- 6. An expression vector comprising a nucleic acid encoding a microtubule motor protein, wherein the motor protein has the following properties: (i) the protein's activity includes microtubule depolymerization activity; and (ii) the protein has a sequence that has greater than 70% amino acid sequence identity to SEQ ID NO:2 as measured using a sequence comparison algorithm.
- 7. A host cell transfected with the vector of claim 6.
- 8. An isolated microtubule motor protein, wherein the protein has greater than 70% amino acid sequence identity to SEQ ID NO:2 as measured using a sequence comparison algorithm.
- 9. An isolated protein of claim 8, wherein the protein specifically binds to polyclonal antibodies to KinI-3.
- 10. An isolated protein of claim 8, wherein the protein is KinI-3.
- 11. An isolated protein of claim 8, wherein the protein has an amino acid sequence of SEQ ID NO:2.
- 12. An isolated protein of claim 8, wherein the protein specifically binds to polyclonal antibodies generated against a motor domain of KinI-3.
