HSP70 — Cucumis sativus

Summary

CSA_2G070310 (HSP70) in cucumber (Cucumis sativus) on chromosome 2 encodes a heat shock protein 70 family member with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. This gene is associated with protein folding in the ER, the ERAD pathway, protein oxidation and refolding, polyamine and carbohydrate metabolism, detoxification, intracellular signal transduction, regeneration, digestion, chlorophyll fluorescence, and responses to stress, salt, and virus. It is linked to oxidative stress response and salt tolerance traits. The encoded protein localises to the ER lumen and chaperone complex, chloroplast membrane, tonoplast, cytoplasm, nucleus, and axonemal central pair projections. Studies of related genes in other species, including BiP3, connect the family to similar chaperone and stress-response roles.
