Kinase involved in negative regulation of abscisic acid (ABA) signaling. Substrate preference is farnesol > geraniol > geranylgeraniol, but has no activity with farnesyl phosphate. Can use CTP > ATP > GTP = UTP as phosphoryl donor. (2E,6E)-farnesol + CTP = (2E,6E)-farnesyl phosphate + CDP + H(+) (2E,6E)-farnesol + ATP = (2E,6E)-farnesyl phosphate + ADP + H(+) (2E)-geraniol + ATP = (2E)-geranyl phosphate + ADP + H(+) (2E,6E,10E)-geranylgeraniol + ATP = (2E,6E,10E)-geranylgeranyl phosphate + ADP + H(+) Down-regulated by abscisic acid. Increased sensitivity to abscisic acid. Belongs to the polyprenol kinase family.
