HSP70 — Pisum sativum

Summary

PSAT0S3930G0040 (HSP70) on garden pea chromosome CAADHX020011236.1 encodes a heat shock 70 kDa protein family member 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, endoplasmic reticulum unfolded protein response, ERAD pathway, S-nitrosylation and S-transnitrosylation, DNA replication, seed maturation, embryogenesis, cell development, and response to virus and stress. Its product localises to the cytoplasm, nucleus, membrane, chloroplast membrane, ER lumen and chaperone complex, and axonemal central pair projection. Studies of related genes in other species link the HSP70 family to heterosis, cytoplasmic male sterility, and salt tolerance.
