SAPK1 — Cucumis sativus

Summary

CSA_6G499740, designated SAPK1 in cucumber (Cucumis sativus, chromosome 6), encodes a non-specific serine/threonine protein kinase with ATP-binding and kinase domain signatures, classified as EC 2.7.11.1. The gene is associated with ABA signaling, TOR signaling, stomatal movement, fruit development, seed germination, seedling development, cell cycle, defense response, and osmotic response. It is linked to protein phosphorylation, signal transduction, hormone anabolism, and responses to salinity and abiotic stimuli. The encoded protein localizes to the cytosol, cytoplasm, and nucleus. Associations with drought tolerance, water use efficiency, transpiration rate, and sugar content have been noted. Related genes in other species link the family to abscisic acid-inducible protein kinase activity.
