HSP70 — Solanum tuberosum

Summary

PGSC0003DMG400011197, the potato HSP70 gene on chromosome 7, encodes a heat shock protein 70 (Hsp70) family member with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. This gene is associated with protein folding in the endoplasmic reticulum, the ERAD pathway, the unfolded protein response, nucleosome assembly, protein refolding, and detoxification. It is linked to stress responses, immune responses, virus responses, and virus-induced post-transcriptional gene silencing. Associations also include sterol anabolism, sucrose metabolism, fatty acid anabolism, lipid metabolism, chlorophyll fluorescence, cell division, and nitric oxide storage. The encoded protein localises to the ER chaperone complex, ER lumen, chloroplast membrane, tonoplast, cytoplasm, and nucleus. Trait associations include proline content and net photosynthetic rate. Studies of related genes in other species link the family to BiP3 and HSC proteins.
