    basic FUNCTION
  • basic ciliary activity-putatively involved in the nodal flow supposed to break symetry
  • kinesin-2 complex (KIF3A, KIF3B) plays an important role not only in interphase but also in mitosis
  • PKP4 and ECT2 are transported via distinct motors, identifying a novel pathway implicating KIF3B in the regulation of actin organization during cytokinesis
  • heterotrimeric motor protein that facilitates fast anterograde translocation of membranous organelles
  • involved in the trafficking of SLC4A1 to the plasma membrane of kidney alpha-intercalated cells
  • playing a role in SLC4A1 trafficking to the plasma membrane
  • KIF3B mutant photoreceptor cilia differentiate with a delay, suggesting that KIF3C, although redundant with KIF3B at later stages of differentiation, is not active early in photoreceptor ciliogenesis
  • KIF3A, KIF3B (KIF3AB) is an N-terminal processive kinesin-2 family member best known for its role in intraflagellar transport
  • the kinesin-2 family motor KIF3A/KIF3B works together with dynein to bidirectionally transport intraflagellar particles, melanosomes, and neuronal vesicles
  • KIF3A, KIF3B, KIF3C is classified as a heterotrimeric kinesin-2 that is best known for organelle transport in neurons

    a component
  • heterodimere of KIF3A and KIF3P
    small molecule
  • CSPG6
  • associating with PKHD1 and PKD2 (mediates the regulation of PKD2 channel function by PKHD1)
  • interaction with ARHGEF10 (KIF3B may modulate the ARHGEF10-RhoA pathway through the binding to ARHGEF10)
  • CLCN5 interacts with kinesin family member 3B (C-terminus of CLCN5 and the coiled-coil and globular domains of KIF3B were shown to interact) (KIF3B)
  • SLC4A1 interacts with KIF3B in the kidney tissue (a dileucine motif at the C-terminal SLC4A1 contributes to its interaction with KIF3B)
  • RNF33 most likely interacted with KIF3A-KIF3B independent of the adaptor kinesin-associated protein KIFAP3
  • GLI1 interactions with KIF3A-KIF3B-KIFAP3 complexes are essential for proper GLI1 transcriptional activity
  • PKP4 directly interacts with the KIF3/subunit KIF3B, and also interacts with the kinesin cargo adaptor protein KIFAP3 acting as a stabilizing linker between KIF3B and its KIFAP3 cargo binding entity
