HSP70 — Pisum sativum

Summary

PSAT5G180360 (HSP70, PsHSP70-16) on garden pea chromosome 5LG3 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 diverse biological processes including regulation of wax anabolism, mitochondrial protein import, S-nitrosylation, protein folding in the endoplasmic reticulum, the ERAD pathway, seed maturation, embryogenesis, and response to virus. It is linked to localizations such as the ER lumen, tonoplast, cytoplasm, and nucleus. Phenotypic associations include seed setting rate, heat stress response and tolerance, and flower opening. Studies of related Hsp70 family members in other species link the family to spikelet fertility, high temperature stress response, and drought tolerance.
