HSP70 — Pisum sativum

Summary

PSAT0SS6263G0280 (HSP70) in garden pea (Pisum sativum) encodes a member of the Hsp70 family of chaperones, possessing ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. This gene is associated with diverse biological processes including mitochondrial protein import, protein folding in the endoplasmic reticulum, the ERAD pathway, seed maturation, embryogenesis, response to virus, and response to stress. It is associated with photosynthetic rate and localizes to multiple cellular compartments such as the cytoplasm, nucleus, chloroplast membrane, tonoplast, and ER lumen. Studies of related Hsp70 family members in other species connect this gene family to traits including chlorophyll content, net photosynthetic rate, drought tolerance, plant height, and heterosis.
