NPK1 — Nicotiana attenuata

Summary

A4A49_03367 (NPK1) in coyote tobacco (Nicotiana attenuata) on chromosome scaffold00661 encodes a protein with MAPKK activity, MEKK activity, protein tyrosine kinase activity, Ca2+/CaM-dependent kinase activity, calcium-dependent protein serine/threonine kinase activity, calmodulin binding, calcium ion binding, protein serine kinase activity, protein kinase activity, protein serine/threonine kinase activity, and ATP binding. It is associated with lateral growth, cell localization, regulation of cytokinesis, prophase, M phase, metaphase, mating, interphase, anaphase, pheromone response, cytokinesis, meiosis, DNA anabolism, mitosis, cell plate assembly, MAPK cascade, and inhibition of salinity response. The gene is also linked to drought tolerance. Its product localizes to the membrane, plasmalemma, cytoplasm, and nucleus. Studies of related genes in other species connect the NPK1 family to sugar content and stomatal opening.
