The Drosophila kinesin-I associated protein YETI binds both kinesin subunits.

The microtubule-based motor kinesin-I is essential for the intracellular transport of membrane-bound organelles in the Drosophila nervous system and female germ line. A number of studies have demonstrated that kinesin-I binds to its intracellular cargos through protein-protein interactions between the kinesin tail domain and proteins on the cargo surface. To identify proteins that mediate or regulate kinesin-cargo interactions, we have performed yeast two-hybrid screens of a Drosophila embryonic cDNA library, using the tetratricopeptide repeats of the kinesin light chain and amino acids 675-975 of the kinesin heavy chain as baits. One of the proteins we have identified is YETI. Interestingly, YETI has the unique ability to bind specifically to both subunits of the kinesin tail domain. An epitope-tagged YETI fusion protein, when expressed in Drosophila S2 cultured cells, binds to kinesin-I in copurification assays, suggesting that YETI- kinesin-I interactions are context-independent. Immunostaining of cultured cells expressing YETI shows that YETI accumulates in the nucleus and cytosol. YETI is evolutionarily conserved, and its yeast homolog (AOR1) may have a role in regulating cytoskeletal dynamics or intracellular transport. Collectively, these results demonstrate that YETI interacts with both kinesin subunits of the kinesin tail domain, and is potentially involved in kinesin-dependent transport pathways.[1]
