Probable plus end-directed motor protein that may function in the NACK-PQR (NPK1-NQK1/MEK1-NRK1) MAP kinase signaling pathway, which is essential for somatic cell cytokinesis, especially for the cell-plate formation and its expansion. May regulate the activity and the localization of NPK1, probably by association through the non-catalytic region of the kinase. During the M phase of the cell cycle (at protein level). Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family. KIN-7 subfamily.
