Kinesin-like motor protein that exhibits microtubule-stimulated ATPase activity. Plays an essential role in male meiotic chromosomal dynamics, male gametogenesis and anther dehiscence. May play a minor and nonessential role in regulating meiotic spindle formation. Widely expressed. Expressed in young roots and leaves, in mature roots, culm, sheath and leaves, and in panicles at various developmental stages. Strongest expression is detected in panicles. In the panicle, expression is detected in anthers, glumme, lemma and palea. In the spikelet, expression is detected in both microsporocyte and the anther walls. Expressed during plant development. During young panicle development, highest expression is observed at P4-P5 stages followed by a gradual decline until becomes nearly undetectable at 8 days after heading. Expression is significantly up-regulated during anther development and peaks during male meiosis. Expression disappears in postmeiosis anther. Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family. KIN-1 subfamily.
