HSP70 — Pisum sativum

Summary

PSAT1G163840 (HSP70) on garden pea chromosome 1LG6 encodes a heat shock 70 family chaperone with ATP hydrolase activity, ATP binding, and heat shock protein binding functions. The gene is associated with protein folding in the endoplasmic reticulum, mitochondrial protein import, S-nitrosylation, the ERAD pathway, and the unfolded protein response. It is associated with seed maturation, embryogenesis, cell development, DNA replication, response to virus, and response to stress. The product localises to the ER lumen and chaperone complex, chloroplast membrane, tonoplast, cytoplasm, and nucleus. Studies of related genes in other species link the HSP70 family to general chaperone functions and stress responses, though these associations are not yet established for this specific pea gene.
