HSP70 — Sorghum bicolor

Summary

SORBI_3001G419900, designated HSP70 on sorghum chromosome 1, encodes an uncharacterized protein belonging to the Hsp70 family, with ATP-dependent protein folding chaperone activity, ATP hydrolase activity, heat shock protein binding, and ATP binding. This gene is associated with protein refolding, the ERAD pathway, the unfolded protein response, detoxification, protein breakdown, response to virus, response to stress, response to heat, pollen tube growth, programmed cell death, and cell death. The encoded product localizes to the ER lumen and chaperone complex, chloroplast membrane, cytoplasm, nucleus, and axonemal central pair projection. HSP70 is linked to heat tolerance. Related genes in other species, including BIP5 and BIP4, connect the family to similar stress and protein quality control processes.
