NPK1 — Nicotiana attenuata

Summary

A4A49_35978 (NPK1) in coyote tobacco (Nicotiana attenuata) on chromosome scaffold04692 encodes a plant MAPKKK family protein with protein serine/threonine kinase activity, calcium/calmodulin-dependent kinase activity, MEKK activity, and calmodulin binding. It is associated with the MAPK cascade, cytokinesis, cell plate assembly, regulation of cytokinesis, mitosis, meiosis, prophase, metaphase, anaphase, interphase, M phase, DNA replication, lateral growth, cell localization, mating, and pheromone response. The gene is linked to drought tolerance and to the related gene ANP2. It localizes to the nucleus, cytoplasm, membrane, plasmalemma, nucleolus, and microtubule organizing center. Related genes in other species link the family to MAPK signaling and cell cycle regulation.
