HSP70 — Beta vulgaris subsp. vulgaris

Summary

BVRB_040950 (HSP70) on sugar beet chromosome 154705 encodes a member of the Hsp70 family, a protein folding chaperone with ATP hydrolase activity that binds ATP and heat shock proteins. The gene is associated with protein refolding, the ERAD pathway, the unfolded protein response, and protein folding in the endoplasmic reticulum. It has been linked to cytoskeleton and actin cytoskeleton organization, glycan and carbohydrate metabolism, detoxification, and responses to stress, heat, and virus, as well as immune response. The encoded protein localizes to the ER chaperone complex, ER lumen, chloroplast membrane, tonoplast, cytoplasm, and nucleus. The gene is also linked to zinc concentration.
