HSP70 — Cucumis sativus

Summary

CSA_5G514500, symbol HSP70, encodes a member of the heat shock protein 70 family on cucumber chromosome 5. The product is an ATP hydrolase with ATP binding and heat shock protein binding activities, and is annotated as a protein folding chaperone. It is associated with protein folding in the endoplasmic reticulum, the ERAD pathway, and the unfolded protein response, as well as protein oxidation, refolding, and digestion. The gene is linked to responses to heat, stress, and virus, chlorophyll fluorescence, signal transduction, homeostasis, and pollen tube growth. Its product localizes to the ER lumen and chaperone complex, chloroplast membrane, tonoplast, cytoplasm, and nucleus. Studies of related genes in other species connect the family to similar chaperone functions.
