CRK — Daucus carota subsp. sativus

Summary

DCAR_025717 (DcCRK, also known as DcCRK5 or DcTAGK2) on carrot chromosome 7 encodes a calcium-dependent protein kinase (CDPK) with serine/threonine and tyrosine kinase activities, calmodulin binding, calcium ion binding, and mRNA binding, and it also is annotated as a structural constituent of the cytoskeleton. The gene is associated with microtubule-based processes, intracellular signal transduction, protein autophosphorylation, and responses to cold, thirst, and fungal defence. It is linked to upregulation of gibberellic acid-mediated signalling, activation of the salinity response, and traits including gibberellic acid sensitivity, root morphology, and salt tolerance. The encoded protein localises to the tubulin complex, vacuole, plant-type cell wall, Golgi, plasmodesmata, membrane, cytosol, and plasmalemma. Studies of related genes in other species connect the family to microtubule formation, cold and salt stress tolerance, abscisic acid response, and biotic stress resistance.
