HSP70 — Pisum sativum

Summary

PSAT1G163760 (HSP70) on garden pea chromosome 1LG6 encodes a heat shock 70 family chaperone with ATP hydrolase activity, ATP binding, and heat shock protein binding functions. This gene is associated with protein folding and refolding, mitochondrial protein import and biogenesis, S-nitrosylation and S-transnitrosylation, the ERAD pathway, the unfolded protein response, DNA replication, cell development, embryogenesis, seed maturation, and response to virus and 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 general chaperone functions, but the specific associations with mitochondrial processes, post-translational modification, and seed and stress biology are observed directly for this pea gene.
