HSP70 — Pisum sativum

Summary

PSAT3G184080 (HSP70) in garden pea (Pisum sativum) on chromosome 3LG5 encodes a member of the heat shock protein 70 family, characterized by an ATPase nucleotide-binding domain and heat shock 70 conserved signature. The product has ATP hydrolase activity, ATP binding, and heat shock protein binding, and is associated with protein folding chaperone activity. It is associated with protein folding and refolding, mitochondrial protein import and biogenesis, endoplasmic reticulum unfolded protein response, ERAD pathway, S-nitrosylation and S-transnitrosylation, DNA replication, cell development, embryogenesis, seed maturation, and response to virus and stress. Localization evidence links it to the cytoplasm, nucleus, membrane, chloroplast membrane, ER lumen and chaperone complex, and axonemal central pair projection. Studies of related genes in other species further connect the family to heat shock protein function.
