NPK1 — Nicotiana attenuata

Summary

A4A49_27523 (NPK1) in coyote tobacco (Nicotiana attenuata) encodes a protein with a Plant_MAPKKK domain and serine/threonine kinase activity, annotated 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, and regulation of cytokinesis, as well as lateral growth, cell localization, and various cell cycle phases including mitosis, meiosis, prophase, metaphase, anaphase, and interphase. It is linked to drought tolerance and related genes ANP1 and ANP3. The protein localizes to the cortical microtubule, membrane, cytoplasm, and nucleus. Studies of related genes in other species connect the family to sugar content and stomatal opening.
