HSP70 — Pisum sativum

Summary

PSAT3G178000 (HSP70) in garden pea (Pisum sativum, chromosome 3LG5) encodes a member of the heat shock 70 family, characterized by an ATPase nucleotide-binding domain and a peptide-binding domain. The product has ATP hydrolase activity, binds ATP and heat shock proteins, and acts as a protein folding chaperone. This gene is associated with a wide range of biological processes including 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. It is linked to localization in the cytoplasm, nucleus, membrane, chloroplast membrane, ER lumen, ER chaperone complex, and axonemal central pair projection. Related genes in other species encode a 70-kilodalton heat shock protein.
