HSP70 — Pisum sativum

Summary

PSAT1G164040 (HSP70) on garden pea chromosome 1LG6 encodes a heat shock 70 family protein with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. It 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 and ERAD pathway, DNA replication, cell development, embryogenesis, seed maturation, and response to virus and stress. The protein 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 additional domains including BAH, PHD finger, and NAD(P)-binding domains.
