HSP70 — Beta vulgaris subsp. vulgaris

Summary

BVRB_1G009980 (HSP70) on sugar beet chromosome 1 encodes a heat shock 70 family chaperone with ATP hydrolase activity, ATP binding, heat shock protein binding and protein folding chaperone functions. The gene is associated with protein refolding, the ERAD pathway, the unfolded protein response, detoxification, and responses to stress, heat and virus, as well as immune response, cytoskeleton and actin cytoskeleton organization, glycan and carbohydrate metabolism, and zinc concentration. Its product localizes to the ER lumen and chaperone complex, chloroplast membrane, tonoplast, cytoplasm, nucleus, axonemal central pair projection and mediator complex. Related genes in other species link the family to similar chaperone and stress-response roles.
