Y. Machida et al., MAPKKK-RELATED PROTEIN-KINASE NPK1 - REGULATION OF THE M-PHASE OF PLANT-CELL CYCLE, Journal of plant research, 111(1102), 1998, pp. 243-246
The tobacco NPK1 gene encodes a homolog of mitogen-activated protein k
inase kinase kinases. We have recently identified tobacco kinesin-like
proteins (NACK1/2) as activators for NPK1. Immunochemical analyses of
NPK1 and NACK1 proteins suggest that NPK1 is involved in the regulati
on of some process in the M phase of the plant cell cycle.
