Kinesin-like protein KIF17 is a protein that in humans is encoded by the KIF17 gene.[5][6] KIF17 and its close relative, C. elegans OSM-3,[7] are members of the kinesin-2 family of plus-end directed microtubule-based motor proteins.[8] In contrast to heterotrimeric kinesin-2 motors,[9] however, KIF17 and OSM-3 form distinct homodimeric complexes.[10] Homodimeric kinesin-2 has been implicated in the transport of NMDA receptors along dendrites for delivery to the dendritic membrane,[5] whereas both heterotrimeric and homodimeric kinesin-2 motors function cooperatively in anterograde intraflagellar transport (IFT) and cilium biogenesis.[11][12]
