HSP70 — Pisum sativum

Summary

PSAT4G219640 (HSP70) on garden pea chromosome 4LG4 encodes a heat shock protein 70 family member with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. This gene is associated with protein folding and refolding, mitochondrial protein import and biogenesis, S-nitrosylation and S-transnitrosylation, the ER unfolded protein response, ERAD pathway, DNA replication, seed maturation, embryogenesis, cell development, and response to virus and stress. Its product localises to the cytoplasm, nucleus, membrane, chloroplast membrane, ER lumen, ER chaperone complex, and axonemal central pair projection. Studies of related genes in other species link the HSP70 family to 70-kilodalton heat shock protein function, though these associations are not yet established for this pea gene.
