NPK1 — Nicotiana attenuata

Summary

A4A49_20287 (NPK1) in coyote tobacco (Nicotiana attenuata) on chromosome scaffold00968 encodes a plant MAPKKK with MEKK activity, calcium-dependent protein serine/threonine kinase activity, calmodulin binding, and calcium ion binding. This gene is associated with the MAPK cascade, cytokinesis, cell plate assembly, regulation of cytokinesis, and cell cycle phases including mitosis, meiosis, prophase, metaphase, anaphase, and interphase. It is linked to lateral growth, DNA replication, and pheromone response. The encoded protein localizes to the nucleus, cytoplasm, membrane, nucleolus, cortical microtubule, and microtubule organizing center. NPK1 is associated with drought tolerance. Studies of related genes in other species link the family to sugar content and stomatal opening.
