. KIF3A staining showed that KIF3A was expressed in the OPL and IPL (postnatal day 80). B. Western blotting analysis showed that LIRD had no obvious effect on the protein levels of KIF3A. C. Immunoprecipitation analysis showed direct interaction between KIF3A and PSD-95, GRIP1. D. E. Confocal imaging showed that KIF3A co-localized well with PSD-95 (D) and GRIP1 (E) in the new neurites in the ONL; scale = 15 μm (A) or 3 μm (D, E).
