HSP70 — Pisum sativum

Summary

PSAT5G299000 (symbol HSP70, also known as PsHSP91) on garden pea (Pisum sativum) chromosome 5LG3 encodes an ATP-dependent protein folding chaperone with ATP hydrolase activity and ATP binding, belonging to the Hsp70 family. The gene is associated with protein folding and refolding, mitochondrial protein import and biogenesis, S-nitrosylation, the ERAD pathway, the unfolded protein response, seed maturation, embryogenesis, response to virus, and stress response. It is linked to oxidative protein folding and to the related genes BIPE3, BIP1, and PDI2. Localisation evidence connects the product to the ER lumen, chloroplast membrane, plant-type cell wall, vacuole, and plasmodesmata. Related genes in other species are linked to heat stress tolerance, virus resistance, stomatal closure, and plant growth.
