CCAMK — Nicotiana attenuata

Summary

A4A49_40298 (symbol CCAMK) in coyote tobacco (Nicotiana attenuata) on scaffold06420 encodes a calcium/calmodulin-dependent serine/threonine-protein kinase (EC 2.7.11.17) with CDPK and EF-hand domains, and exhibits calcium-dependent protein serine/threonine kinase activity, calmodulin binding, calcium ion binding, protein serine kinase activity, and ATP binding. The gene is associated with response to symbiont, meiosis, coumarin anabolism, secretion, intracellular signal transduction, microsporogenesis, virus-induced PTGS, and nodulation. It is linked to membrane, plasmalemma, cytoplasm, and nucleus localisation. Associations with plant trait, water use efficiency, and drought tolerance have been noted. Studies of related genes in other species connect the family to calcium/calmodulin-dependent signalling.
