HSP70 — Pisum sativum

Summary

PSAT3G178800 (HSP70) encodes a heat shock protein 70 family member with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. In garden pea (Pisum sativum) on chromosome 3LG5, this gene is associated with diverse biological processes including mitochondrial protein import, S-transnitrosylation, S-nitrosylation, protein import and targeting, cell development, mitochondrial biogenesis, ER unfolded protein response, ERAD pathway, protein refolding, DNA replication, seed maturation, response to virus, embryogenesis, and response to stress. It is linked to localisation in the ER chaperone complex, ER lumen, chloroplast membrane, membrane, cytoplasm, and nucleus. Studies of related genes in other species connect the family to similar chaperone and stress-response functions.
