HSP70 — Solanum tuberosum

Summary

PGSC0003DMG400014212, the potato HSP70 gene on chromosome 3, encodes a heat shock 70 kDa protein with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. This gene is associated with protein folding in the ER, the ERAD pathway, erUPR, nucleosome assembly, protein refolding, and detoxification. It is linked to response to stress, response to virus, virus-induced PTGS, immune response, chlorophyll fluorescence, and pollen tube growth. Associations with metabolic processes include sterol anabolism, fatty acid anabolism, sucrose metabolism, lipid metabolism, and NO storage. The encoded protein localises to the ER lumen and ER chaperone complex, chloroplast membrane, tonoplast, membrane, cytoplasm, and nucleus. The gene is also linked to proline content and net photosynthetic rate.
