HSP90 — Pisum sativum

Summary

PSAT2G004480 (symbol HSP90, preferred name PsHSP89.1) on garden pea chromosome 2LG1 encodes an ATP-dependent protein folding chaperone with ATP hydrolase activity, ATP binding, and protein binding functions, belonging to the Hsp90 family. This gene is associated with cellular response to heat, response to stress, protein folding, protein maturation, protein stabilization, protein import and targeting, seed germination, photorespiration, cell cycle, cell division, proteolysis, JA signaling, and S-nitrosylation. It is linked to sperm motility, sperm capacitation, and acrosome reaction, and localizes to the cytosol, chloroplast stroma, mitochondria, ER lumen, plant-type cell wall, plasmalemma, and perinuclear region of the cytoplasm. The gene is associated with relative growth rate. Related genes in other species link the family to embryogenesis and mitochondrial function.
