| Annotation description: | "Immunocytochemistry using cultured hippocampal neurons of Kif3b+/+ mice showed that KIF3B puncta were colocalized with APC and NR2A in dendritic shafts (Fig 1D) and in PSD95-positive spines (Fig 1E)." "Here, using mouse brain lysates, we found that NR2A was specifically immunoprecipitated by an anti-KIF3B antibody (Fig 1A), and KIF3A, KIF3B, and KAP3A were specifically immunoprecipitated by an anti-NR2A antibody (Fig 1B). These data suggested that KIF3A/KIF3B/KAP3 complex dominantly interacted with NR2A, rather than NR2B, proposing that KIF3B transports NR2A. We also found that KIF3B, KIF3A, KAP3A, NR2A, and PSD95 were all immunoprecipitated by an anti-APC antibody (Fig 1C), which suggested an interaction of these proteins with APC as a complex." |

Also shows KIF3B/C in synaptic biochemical fractions and microtubule binding characteristics of KIF3C @ PMID:9450952 KIF3A/B are enriched in the same synaptic biochemical fractions prepared from mouse brain. KIF3A and KIF3B form a heterodimer in vitro that provides plus end--directed motor activity. The KIF3 complex Is a heterotrimeric motor in vivo. @ PMID:7559760 |
