HSP70 — Pisum sativum

Summary

PSAT2G051400 (HSP70) on garden pea chromosome 2LG1 encodes a member of the Hsp70 family with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. This gene is associated with protein folding and refolding, mitochondrial protein import and biogenesis, S-nitrosylation and S-transnitrosylation, the ER unfolded protein response, the ERAD pathway, DNA replication, seed maturation, embryogenesis, cell development, and response to virus and stress. The encoded product localises to the ER lumen and chaperone complex, chloroplast membrane, cytoplasm, nucleus, and axonemal central pair projection. Studies of related genes in other species link the family to similar chaperone and stress-response roles.
