BIP5 — Pisum sativum

Summary

PSAT5G108200 (symbol BIP5, preferred name PsHSP70) on garden pea chromosome 5LG3 encodes a heat shock 70 kDa protein 17, 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 in the endoplasmic reticulum, the ERAD pathway, the unfolded protein response, mitochondrial protein import and biogenesis, S-nitrosylation, seed maturation, embryogenesis, and stress responses. It has been linked to heat stress response, thermotolerance, wound response, abiotic stress response, and radiation response. The encoded protein localizes to the ER lumen, ER chaperone complex, Golgi complex, tonoplast, and secretory vesicles. Studies of related genes in other species connect the family to drought tolerance, seed weight, germination rate, water use efficiency, and protein content.
