HSP70 — Solanum tuberosum

Summary

PGSC0003DMG400008917, the potato HSP70 gene on chromosome 9, encodes a heat shock 70 family chaperone with ATP hydrolase activity, ATP binding, and heat shock protein binding functions. It is associated with protein folding in the endoplasmic reticulum, the ERAD pathway, the unfolded protein response, nucleosome assembly, protein refolding, and detoxification. The gene has been linked to sterol, fatty acid, and sucrose metabolism, as well as lipid metabolism, immune response, response to stress and virus, virus-induced post-transcriptional gene silencing, chlorophyll fluorescence, cell division, and nitric oxide storage. It is associated with proline content and net photosynthetic rate. The protein localises to the ER lumen and chaperone complex, chloroplast membrane, tonoplast, cytoplasm, and nucleus.
