HSP70 — Pisum sativum

Summary

PSAT3G178560 (HSP70) in garden pea (Pisum sativum) on chromosome 3LG5 encodes a member of the Hsp70 family of molecular chaperones, possessing ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. The gene is associated with protein folding and refolding, protein import and targeting, mitochondrial biogenesis and protein import, S-nitrosylation and S-transnitrosylation, the ER unfolded protein response (erUPR), ERAD pathway, DNA replication, cell development, embryogenesis, seed maturation, response to virus, and response to stress. Its product localises to the cytoplasm, nucleus, membrane, chloroplast membrane, ER lumen, ER chaperone complex, and axonemal central pair projection. Related genes in other species link the family to ER stress responses and seed development.
