HSP70 — Pisum sativum

Summary

PSAT1G010080 (HSP70) in garden pea encodes a member of the Hsp70 family, characterized by an ATPase nucleotide-binding domain, with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. The gene is associated with protein folding and refolding, mitochondrial protein import and biogenesis, protein targeting, the ERAD pathway, the unfolded protein response, S-nitrosylation and S-transnitrosylation, DNA replication, cell development, embryogenesis, seed maturation, and response to virus and stress. Its product localizes to the ER chaperone complex and lumen, chloroplast membrane, membrane, cytoplasm, and nucleus. Related genes in other species link the family to endoplasmic reticulum stress responses and protein quality control.
