Kar3p Kinesin-14 Depolymerizing note: Kar3p has two different cofactors; Cik1 for mating cells and Vik1 for vegetatively growing cells None Meluh and Rose, 1990; Endow et al., 1994; Manning et al., 1999; Sproul et al., 2005

Kip3p has variously been placed in the kinesin-8/-13 families by different investigators and has occasionally been described as a KinI kinesin.
